    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.

    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

    Thanks so much for the extra info! I'm in Denver, Colorado, US

    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:
  9. 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.

    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.

    Seiko S-261 opinions?

    Thanks for the pointers on both dating the watch and the tool recommendation. It says "waterproof", so that would put it as '66, but I think it's a JDM model as the day wheel only has Kanji days, it's not one of the multi-language ones, if that matters. That tool does look interesting, and I like that it's half the price of the S-261. I do have a crystal / back press already, so replacing it shouldn't be a problem. Yes, I'm coming to love this watch. I originally got it as a stop-gap before I can afford a 50's or 60's Omega Seamaster (ideally one of the crosshair or honeycomb dials) but the more I live with it, the more I think an "upgrade" might not be needed! Unfortunately all the local watchmakers I know won't touch it, apparently they think it's not worth the effort, and everyone I've found online in the US isn't taking new work, so this will be my first "project watch" that is something I actually care about. I'm actively looking around for another 6619 I can practice on since I've never worked on a Seiko before. I'm hoping I can get it running reliably, it currently stops if I leave my hand still for too long with it sitting horizontal. If I'm up and about and walking around it keeps good time.

    Seiko S-261 opinions?

    I'm pretty certain that at least most of the ones I'm struggling with are snap back. The latest rage-inducer is a Seiko 6619-7070, and I've seen pictures of 5's from this era (it's either a 1966 or 1976 based on the serial number, not 100% sure which), and all the ones with screw-backs have case-tool slots, and the ones that don't seem to very clearly be snap-backs. I'd love to be proven wrong though! Here's a picture of a similar contemporary model with the back removed: http://www.klongtonwatch.com/store/product/view/Vintage_Wrist_Watch_Seiko_Sportmatic_5_Water_proof_Diashock_21_Jewels_Japan_made_automatic_6619_8970-26183233-en.html Have you found that a "good" case knife makes a difference?
  13. 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?

    A nice find in the wild

    I frequently visit thrifts for interesting watches and have yet to find any. Congrats on your find!

    What type crystal?

    These would almost certainly be compression fit. If you can't find something that is an exact match to the size you need, err to the large side, and you can sand it down a bit if needed.
