I can’t quite make it out from your pic but the one that is I think 4.11. If so your pendulum should be 133mm. This taken from the top of the suspension spring to the centre of the Bob.

Looks like 758 this is the movement number.

4 11 is the length in French inches

The date is 1888

2.5 oz is the most popular weight. So I would go for that.

Thanks for that oldhippy can you still get a double ended key for this clock given the age. Also it has a regular mantle clock suspension spring or do they have a much longing spring.

Yes you can get keys. This is the type key you need. The suspension springs also come in different sizes. If you have the old one measure the length.   Could you post a photo of where the s/s is fitted then I can be more precise on which one to buy. Any good suppler with stock both of what you need.

Here is the photo it measures 30.1 mm and has two plastic ends instead of brass by the look of it is that normal on a clock from 1888

Good you have the old one or through as it has plastic ends its not that old. Just order a replacement of the same length, my preference is for brass ends as the original would be brass but its up to you.

      Calendar work certina 25-651

      By tonydagee · Posted

      Hello all, just disassembling to service, but I can’t figure out the working of the calendar work…it’s not operational the jumper and spring are ok, but the operation of the driving wheel has me at a loss. I can’t see a cam to drive anything. Is something damaged or missing? Help please!

      Unusual Seiko dial damage

      Believe the relume (not a fan) was done a long time after the damage.

      I can only think of some chemical reaction to reluming

      A lathe with indexing that won't break the bank?

      By nickelsilver · Posted

      I have a little milling attachment for my WW lathe, but very rarely use it and not for wheel and pinion cutting. For that I use a small Sixis 101 milling machine. I normally do direct dividing, but sometimes have to do an odd count and use the universal index which also fits on the Sixis.   Back in the day when I didn't have a mill, I would cut gearing on my Schaublin 102. It has a universal dividing attachment which fits the back of the spindle. Both it and the one for the Sixis are 60:1 ratio, and with the set of 4  index plates I can do almost any division. When I've had to do a strange high count prime number, I print a disc with the needed division and just place the plunger on the dot. Any position error is reduced by a factor of 60 so still plenty accurate.   The machines are a mess in the pics as I'm in the process of making a batch of barrels for a wristwatch 🙃.   This is the Sixis. The head can also be placed vertically, as can the dividing spindle.   Dividing plates. The smaller ones fit another dividing spindle.   Universal divider for the Sixis. I put it together with parts from an odd Sixis spindle that takes w20 collets, like the Schaublin 102, and a dividing attachment from a Schaublin mill.     The dividing attachment for the 102. The gear fits in place of the handwheel at the back of the headstock.   And the little milling attachment for the WW lathe. I just set it on the slide rest to illustrate the size, you can see from the dust on it it really doesn't get used much. I think only when I change bearing in the head, to kiss the collet head seat (grinding wheel still in the milling attachment).

      Opinions on Seiko's 4R and 6R movement quality from those more able to judge

      By SidKop · Posted

      I read a lot about the quality (or lack thereof) of Seiko's 4R, 6R, 8L  movements...or more specifically the lack of regulation from the factory. Especially when compared to similar priced manufactures using SW200's or ETA's. I thought I'd ask those more in the know, do the 4R's and 6R's deserve their bad reputation, is it fairly easy for someone with minimal skills (or better yet a trained watch mechanic) to dial in these movements to a more acceptable performance.    For background I spent more on a 1861 Speedy years ago, expecting that the advertised 0-15s/d  would probably perform more like 5-7s/d. In reality it's been closed to 2-4s/d.
