Ref.16600 is the successor to Ref.16660 and is a third-generation 5-digit reference sea-dweller manufactured from around 1991 to 2009.
The unidirectional black aluminum bezel with hardening treatment on Sapphire crystal, the world's highest waterproof performance of 1220m and the escape valve that automatically discharges helium gas are attractive, but in 2008 Deepsea Ref.116660 Appeared and unfortunately production ended.

The difference from the previous model Ref.16660 is that the movement Cal.3035, which had a single bridge for the balance, has been changed to Cal.3135, which has a twin bridge, improving durability and stability.
