Description: 1978 Rolex 1665 sea-dweller. Excellent collectors grade 1665 with lightly polished case. The 1665 reference was the first dive watch to feature a helium escape valve. This allowed the comex divers to dive to further depths and resurface without fearing their crystals popping off due to helium gasses not escaping. Excellent super dome crystal. Patina on the lume is nice even custard.
Dial: Matte-Dial Small ft MK 1 dial
Insert: Faded grey Fat Font Insert
