    Strange hand issue

    I would guess that there is a flaw in one of the gear train gears that correlates to that time that is causing it to get hung up. but that's just a guess, and I'm still a noob around this stuff. I'm imagining a slightly bent tooth that grabs on a plate or something. As an aside, that is a super cool watch, I hope you get it going 100%. Any interest in selling it if you do? I love old Hammies.

    Open ended watch strap

    Oh, and of course you could always go with a NATO or ZULU strap. I imagine a nice distressed leather one would look sharp on that watch.

    Open ended watch strap

    There are a bunch of options here: https://www.watch-band-center.com/watchstrap-h175-Open-End-Watch-Bands.html I'd be inclined to go with one of the Hirsch though. You know you're getting quality, and it's got to be worth $40 to have something proper for an heirloom you've already put so much effort into.

    Tension v non tension crystals

    Just a note on the claw. If you don't have one already, I'd put off ordering them. They only work with crystals with very vertical, tall sides. In every case I've tried to use one, it's failed, and I've ended up using my press instead. I'm sure there's some situation where they are the better tool, but I haven't found it yet.
  5. They are replaceable, though I don't know the details of how it's done as I'm also a newbie. Here's one possible source for parts: https://www.esslinger.com/hole-jewel-assortment-for-watches-100-pc/

    Part placement on seiko 6119A?

    Here's another similar part on the 6119C:

    Part placement on seiko 6119A?

    This is a different movement, a 6138 I think, but I wonder if it serves a similar purpose as the plate I pointed out with the red arrow? That would explain the wear pattern, and it looks like it might fit there:

    Part placement on seiko 6119A?

    Looking closer on the wear on the back of the piece, it looks like the pattern there is about the same size as the center wheel, if you set it so the cannon pinon pokes up in the indent on the side. I have a hard time imagining what that would be for there, but I wonder if those wear patterns might give you more clues if that's not a fit.

    Part placement on seiko 6119A?

    This looks like a list of all the service manuals for Seikos, and all three variants of the 6119 are there: https://www.thewatchsite.com/14-user-manual-technical-manual-casing-guide-downloads/15-seiko-calibers-technical-repair-manuals.html EDIT - Dang, doesn't look like there's much useful info there....

    This video claims to be a 6119 teardown: You can probably get some good clues there.

    Proper tool for this C ring?

    It should just pop off with a little push from a pair of tweezers or similar. You can see a complete teardown of a similar movement here:
  12. If you do decide to go the DIY route, I'd suggest chucking the nail into a drill (ideally drill press) and turning it down against sandpaper. You'll get better results than trying to do it against a grinder. It's all but impossible to get something with a perfectly round cross-section by hand with a grinder.

    What is this bezel part?

    Looks like a tension ring from the crystal in that got left behind when you popped it out. These are also called "armored crystals".

    2801-2 Lessons?

    I have sort of the inverted issue. I'm looking to branch out into Seiko's (6619 and the 7xxx line are what I own already) and am looking for good resources for the getting started with that. I've found some tear-down videos online, so I'm tempted to just dive in. I've only worked on Russian movements that I've been willing to break, so I unfortunately don't have a good recommendation for learning the ETAs, except that I'm also looking at signing up for either the Timezone course or the watchrepairlessons courses here.

    DeWalt Timex Ironman

    Unless you have another watch you can steal them from, it will be hard to say that they are "screw x". You should be able to get those from a normal fastener supplier though. You just need to know the thread pitch, diameter, and length of the screws. You can measure the thread pitch with one of these: https://en.wikipedia.org/wiki/Thread_pitch_gauge Note that metric and imperial systems measure screws differently of course, so if you're having trouble getting something that is exactly right, try using the other system. Googling around should get more details on getting the right measurements.

    How to store watchparts

    I've spent a lot of my career managing fleets of computers, which for this area are very similar to watches. What I did there was assign each one a serial, and note what was missing / broken from that particular computer in the inventory for it. I imagine a similar approach would would well here. Each individual watch or movement gets a bin, with a notation on what's missing / broken. As you pull parts, that list gets longer. Could even make it a checklist for most things. The only place it falls down is if you have parts that aren't in a movement, then you need a place to keep those straight. For those, I'd be inclined to treat it the same, but the plates are among the missing pieces. Then, as you collect pieces for that movement, you can add them. Unless you get to the point that have many duplicates of the same part for the same movement, this won't get too inefficient, and it avoids the labor of "parting out" a bunch of stuff and the risk of loss / breakage that introduces. If that does happen, you can always create another system / exception for that. At the scale I'm at I just use a multi-compartment parts bin and keep all the pieces from a given watch in a bin together, and whole watches in another multi-compartment bin. I have slightly less volume than you though, so I don't know at what point that will fall apart.

    Newbie from Denver

    I've been a member here for a bit, but I'm just now getting around to posting an intro. Getting into watch repair, restoration, service, and someday hopefully mods and new builds. I've always been mechanically inclined, and do some silversmithing and blacksmithing. Recently had a long dormant love of watches rekindled. I'm solidly in the "knows enough to be dangerous" stage of my learning. Hoping that being aware of that will prevent too many casualties! I've really appreciated the feedback I've gotten here so far, and hope my limited insights have been able to help others. I'm really gaining an appreciation for unusual vintage pieces, and so I'm hoping I'm able to breath some new life into the ones I've found so far, and hope to continue finding.
  18. I'm just getting into repairing/restoring vintage watches. Mostly for fun. I have several which I absolutely cannot get the backs off with the case knife I have. I'm considering just trying my luck with a better case knife as the one I have is definitely a cheapie, however I also found the Seiko S-261case back opener: https://www.esslinger.com/seiko-s-261-easy-snap-case-back-opener/ It's a rather expensive tool since I'll not likely be using it to generate income, but I wonder if it might we worth it. Do any of you have experience with this, or similar, tools? Would you recommend one, or is there something out there that is a step between this and the cheapie case knife I have? Would a better case knife really be that much better?

    Seiko S-261 opinions?

    That is super cool. The historical angles, the "life" that watches have is one of the reasons I love them so much. The piece that is really responsible for getting me into it is a 1941 Hamilton Lexington I inherited from my grandfather. One of the more interesting thigns about it is that it is engraved on the back so it was probably a graduation gift for him, but no one in my family can figure out who the "from" initials belong to. I like to think it was his secret girlfriend...

    My watch and the one you found are close cousins! Mine was made same year and month, SN is 6D10361

    Seiko S-261 opinions?

    Thanks again for the insights on this tool, much appreciated. And yes, no intention of changing the day wheel. I've long wanted to learn Japanese, so learning to use this is one small way I can move that goal forward a bit. Really I just want to get some dust off the dial, maybe replace or at least polish the crystal, and get it running right. Everything else, case character included, will remain.

    This looks promising:
  25. Just noticed your response here, sorry for the delay. You going to send it back to Seiko? I just noticed when browsing Esslinger the other day they have Seiko movements, including a few solar: https://www.esslinger.com/seiko-watch-movements-original/ I wonder how involved a swap would be? Seems like it could be hairy.
