Watch Description

I beleive this is a 1970 (N0) Bulova Sea King "BU", cal 10CH, in 14k solid gold. The hands also looked like gold, they had a quality feel, but since they were so pristine, I decided not to scratch test, haha, so unconfirmed. This is the first 10CH I've worked on and it look 100% identical to the 11BL or older 11AL minus the extra material around the mainplate. Outer case serial number is 6676 inner case reference number is L-106. 

If it helps I have the tear down and reassembly video on youtube... https://youtu.be/y0vXH2x9xpA

Yeah, I'll be selling it. It ended up being a lot smaller than I expected. I'll post weight and dimensions tonight.

The rodico is light blue/green, the keyless grease is moebius 9501(I think), and the blue rag in the end is just a clean, dry cotton flannel cloth. I think that covers everything, haha.
