We want to introduce this fantastic example of the original Seadweller reference 1665. Following a decade of two lines of red writing on the dials, the white text was introduced in this format THE MK3 RAIL DIAL! The 1665 dials with the "Rail" are quite rare nowadays since "Rail Dials" were made by the Stern Company who made the 600 meters COMEX 1665 dials and for only 2 years period. 1977-79. (Serial 5 million) Since most people don't like to wear their COMEX watches for daily use because of their collectibility, not to mention because of their high value. Thus, the "Rail Dial"1665 is a perfect substitution for COMEX for everyday use.The Double Red Sea dweller 1665s have spiraled in popularity and value in the last 2-3 years, and possibly it cannot be long before the Rail Dials will follow. The dial is in outstanding condition,The case is strong with even lugs and crown guards.
