Hermle 451 clock movement

Being one of the most produced movement in the clock world, the Clock movement 451 Series is very popular. The 451-050 and the 451-053 are only rivaled by the 340-020 mantle unit for quantity produced. A Hermle 451 Series clock movement will work for 25 - 30 years night and day with out much complaint.

The movement

A grandmother sized clock case would except the Hermle 451 Series clock movement perfectly usually. This clock movement has square outer movement plates that are 120 x 120mm. A chain driven, three weight, Westminster chime clock movement, that fits into tight places.

Pendulum, chimeblock, dail or weights sold separately. Hand nut, chains, suspension spring and leader come with the new Hermle 451 Series clock movement. Chains, leader and suspension spring included. It is basically everything that comes out with the two screws underneath removed. With so many sold, the part and component availability is high for the 451 clock movement, this cannot be said about many other clocks.

Are there any dial faces available for a Hermle 451-030 cm66 movement?

I just received my Grandfather’s grandfather clock (don’t know who made it). It has the 451-050H, 85cm, 70.777 mechanism. I have finally got it “hooked up” and running, however the pendulum gradually slows down and eventually stops. Is there a calculation as to where the bob(?) (just learning – circle at the end) should be positioned in order to keep the time accurately? Any “manual” information you could provide would be greatly appreciated as well (links). Thank you.

My hermle 451 movement chimes are playing too fast. Some kids tampered with the weights and chains….left chain was pulled off the wheel and the right chain was pulled down too far.
Right and left weights were removed.

I managed to replace the chains in their correct place on the wheels and hung the weights again…but the chimes are now too fast. Everything else is working correctly.

Another thing is that all three weights are equal…this is is the way I received the movement kit when I ordered it. All three weights are 6 lb.

I have just purchased a clock with this movement. It is missing the pendulum and the weights. I think I have the pendulum figured out. I was wondering what size or weight weights were needed? Looks like it needs three total. Thanks

I have a 451-050 and I would like to know which weight goes on what chain? There are 2 weights that appear to be the same weight and a third which is quite a bit heaver. Where does the heavy one go on which chain form left to right.
Thanks Alex

I have a 451-050 movement that I think is working OK. It only rings once on the hour.. Is this movement supposed to ring as if to count the hours? such as 4rings at 4 o’ clock 10 at 10 etc.

I have a 1970’s Hamilton grandfather clock with a 451-050 Low bridge movement, 3 weights. It hasn’t run for a decade. The suspension spring was broken, It had been replaced before and removed. Apparently, that’s how to adjust the beat? Anyway, the chime side weight (right side looking from front) just falls. Is replacing the whole movement my best option? I think it is. Also, will I need a hand puller? Thanks!

Hello, I have a 42 year old Hermle 451-050 that works great with one exception. It chimes perfect every 1/4 hour, but only “STRIKES” every other hour. The pin that lifts the rack is catching on the rack after the odd strike. Is there a way to adjust this cam/pin or is the movement wore out? BTW, it was cleaned and oiled recently.

Thank you for your quick reply. I was thinking along those lines but , when I tried to turn the cam it didn’t want to budge and so I chickened out. I will try again now that I know for sure it’s a friction fit. Again thank you.
