In need of a little help, I currently have a winter Haller and Hof Meier Fusee time only movement with platform escapement. 

Now the platform isn’t the original, so firstly does anyone have one for sale, or a picture/measurements of an orginal. 

Secondary and also a major problem is the entry pallet jewel has been replaced with a piece of steel. 

I found the reason for this and it’s because the pallet jewel holder had been broken ( where the jewel sits sandwiched between the upper and lower bits the top bit had snapped and been soldered on with the new bit of steel for an entry pallet ).

The picture shows the exit pallet jewel as it shows how it is sandwiched between the jaws of the pallet. 

The repair was reasonable but it lacked enough depth into the scape wheel teeth. 

So next ask, does anyone know of where to get clock pallet jewels all my suppliers just sell the Brocot style and not lever type. 

Any help greatly appreciated.

Hi no idea really at my age to fiddly.  Ihave done the W&H. Mantle clocks but never had one of those with a platform.  The last platform clock I repaired was cobbled to gether from various platforms to get a working one.. there are many generic platforms but some require re drilling the plate, I take it you are trying to stay true to the clock.

Haller and Hof Meier made so many different movements it is probably imposable  to get  the proper replacement platform. I must say the one you are showing looks good the same colour brass as the movement and looks correct to the plate. When you have large pallet jewels that need replacing steel is normally the preferred replacement.   

If this was in my workshop. I would make a new steel fitting to hold the pallets

      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.
