Your brief history is a fascinating read, and one very much appreciated by all. It inspired me to do a little research of my own into the history of Rolex COMEX references, the 1665, the 16660 ("triple 6"), and finally the 16600. A succinct discussion of these is available on the Bob's Watches Rolex Blog. Just enter "COMEX" in the search bar and choose "COMEX Sea Dweller Models." However, a subsequent quick look at available examples on the Chrono24 website should not be undertaken without supplemental oxygen nearby! Whoaโฆ These babies are precious! But there you go. Rare commands respect.
