Seth Thomas Movement Identification
Seth Thomas movement identification
Seth Thomas movement identification is a fairly easy process. ST clock movements have specific markings that identify them. Their fame began in the Antique days. They were known for making their own movements and clock cases. Of course, the craftsmanship was astounding. After the war era, they did not make anymore clock movements. Instead the use of Hermle clock movements began.
In the end
For the most part, the name Seth Thomas did not stay with one company very long after the war. The outcome of these takeovers are three types of Seth Thomas clock movements. The Antique Seth Thomas were in production during and long before WW2. The use of German units such as Hermle, as well as movements that operate by battery, also began post WW2 by Seth Thomas. Hermle clock movements are German made and of the highest quality. Clockworks offers these types of movements.
Is the clock an antique Seth Thomas?
There are a few ways to tell if the ST is an antique. The easiest way is if there are no pits in the movement plates. Please see the picture below. Notice the pattern on the outer plates. The antique Seth Thomas clock movements never had this design pattern on them. It will have ST with a circle around it for a logo. Additionally, the movement will say made in USA. They may also have a few numbers on it such as 89 or 124. It also means that it is not available new, and made before 1950. A repair would be the only option.
Modern Seth Thomas Movement Identification
The picture displays the small bumps, or pits, in the movement plates. This design on the Seth Thomas movement indicates some interesting things. In short, the date of the movement is between 1950 and 1979, and it was made in Germany. This also means have a good chance of getting a new movement from Clockworks. To get a new movement means the cost is a fraction of the price of an overhaul. It will also ship out right away. The clock will be running right away instead of months later. It is not possible to restore a clock movement so it is better than new. To order a new movement, match up the numbers on the Seth Thomas page. If questions please email us.

was given a Seth Thomas parlor clock that is missing the pendulum bob. the movement markings are :
S. THOMAS
THOMASTON CT.
U.S.A.
Also a Dimond inside of a circle with the letters ST inside of the diamond. there is the numbers 5 7/8 stamped on it and under those numbers there is 1/2 stamped. clock seems to work fine and chimes correctly. would like to know what type of bob to find so I can proudly display and use it.
Thanks in advance.
The clock movement you have requires specific parts that are no longer manufactured or available. In such cases, a custom solution or modification to existing components would be necessary. Alternatively, we can try to find a match from our inventory of spare parts.
If you are considering restoring the clock, you can send it to us, and we will assess the situation and develop a restoration plan that includes addressing the parts issue. Are you interested in sending only the movement for restoration?

I am not really interested in restoring it as its value to me comes more from where I received it. I am also not to concerned that it keeps perfect time only that it is approximate. I also found that the hammer for the alarm gong has apparently broken off from the pivot as it is missing also. I would be interested in just finding a suitable replacement for both the pendulum bob and for the hammer.
Thank you for your quick reply.

The thing is, these parts cannot be bought new as described. They are either made or robbed from a junk unit.

Have a Royal Seth mantel clock from Thomaston. Hermle movement backplate is bumpy/pitted
and has movement number A403-102. Under this is the number 8106. Clock appears to be in very good condition, but seems to need either repair or a new movement to make it function. Cant find this movement in Clockworks list.
This is the same model that was ceremonially burned in 1943. Any advice?
It will end up being the 132-071 unit we offer at this link

Did Seth Thomas hand inscribe an S and a T on the winding on in the inside?
Can anyone give me the year that the Hermle 350-060 movement dates from?
It is is my old Seth Thomas – I’m guessing early 1950s????

Hello. I just received a Seth Thomas grandfather clock, that I believe is either 1960s or possibly late 1980s and trying to date. It has a German-made Jauch movement No A407-000. Under the stamped (into the plate) name “Jauch” there is the number 96 and on the printed label it says “Made in Germany for Seth Thomas; Thomaston, CONN, USA”. Any guidance would be appreciated. Thanks, Fred
Fred – ignore my post below – I missed the part that you said it was a Grandfather clock. I can not say how they were stamped. Sorry
Check what is stamped again Fred. The reason I say that is in 1950 Westclox and Seth Thomas mergerd under a holding company “General Time”. After that the back plates were reportedly stamped “Made in Germany for Seth Thomas a Division of General Time”. In 1970 Talley Industries did a hostile takeover of General Time and the plates were then stamped “Made in Germany for Seth Thomas a Division of Talley Industries”. In 1982 Talley ordered the closing of the Conneticut clockworks and moved everything to Athens, GA. IN 1988 General Time was bought back by stockholders – it went out of business in 2001. Colibri got the Seth Thomas stuff. It is now owned by Alliance Time and they are throwing the Seth Thomas name on everthing they can.
1970s most likely. Now obsolete but we have the conversion kit at this link

