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.
Original condition case in excellent condition. Thick lugs with sharp original bevels on the edges. No marks or surface scratches can been seen.
Original tritium dial in excellent condition with matching tritium hands and original tritium pearl.
Comes on a solid link 91350 bracelet with 580 end pieces. 12 links with little to no stretch.
