Just out of interest - what are the angle marks on the movement front ?

[mikepilk]

I don't have a problem - but just wanted to know what the angle marks are on the front of movements ? , e.g.

The top one is a New Factory Tavannes 38 (Eberle 38) from a Waltham wristwatch I just bought.

I didn't spot it at the time, but the dial states 17J and the movement 15J !

on the last watch,  i notice the "timing  lever ?",   is in full retard +.  that might mean it needs cleaning?  vinn

It certainly does, I just stripped it down today.

As you can see, there is no balance shock system, whereas the info in Ranfft shows what looks like Incabloc.

The balance cock jewel is removed by screws on the underside. 

Is this an early version of the NFT 38 movement ?

I had posted a quiz about that recently but I think nobody took it up  

These are for timing regulation after assembly, using a temporary minute hand, a loupe and a reference clock.

Makes sense, Thanks jdm

here is a quiz for you,  how do you change a clutch in a 60 ton tank?  vinn

The marks are just a guide to see if the watch is running properly. Basically you would install the minute hand and note where the needle was. ... check again one hour later and see if its at the same mark.

Not very accurate and that's probably why you don't see this from the late sixties onwards.

First you need one of these screwdriver looking thingys to open the case.

Which end of the screwdriver looking thingy do you use ?

[mikepilk]

Yep, those will work as tin openers 

[vinn3]

good answer chaps.    actually you don't bother with the clutch,  go back to the supply officer and get another tsnk.

You put in an emergency leave pass, and hope some other poor sucker gets the job!

[vinn3]

the real question is " how do i start to work on a watch"?  my answer is know how open the case back and get the stem out.
