1665: This is a gorgeous example of a very complete 1665 Sea-Dweller with the "transitional" case back. Instead of the normal round case back, this watch bears an outside engraving more similar to the 16660 SD which was produced concurrently in the early 1980s, marking the end of the 1665 and the beginning of sapphire crystal SDs. Rarely seen, this is a great example of an uncommon variation.
