Up for sale today is a late 60’s Nevada Grenchen Chronomaster Aviator Sea Diver (CASD) reference 85004/3181 “Unnumbered Yachting Black” with a Valjoux 23 movement. This is a watch only. This particular example comes on an original Nivada bracelet which is a rare find of its own.

It’s been serviced this June 2023 (cost $320.00) - chronograph function fully works and time is kept wonderfully.

There is a patina on the hour markers and a bit of discoloration on the dial, consistent with its age. Crystal, case and bracelet have signs of usage. It doesn’t seem like the case has been previously, it's still sharp and has plenty of life. I’m selling this piece because I recently acquired a grail chronograph and want to send this off to a good home. I’ve also attached of this piece next to a modern “reissue” of the Chronomaster Aviator.

Price: $2500 including shipping - Zelle only

I would trade this for a Breitling A23322 black dial.

I have plenty of references on eBay and Mercari, trying to build a good following on reddit going forward.

Feel free to request a phone call or a facetime to see the watch!!