Although it is for a PL93, it will also work with the unit you have

I have an old Seth Thomas “Royal Seth” mantle clock – from the Talley years. It has a Hermle 1050-020 movement from my research. I cleaned the movement with a spray acetone electronics cleaner spray to remove the build up of old oil on it. (Looked like someone had sprayed it with WD40). I then lubricated it with Liberty synthetic clock oil. I ran it for a week prior to cleaning it and it actually kept good time. Now, it runs slow – about 5 min per day. The speed adjustment is all the way to + side. Any idea what could be causing it to run slow? I’ve worked on clocks before and always had good luck bringing them back to life – but I’m clocksmith. This is the first time this has happened to me.
It was shot before you started, these are 30 year units at absolute best, yours is closer to 50

Hello,
I have a SETH THOMAS #A208-005 7003 that runs fast after fully winding… Gains about 3mins every hour.. it will slow down after a few days of running but speeds back up when the 8day comes around and it is time to wind again. I have been trying to find a clean picture of the balance wheel because i can not seem to locate the tabs above the wheel to adjust to slow the clock down. do you happen to have a pictre i can use? or have any idea what the tabs look? or instructions on how to adjust? Any help would be great thanks in advance for your support.
Timing a balance clock movement
Balance Clock Movement Timing is done fairly easy. There are three types of clock balance movement styles post 1950. This section is for those balance units that do not have a platform escapement.
The platform escapement can be read about in another section. These notes are only for the larger balance wheel in the top center of the clock movement.
For example, movements in the Urgos 6/ series and many of the Hermle clock movements. Hermle movements such as 340-020 and 350-020. Out of these, two styles, the old style and then the new style.
Use of the old style was all through the 70’s and 80’s and 90’s. Around this time there was a switch to the new style on the Hermle units. By this time the Urgos units were out of production.
The old style
The old style is one with a round spring that goes up and down (Vertical). It goes in a circle around the center arbor of the balance wheel. In this style there is a slide arm with a tiny weight on the balance wheel itself. There is a + and – on the wheel. To speed up time go towards the plus sign.
However this style is not always easy to regulate and can be very hard to get it perfect. The factory has special devices to make it perfect. However it’s not that easy on the customer end with this style balance. For this reason it has been improved upon during future manufacturing.
If the old style balance then the clock movement has some age to it. If this is the situation it is just best to replace the unit with the new one. Clockworks offers the movement brand new with the new style balance for less than the cost of a cleaning.
The clock movement has lasted 25 years or more. In theory the new unit should last more than this with the improved aspects.
The new style
The non pendulum units offered on this page all have the new and improved balance assemblies. Despite the change on the balance, these units are a direct fit and will install in the clock case the exact same way as the old unit.
If the numbers match from the old unit to the numbers offered on this page, than the movement will be the exact same. It will be the same as it is now but brand new and with the improved balance.
The improved upon balance units have a different kind of hairspring (Horizontal). It will also have a screw to regulate it rather than a slider arm. The regulator screw is on the back of the movement near the balance.
There is a + and – sign next to it meaning fast or slow. If the clock needs to be faster to keep time then the screw would be turned to the plus and opposite for slowing time.
The factory times the balance movement before the new movement ships. The movement has a slider arm on the threaded portion of the timing adjustment screw. This arm pulls or pushes the horizontal hair spring and makes the clock run faster or slower.
When the movement leaves the factory this arm is in the center of that threaded rod and is timed while the arm is at that location. During shipping it is possible for this arm to jump out of its center position and, in turn, make the timing out of whack.
The solution to this is to first just lift that timing arm with fingers and move it to the center of the threads again. This is where timing begins.
After it is in the center of the threads it will be pretty close in timing and only will need fine adjustment with the screw, moving it too the plus sign for faster, minus sign for slower.

Hello!
I have the same question.
The logo on the plate (which is smooth) is ST in a diamond within a circle (upper left). On the lower left is the number 89J.
The label is shot except for part of the word Sentinal an what I believe is part of a 7.
The hands have an S and a T at their bases (S on min a T on hour).
I picked this up at (of all places) a car junk yard and it’s in pretty sad shape. I’m trying to decide if I should leave it be (is it special…or more special) or if I can be comfortable repairing the case myself.
That one is a true Seth Thomas made in CT USA, an 8 day time / strike spring driven unit made 1930s – 1940s mostly.
Should the case be fixed? Up to you, not sure from here

This is more of a comment as I just came into an OB McClintock bank clock that was turned into a Grandfather clock of sorts. I have a friend that works on clocks and he just basically cleaned and oiled the movement which is a Seth Thomas 85A, he says 1917. My wife saw it an estate sale down the road. The clock has been running over a month now and keeps perfect time. It looks original ( aside from the added base ) with the stained glass door and 2 locking mechanisms for the door. It used to have electricity hooked up to it to run the banks chimes which were separate. Enjoying your website.

I live in Australia. I have two Seth Thomas wall clocks which I bought at auction 32 years ago. Both have run flawlessly until recently. I know nothing about them but I believe they are antique. The Octagonal railway/school wall clock looks to be the older of the two and recently stopped running. It is marked ST surrounded by a diamond and an outer circle. It is followed by the inscription “MADE IN THE USA AMERICA”. Bottom left it is also marked below the winder 8 1/4.
I have removed the movement from it’s case. The only other mark I found anywhere was a pencil incription on the back of the case KE958?
Can anyone tell me the age of this Seth Thomas clock? I’m thinking first decade of the 20th century? I would like to be able to find a replacement escape wheel (40 tooth approx 32mm diameter) plus the correct Verge for the clock. Thank you so much for any help you may be able to provide
It would be made between 1850 and 1940.
The only way to correct the escape wheel is to get a junk movement for parts, or correct the one that exists.
No parts are made for that unit.

