Hi guys,

I've had this Felca Automatic for a while and its been a bit sluggish so I thought its high time it a service.

One area I wanted to fix was the date change was not 'snappy' and it seemed that the corrector was not fully home after midnight as the date would not centre in its window unless you have it a sharp tap.

Turned out the date wheel is a bit worn so the problem remains. Date wheels for the 2452 are available but for the date at 'six' not so much.

Here's some pics.

Its hard to see in the pic below but it reads 41 jewels on the rotor!

A sure sign of the sixties....rockets!

A bit plain but the date at 6 gives it some character.

Final shot.. an original Felca crown..for those who care about these things.P_20170721_155220.thumb.jpg.f1df9e37798fb1f757b11b488cd005d7.jpg

Basically a typical ETA watch, well designed and produced. One thing I did was to tighten up the clearance of the rotor. This is a plain bearing design which screws from underneath. The screw forms one bearing surface and the rotor the other. By reducing the height of the post on the rotor you effectively close/tighten up the bearing surface thereby removing play. You can only do this a few times ..sooner or later the rotor will hit the bridges. If you're trying this..remove small amounts at a time. Too much and the bearing will be tight.

      @oldhippy, hasn't been on since the 14th of April, I messaged him nine days ago, no reply.  I  hope he's on an around the world trip with endless booze and supermodels.   joking apart, I  hope he's alright. Does anyone know anything?

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

      Some of the older American companies did at least claim to manufacture them so reliably that any one of their tailstocks should perfectly center any one of their headstocks. But it would take probably someone like nickelsilver to verify that in a big enough collection.

      You also have another potential issue with head and tail stocks, in my research it would seem that for the American style lathes the head and tail stocks were bored as a pair. So a matched pair is good a “pair “ made up from two different lathes cause some headaches. The Swiss Geneva style lathes are much lighter but were apparently made to fit any lathe. I have seen mention of being able to shim the tailstock as well to true up. indexing is again not so straightforward for a watchmaker lathe, at least not as I have found so far. Often a lathe will come with basic indexing which is limited to 60 positions. The full index plates do come up at times for eywatering prices. It is very possible to do that electronically. As well as what @SwissSeiko maybe able to point you to have a look here. https://imakewatches.com/projects/CNCIndexDriver.html   https://imakewatches.com/projects/MillingAttachment.html   Tom

      On a watch repair discussion group that you know that we love to see naked watches out of the case you show us a box? I think a book on watchmakers lathes should be helpful.   The watchmakers' lathe, its use and abuse; a story of the lathe in its various forms, past and present, its construction and proper uses by     Goodrich, Ward L https://archive.org/details/watchmakerslathe00good

      Got it. So a WW lathe will have that graduated drive pulley for different speeds and similar setup for the bed and tailstock, but they won't be fully compatible with one another in terms of parts. Thanks! The picture helps a lot.
