Seiko case backs

[LonglineOjoe]

Good day to all!  Would anyone know where I could source case backs, specifically Seiko (6138-0040 and 6139-7100), beside eBay?  The few I can find are priced astronomically and the shipping is more than the part!

https://speedtimerkollektion.com/ is a good source of parts for Seiko you will just have to keep looking, both the watches you need backs for are very collectable now and demand high prices so I doubt any one would sell any case parts for them cheap.

Hi Try  osoleteclockandwatchparts.co.uk I have picked up a few seiko bits from him. Its run by John senior in Yorkshire.

Post a WTB on SCWF and Wristsushi . Have some 6139 case backs. But no 7100 . 6138 cases i have seen on Ebay . Or buy a donor watch .

i personally think ebay is the best source, speedtimerkollection doesnt always have the harder to find case backs like the ones you mentioned and I highly doubt they will have a bullhead case back.

I have found a .more  than fair amount  of case back swapability with seiko.  From what I can tell the shape  of the back is dependent  on the type of rotor. Unless that  case back is an absolutely  must have,one from a watch with the same movement  may work until  a match can be found.

Thanks everyone!  I checked out those sites, a lot of parts but, as you all say,  no case backs for those two. I’ve tripped swapping another 6139 back to check the fit (thanks @yankeedog) and it seems to do the job!  I’ve got a few shipment’s off watches coming to me in the following weeks ( yes, I have a serious problem and a depleted credit card .) so o should be able to use some of those pieces.

That is because the Seiko design and manufacturing mandate the largest possible no. of common parts for wattches using the same or similar caliber.

listen be patient and wait for the correct case back for the bullhead. those watches are going up in value every year, they sell for $600+ now.

That for a mediocre one  The desirable ones go for much more.

Will be Seiko able to make a faithful reproduction? It depends on what one calls faithful, if you accept that current 8L35, 6R15, 4R36 based reproductions of beauties of the past are, then there are (remote) chances they will. But they will never, ever go back making the great mov'ts of the past. Well, not even Omega and other big brads do.

i believe the repros are overrated, works of art indeed but overrated. One thing i do like is they boost the value of the originals. i.e. the H558 Arnie and the 6105 and 62mas. I purchased 2 6105s in 2017 for $800 and $900. One of them was like NOS with box. I was waiting since 2018 for the re-release since it was the 50 year anniversary, I had a feeling a repro was coming but couldnt wait anymore and sold the one for $1000 last year on watchuseek because I wanted to move on to another watch and i kept the nice one for myself. I sold right before the announced the release of the 6105 i was so pissed. know you cant find a decent one for less than $1500. I saw few sell for $2000+ esp if the serial number is dated pre-1972 during the vietnam era. And Iam not selling mine its a 1971 and its mint all original with box i could prob get 2500 for it but i just cant part with it. And it makes sense because why pay $4000 dollars for a watch when you can buy the original for half, and the same goes for the 62mas, and the 6159.

I agree, I want a little experience on my watch!  I have no desire to get a new sparkly one yet:).