I just acquired a Seth Thomas grandfather clock which is chain driven. It’s not yet set up but I’d like to know how to turn the sound off and on as I can’t seem to locate a way. Thanks
Not all have a shut off or silence switch. And then some do but the dial does not have the slot for it to be adjusted by means of the front of the clock and dial. If you look at the movement from the back please see if there is a lever sticking out the left side middle on the front side of the movement. That is to say your left as you look at the back of the movement. If there is a lever, down is chime on, up is chime off.

Have a ST mantel clock with a face in each corner of the clock. It does have 2 areas to wind it. Is there a special name for this ST ?
I was just wondering what my Seth Thomas mantle clock is worth.
The value of the mechanical Seth Thomas clock varies greatly depending on age, quantity produced, and if it is sought after.
The Seth Thomas name has been used on so many clocks that are true ST and not really true ST depending on if it was before the name was sold out or prior to this.

My pre 1867 Seth Thomas column and cornice triple deck mantel clock has the number “18” stamped on the bottom left corner of the lyre (harp) brass movement frame. What does that mean?
i have a Seth Thomas battered operated clock was my mothers 1978 was when it was made numbers are E687-251 I need a new movement i think. it wont keep time or chime, where can i get one? my husband does some clock repair so hope he can fix it if i can get the right parts.
Best to swap that one out as it is no longer made, you would need to put any other quartz unit in there with new hands.

That particular unit is no longer in production and not available new. However you can put any quartz unit in there that you want instead as long as you get new hands also. Please see our fine collection of chiming battery operated clock movements at this link

I have a Seth Thomas “floor” clock (Grandmother? @ 6′-2″) bought at Basco’s (no longer in business – like a walmart) bought it in 1979 for my folks for under $100. Pendulum just stopped. Never moved, fallen etc. i took out the movement and cleaned and used a little clock oil as well. all parts appear fine, suspension spring etc. pendulum is mounted correctly but seems it for some reason needs more room for the 2 ‘teeth” at top to engage the gear to turn minute hand. its possible the weight was pulled up to far but have since gotten the chain/weight lower. Any ideas as to what this may be? i have been looking for a movement to replace existing one which is an A403-010 (possibly manufactured by Hermle?) mine is an A403-010 and ive found an A403-007 – would that work if unable to fix current movement?
Thank you very much
I have a ST wall clock with a label on the back that reads 5112 General time Corp. Can I get parts and what is the mfg date on this clock
I acquired a Seth Thomas petite #3 and need a schematic of it to take the clock apart and put it back together successfully
I just purchased a vintage Seth Thomas ships clock in a Bakelite case. It has a double-winder mechanism. Does one of the winders wind a chime mechanism? When I wind the clock, it works, and it seems to keep good time. It does not chime.
Sometimes those old ships’ clocks had two places to wind, just for the time keeping. Sounds like that style could be time only with no strike.

Looking for replacement numbers (just bought the clock) for a clock from 1978. The numbers on the plate are 451-050. The original paper work is with the clock, but it obviously has had a rough life.
Yes we have that movement available – it is one of our most popular movements.
It can be found at this link: https://www.clockworks.com/product/new-451-050-clock-movement-by-hermle
All you have to do is select the proper cm length (stamped on the movement right near the movement number) and add it to your cart.
If you need help with the installation please do not hesitate to email us – clockworks@clockworks.com
Many Thanks !

I recently moved my Seth Thomas grandfarther clock from one room to another by sliding along the floor. Now the hourly chime goes off at 15 after the hour and subsequent chimes are 15 minutes off. Would you know what caused that and how to fix it? Clock was made around 1985.
For that one you can go back ward with the hands. Go back ward with the minute hand 15 min, then back forward. Problem solved
James
usually when a clock is moved, the weights and the pendulum should be removed. this can throw things off when it is shaking around. easiest way to remedy this is to turn the minute hand until it chimes the 4 quarters then strikes the top of the hour. once it strikes the top of the hour, remove the hands and then replace them to the correct time. once this is done, you can advance to current time. –Bob
I have movement for an ST Round Band, stamped with Plymouth. Trying to find the adjustable bob sized right for this clock. Any help?
Not sure from here, can I see a pic of the back of the works? Please email it to clockworks@clockworks.com with the same question

I have a Seth Thomas grandfather clock I believe was purchased in 1985. It has 3 weights in cables. Only the center one drops. Is this correct or are all 3 suppose to drop?
Dennis
all 3 are supposed to drop at a even rate. the chime side is getting hung up. if the chime fails to function, the strike will not function. there are some numbers on the back plate of the brass movement itself. these numbers will help identify your clock movement. these are 25-30yr movements.. yours
