Rolex Submariners (date)
................
-under construction-
The following information and photo contributions by Mike:
The 1680 made it's debut circa 1967 with the RED meters first dial.
Latter REDS with feet first began circa 1970,
Hacking is generally felt to have been introduced in the 70 to 71 timeframe as Rolex brought the modification on line, but some crossover exists.
1970 RED 2.5 mil. NON-HACK
Most collectors shy away from REDS over 4 mil.
Additionally, FEET FIRST dials had several different style fonts,
Note: Photo credit Bernard,
1970-72ish, opens 6s
72-73ish, semi-open--NOTEWORTHY, some feel these were Beyeler dials made in the 3 to 3.5 mil range,
73-74--closed 6s
The white came circa 1975 though many have noted finding one in this serial number range is a challenge. Some speculate the 1680 was made in very few numbers from circa 75-77 for what ever reason.
Most seem to fall into a serial number range after 77-78.
Mine, both 5 mils, circa 1978-79,
A luminova replacement dial,
May I also submit the reference 16800?
Making it's debut circa 1979-1980, the reference 16800 introduced several new features.
The first diver to have a 3035 fast beat movement. It also was the first to feature a true quick-set date, uni-directional ratching bezel, sapphire crystal, metal pearl cup, and of course an increased depth rating to 300 meters.
Early versions had a matt dial sans WG surrounds, while later versions came with a gloss dial with WGs (circa 1985)
Mine circa 1980,
