Elgin 685 Adive


Tudor405

Recommended Posts

I have just acquired an Elgin watch with a broken 685 movement. This movement has a double sweep second wheel situated on a pinion attached the third wheel arbour through a jewel in the top plate. I appreciate that double wheel arrangement is designed to control the indirect sweep hand stutter. My problem is that should I be able to find a donor movement I cannot see how to install this arrangement. It would seem logical that the train wheel s are installed in the usual way leaving the top pinion protruding and then the double wheel arrangement fitted but I cannot see quite how this should be done as the part retaining the wheels do not appear to want to come off the pinion

Any advice would be welcome. I attach some photos of the offending part. As you can see both the top and bottom pivots are snapped.

    • I looked at it like this, I've built a lot of stuff in my time, building structures and furniture,those are my creations and they will still be here way way after I'm gone. Traditional watchmakers felt the need to pass their knowledge on, ideas that they created . I assume with them as it is with me, leaving their mark on the earth, a way of being remembered. This creation of Mark's has brought thousands of people together to pass their knowledge around,  ideas that will continue to be used for lifetimes. Ideas that should continue to be procured. If for whatever reason the forum ceased to exist, not quite like Ranfft's, that didn't disappear but much less usable. Then that is sad, such a massive loss of communication between good people and a wealth of knowledge lost. There should be something in place for when that happens which could be next week, next year or in 10 years. Might not be a topical subject for a lot of folk or boardering on controversy, i did say i talk about stuff other people dont. But if you dont talk about it and something happens then you've lost it and you ain't gonna fix it .
    • I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward? some kind of WRT ark
    • That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much. 
    • Yeah ive watched that a few times before,  i couldnt find my old school dividers to scribe it up 😅 Yep thats the guy i bought a roll from . Thanks Nicklesilver that answers that perfectly and more or less what i thought an experiment over time would prove . The jumper arm is quite thick along its length, i left it that way intentionally, i thought the original was probably very thin, i didnt see that it was already missing. Setting isn't particularly stiff as such just positive, i still need to take it out and polish where it mates with the stem release. 
    • Yes, "Sold out" is difficult to understand. There doesn't seem to be a lot going on. It's been nine months since any new video was published on the Watch Repair Channel. The Level 4 course on watchfix.com has been in progress for what feels like forever (several years!?). Maybe Mark's enterprises aren't doing well or perhaps already so profitable there's nothing much to motivate him for more material. Or, perhaps these days he's more into crochet. The real reason is probably something entirely different but it would be nice/interesting to know. I don't mean to sound gloomy or pessimistic, but I wouldn't be surprised to be met by an HTTP 404. Every day feels like a gift. Speaking of watchfix.com I've been postponing the "Level 5: Servicing Chronograph Watches" course for a very, very long time. Anyway, I just enrolled on it so it's going to be very interesting to see the videos. I must say, IMO there's nothing really that can compete with Mark's courses when it comes to presentation and video quality. It's simply world-class and makes me associate with some really expensive BBC productions.
