I recently won this at auction knowing full well it needed some work.

Issues I have come across so far,
  • Potentially wrong crown/stem. The crown looks to small for the cut out and it sits hard up against the case so you cant push it in any further to set day/date.
  • Only seems to run when the chronograph is running. The balance spring stops when you stop the chronograph.
  • Power reserve is low. I havent worn it more than a few hours but when I took it off it only ran for 3.5 hours before it stoped. It may run for longer had I worn it longer but the seller commented that the power reserve was low.
  • No gaskets. I see you can buy gasket kits on ebay. But I could get them faster and cheaper at a local outlet.
    It seems the gaskets are
    1 x DJ0160B Crown Seal
    2 x DJ0060B Pusher Seals
    1 x FH2980B Caseback Seal
    So DJ0160B is a square cross section gasket of 1.6mm ID. But im confused by the D and J. If its a square cross section shouldn't the width and height be the same?

Firstly, get the SeikoPsycho2 gasket kit. That is easy, top quality, US seller and no work for you to do picking out items.

The low reserve is an old main spring or even partially broken. If you are comfortable swapping with any old 61XX donor that has a decent power reserve that would work

That 'only runs with Chrono running' symptom can mean a clutch issue or worn out Chrono wheel. Maybe even others. Anyway it's in dire need of a service.

Thanks. Some good info there. Although I am looking for a local supply of gaskets. Shipping from the states is probably going to take awhile.

Looks like you have a number of issues going on here both mechanically and cosmetically. Not sure where you are located in the world but as Jon mentioned above Tom ( Seikopsycho2) has complete seal kits and crystals for these watches. Other sources on-line are Adrian at Vintage Time Australia (VTA) and Seikosis. Both are on eBay. Seikosis deals in a lot of aftermarket parts but most are of pretty good quality.

Cosmetically, you might consider luming the hands and dial and replacement of the faded inner rotating ring.

Mechanically, the stoppage issue with the chrono off could be a bad chrono wheel or simply a jewel slightly out of adjustment in the upper chrono bridge not allowing the chrono wheel clutch plates to fully separate when the chrono is disengaged. This will result in stoppage.

The run time reserve issue is likely nothing more than old gluey lubricants throughout the movement needing cleaning and service.

The crown looks to be correct but something obviously going on with the stem. You do not say if turning the crown will rotate the inner rotating ring. If it does not your crown gear and spring are likely missing and will need replacement. These can be hard parts to find. I think Seikosis has a pretty good complete crown and gear assembly replacement. Cost is about $75 US if I recall.

All told, you need to find a reputable watchmaker in your region of the world and have the watch fully serviced. No way of getting around that if you want the timepiece to run properly. Some good smiths here in the US and over in the UK on this forum as well as Adrian at VTA. Good luck with it.

Thanks. Im in New Zealand. There are a few local watchmakers or there is VTA in Australia who seems to specialise in vintage seikos.
Yes the inner bezel rotates with the crown.
I have just checked the watch now and it ran with out stopping over night and lost a couple of minutes. Ill wear it all day and then leave it to run flat.

message him (tom) here on the forum.

also, if you're going to keep that watch for a while, you might consider contacting GuyJ for a reluming of at least the hands or both the hands and dial as they would then match. he can do it so that there is no glowing like a torch. i mention him because he is in the UK and does great stuff.
