Quick question for the Seiko experts. I'm starting a basket case 6139 restoration project. I'm trying to source a crystal and bezel. Can you point me to the best place? Just trying to get it up and running for personal use. Not trying to make it perfect. Any help is greatly appreciated

 

You should be able to get a crystal from Spencer Klein

Bezel may be harder, maybe Speedtimerkollection?

 

Try Ebay to see if you can source an original bezel. Seiko made a ton of these watches so parts are definitely out there.

 

The part number for the crystal as you have probably worked out is either 330W18GN or 307V02GN. The former is more commonly recreated, as someone else mentioned, Spencer Klein does some as do others.
There is a lot of discussion here:

I haven't seen NOS Seiko recently, but there are probably Yoshida and other manufacturers that were suppliers to Seiko available here in Japan at a price.

I have a 6139-6010 Bruce Lee myself with the blue dial. Got a NOS set of hands but these are the original and matt which were only on the earliest models, so decided to stay with them for now.

What is your case number on the back? I am not sure about bezels, but aftermarket bezel inserts are plentiful.

 

I'd recommend a Sternkreuz aftermarket crystal, tbh - they're great. £22 from Cousins UK Special Profile, Sternkreuz XMD (cousinsuk.com) or you can get them on eBay etc. As for bezels, they're 10-a-penny on eBay and a straight push-on fit. Do watch out for aftermarket ones in case you're after an original. Hint - look at the 140 and the placement of the stroke, as a tell-tale for a lot of fakes (ie the low point of the stroke should be between the 1 and 4, and if you drew a line across between the tip of the 1 and 4, the stroke would intersect it). Lots of AMs have a misaligned stroke which is higher than both the 1 and 4...
