I’ve just completed (well I thought I had) my first wristwatch strip down, service and reassembly. A little more challenging after solely doing pocket watches to date. Anyway, getting towards the end of reassembly I noticed a collar in my dust tray and for the life of me, I can’t see where it’s supposed to go. I’ve circled it in red in the photo. Presumably part of the keyless works? Can anybody shed any light please? The movement is from a vintage Technos manual wind watch, probably from the mid 50s, which is identified as F391 (Felsa).

 

Thanks

Sometimes there are little metal washers like these underneath the crown wheel...is the watch winding and setting ok?

Thanks, for pointing me in the right direction. It wouldn’t fit underneath the crown wheel but as a washer underneath the yoke screw. Well it all works okay and sets and winds good so I think that’s sorted it.
Cheers,
Adam

Nothing is as unsettling as completing an overhaul and discovering some little part reappearing out of (seemingly) nowhere. Now you've not only fully completed your first overhaul, but successfully figured out a problem....Outstanding!

      L&R Varimatic Needs Adjustment

      By clockboy · Posted

      Welcome to the forum, enjoy. I have a varimatic that went  out of sequence because it’s hydronic oil ran very low. Must admit it’s still in my garage just know time to fix it. Purchased a cheap Indian Junta/ sonic Pearl as a stop gap a few years ago and it still performs perfectly so no incentive to fix the Varimatic.

      Is this a 'hack' ?

      By dnhb · Posted

      The plate is OK, thanks. It seems the answer to my question is that this is a 'hack' & for me another reminder that in general, one won't be the first person to be tinkering with an old timepiece!. As you day, I've been fortunate to have gotten some good advice and, just as important, encouragement. I've been lucky then not to have the balance spring break as a result of my novice 'ministrations' - but I did remember to 'stroke' rather than bend per se. The clock is of sentimental value to the owner so I'm relieved to have now got it running to time with the support & encourage of forum members like yourself.

      L&R Varimatic Needs Adjustment

      By storminwestie · Posted

      Recently purchased a L&R Varimatic knowing that the piston does not fully rise in the cylinder. The likely cause is air in the system. The manual calls for using a bleeder cup, which is as rare as hen's teeth.Does anyone have any experience with this issue and if so, how did they resolve it?
