    Wanted to share my latest project that's currently in progress. I've had such great guidance and help from this forum, it felt right to share the fruits of that learning! Picked up a 6139-8029 for a good price on eBay (around $140), but had no clue what was inside. Fortunately, the 6139B...

    Hi all, for sale is my very nice 1975 Seiko 6139-6002. This one is in very nice shape. It has been serviced and the case and bracelet were refinished in the last 2 years. When I say refinished, I don't mean polished, which would round the corners, but rather sharpened and re-brushed to return it...

    Hi all, I'm looking for some Seiko 022459 screws that attach the winding bearing framework on a 6139B movement. Finding these screws seems to be very tough. I would appreciate if anyone has some in their stash that would sell! Or can point me to what would be a suitable replacement; perhaps a...

    Hi all, I’ve got a lot of vintage Seiko and Citizen models for sale. All are running, unless otherwise noted. I acquired these as a lot so I have no further knowledge of owner history, service, or replacement parts. Shipping is included in price for U.S. addresses. If you have additional...

    Having trouble digging up a parts list for the 6139-6022 "Pulsations", but I believe that the original parts number for the crystal is the 350T02ANS. Is this correct?

    I've recently come into possession of two good examples of the Seiko 'White Helmet'. The first is dated December 1975, reference 7100. The second is dated September 1978, reference 7101. It took me a little while to spot them, but there are differences between the two cases: 1. On the 7100...

    I have to share again the great work that Simon does, this time on my 6139-6000. There was much more water intrusion than there appeared to be when I got it from an estate dealer with a missing crown/stem. These are always risky when the crown is missing and the lume shows that water has been...

    I recently had a auto chrono appreciation week (well, I wore them last week ;) ), so I thought let's get the band together for a photo: Seems that I am light in the Daini department... Although two 7018 are missing - they require service.
  18. Mod & Restoration Reviews (Mod/Restored Watches)
    I have a 6139 in pretty good shape, putting a new crystal on, putting on a metal bracelet and trying to make the watch look new-ish. I see the dials for sale on ebay and wonder if these are as indicated or look sort of goofy and cheap from the get-go. I don't ever intend to sell the watch...

    Hi all, I'm taking my Seiko 6139 - 6000 in to a local watchmaker (Shane Ede in Toronto for those who know), and I'm wondering what I should be asking him to do for me. I'm taking it in mostly to have the crystal replaced with a New Old Stock genuine crystal because as you can see the current...
