I really like this watch and won’t be disappointed if I end up keeping it, but have a potential incoming and need to cull the herd (just a bit). Is it actually culling if you replacing it? Anyways I digress, here is a Coke 6139-6032 from May 1971. I bought it from an older gentleman who said he bought it from the original owner. Apparently the original owner bought it on R&R in Japan during the Vietnam war. The original owner was also enthusiastic about engraving his social security number on the bracelet and case back although it isn’t distracting to me and is not too aggressive. I’ll include the original, hard to find bracelet, although it’s missing one end-link. So I will also include the second hard to find JDM bracelet that has its end links. The guy I bought it from claims it was serviced a few years ago and it appears that this may be a replacement crystal. But there is no receipt for said servicing so I would assume it could use another one. That being said, it keeps time well but the chrono pushers are soft (something I’ve found in quite a few 6139s). Date wheel is English/Kanji. Otherwise it appears to be original to me but take a close look at the pics as many others are more astute to vintage Seikos. The price is $850 and PayPal is accepted from established members, but the fees are on you if you want to use goods and services. Free shipping for CONUS or FTF in Washington, DC area. International shipping at buyers expense. It will come with the two bracelets but not the leather strap as seen in the one pic. Thanks!
