Amongst Seiko lovers, this watch is the pinnacle of desirable watches. This is a proper diver’s watch, worn by professional divers, and it has a 36,000 bph high-speed movement. And, miracle of all miracles, it’s a Seiko and you can hand-wind it! 😉
Jonathan sent this one in, and, as you can see, it’s in need of quite a lot of TLC.
The luminous compound has come off, and the hands are borderline, but the dial isn’t too bad.
This isn’t too bad, but the movement will get a service as well.
The 6159A movement in all its glory.
The base movement without the auto winder.
As many 36,000 bph movements, this one has a sealed barrel as well, so you can’t just replace the mainspring. As the amplitude of the movement isn’t too bad, and I can’t get hold of a new barrel, I will leave the old one in. You can also see the stop lever for the hacking second feature.
The bottom plate with the date ring. You can see that the escape wheel has cap jewels on both ends as well.And off into the cleaning machine.
I start reassembly with the four cap jewels.
The base movement back together and beating.
After some adjusting, this is looking very good indeed.
David Bill and Sons did the re-luming, and Charles from WatchGlass Cutting in Abergavenny polished the case. Time to put everything back together!
New gaskets all around.
Waterproof testing is well – no pressure loss whatsoever within one minute.
That’s looking a lot better. The bezel ring is a bit scratched and has lost its luminous dot, but I can’t find a replacement.
Charles did a great job polishing the case.
A great looking watch.
