I recently serviced this pristine vintage Seiko Kakume 6138-0030 chronograph for regular ClockSavant customer. Most folks have seen the very nice blue dial version of the Kakume, but this silver dial version is also a sight to behold-- Seiko was at the top of their design game with these watches. Like many watches I service, this one had been subjected to "spit-job servicing"-- someone did a few things here and there, dumped oil and grease around, and left their fuzz and hair behind. After full servicing, this watch is now running beautifully again. One item of note was the original bracelet. I know Seiko collectors like them, but the fact is that these bracelets are old and worn and can often have high-risk wear and corrosion as this one did. You risk losing your watch and entire investment if you wear a vintage bracelet that is not sound. The same goes for the spring bars. So check your bracelets for soundness and corrosion regularly. In this case, the watch will be mounted on some other bracelet as the vintage bracelet was no longer suitable for use.
