I have a Citizen Eco Drive Proximity watch (it has Bluetooth) with the W760 movement which does not seem to be working.  I've had it operating in the past with charging at least well enough to tick and set the time; I let it discharge from not exposing to light for a while and tried to get it to charge and only got the low battery 2sec ticking.  Removed the battery, measured the voltage which was  between 2.6 and 2.7 volts, which I thought should be enough for proper operation.  I reassembled the watch and now it doesn't tick at all.  There is only one way to properly insert the battery.  Anybody out there ever deal with this movement or the similar W770?  Citizen won't sell parts and just suggest sending it to them (for what in my experience has been rather expensive prices for the worth of the watches) so I'm buying a battery for it off Ebay.  Maybe it's the cell.  Otherwise it'll probably be experimental for my watchmaking abilities!  Any help or suggestions?

Thanks for the replies!  It is amazing how long it takes to fully charge the watch even in bright sunshine!  A miracle has occurred!  I got out my regulated DC power supply, set it for 3.6 volts and 8ma and actually charged the battery manually.  It's a 3v Maxell which has 2 horizontal "ears" 180 degrees away from each other which locates the battery in its niche  and 2 vertical "ears" which actually conned the (-) to the movement.  Once I got above 2.8v I reinstalled the battery, felt a vibration, then the watch worked!  Again thanks to the responders.

      Seitz Tool - Help determine if Seitz or not

      By ManSkirtBrew · Posted

      Right now I'm making do with a similar micrometer (the one below is $45 shipped but you can find better deals) and a $20 stand. You do have to be excruciatingly careful measuring jewels, since there's no table, but if you don't have the $500 to throw around, it's a nice option.

      As  I kid, I'd watch Godzilla stomping over buildings and cars and I'd think to myself: Tokyo is a really dangerous place to live... . Cool watch!!

      Next one up an AS 554, looks like a bit more to this one. First job is to check thickness, most springs are somewhere between .3 and .4, this one measures .35, that matches in with the .4 spring steel i ordered. So for marking up a permanent marker comes in handy to colour up the steel to be marked later with a scriber once its dry. Bestfit provide the extra bit of info for the jumper spring that is missing.

      Thanks again, Marc.  Super helpful. I was wondering what the hole was for, and now it makes perfect sense. With your help and the other members here, it looks like I'm good to go with my Seitz tool set. I had to order some replacement pushers, but with those, the set is complete and in good condition. Now, I need to figure out what tool to buy to measure jewels (amongst other watch-related parts). I had my eye on the JKA Feintaster micrometers, but people get crazy bidding on them for $400-600 USD. I was thinking of just a regular digital micrometer (Mitutoyo). Thoughts?  Mahalo. Frank

      Yep, that's exactly how it should fit. The reamer shank is tapered and the socket in the spindle is also tapered so that the one centers in the other and is gripped tightly. If there is any wobble when the reamer is seated as far it will go then there is a problem. The cross hole in the spindle is to allow you the push the reamer back out again. If the reamer seated much deeper then it would limit the access for pushing it back out again. Here is one of mine for comparison.
