Clock Key Size Chart to get the Right Key

Can someone advise me please as to what size key(s) my Gilbert clock would need?

It’s a 3 hole clock. I’m unable to post a photo.

I was gifted a Gilbert 1807 mantel clock. it came without the keys. what size key should I purchase? thank you.

I have a Elliot 8-day lever westminster chime clock from circa 1970 without key. Any idea of the size please

Grandmother left an antique New Haven 30 hour wall clock. It is missing the key and the pendulum. Do you know what size key and pendulum are needed?

I am looking at buying an 1880’s Ansonia Royal Bonn porcelain 8 day clock. What size key do I need? Thank you very much.

I just picked up a 1920’s Waterbury mantle clock at an auction but it has no key. The only key I have, which was to a 1980’s wall clock (long gone) is too large to wind the mechanism. I’m having difficulty in understanding what exactly one measures to determine the size key needed as only a small square sticks out of the front of the clock. It appears the same key would be used to wind the chime as well as the clock Any idea what size key I would need for this? thanks in advance for any advice you can offer.

I picked up a Bell Clock Co. 8-day bell strike mechanical clock recently, without a key. The two square winding shafts look to be 3/32″ across the flats, or a little less than 2.5 mm. Is a 1 key the proper one for this clock? Also, I don’t know when it was last serviced; it was not warranted to be in running condition. I have some instrument oil; are there any oiling points inside which might be user-serviceable?

Also, do you work on pocket watches? My grandfather’s railroad Hamilton 992 was serviced by a local watchmaker about ten years back, but the watch is no longer running and the watchmaker has gone out of business in the interim.

Just acquired a Howard Miller wall clock #648 wall clock. It came without a key. I have several clock keys but none fit and upon closer inspection, the shaft seems to have protrusions or extensions at the 4 corners. Is there a special clock key for this type of shaft or do I just need a larger key?

Please do you happen to know what key size will be required for a Haller Foreign UR movement. 12cm 190,66.
3 winding holes. Its a Westminster 8 day mechanism. In a mantle clock.
Thank you.

Female here so I really didn’t understand all the stuff explained, I have a landshire mantle clock can anyone please tell me what size key thank you 👍

Good People, Great website by the way. A great find. Question. I have a Maritime Seth Thomas clock and no key. Is a number four key proper? I ask because when you get to 3 mm its hard to measure without a caliber which I don’t have handy.

I have a Trend Clock (Zeeland, Michigan) from the 1950s; could be older. The clock number is 69308. When measuring the key shaft, I determined that it’s 3mm or 3.25mm (not totally sure). What is the correct key for this clock? And also, what direction do you turn the key to wind it?

I have a New Haven Clock Co, eight Galic(?) Day Cabinet. Any guess at key size. Or, how can I measure width when they are recessed? Thank you!

These keys do not fit winders on E. Ingraham clock

I have an e. Ingraham co. Bristol Conn. USA mantel clock, came with the two keys neither key fits the time or chime posts.

I have a 1920s Seth Thomas Cymbal #1 mantle clock. I need a new key. Measuring the shafts is difficult because they are somewhat recessed. Just eyeballing it with my dial caliper, 3.5mm looks too big. 3.25mm looks about right. Thoughts?

I was gifted a Forestville 8 day mantel clock with chimes without the key. I took it to a local jewelry store who ordered some keys but none fit. How do I find the right key.?
