Rolex Submariner Date Ref.1680
Introduced in 1965, the Rolex Submariner Date Ref.1680 was the first watch in Rolex Submariner history since 1953 to have a date display. The Submariners with no date displays are called “non-date” and they were sold along with the Rolex Submariner Date during the same time.
The production period was from 1965 to 1980 and it’s successor model, the Rolex Submariner Ref.16800( 2nd version of the Date model) was born.
The specifications of the watch include a self-winding chronometer Cal.1570 and a hack mechanism that stops the PRE-OWNED when the crown is pulled out.
The Cal.1570 chronometer is a type of movement famed for its with low-maintenance and durability installed on Rolex flagship series watches such as the Explorer Ref.10116 and Datejust Ref.1601.
At that time, with its plastic windshield and waterproof performance of 200m, the next-generation model Rolex Submariner Date Ref.16800 (2nd version of the date model) was equipped with a sapphire crystal windshield, thus upgrading itself to a 300m water-resistant watch.
Among the Ref.1680 watches, the Red Sub with a red 'Submariner' logo is will be the main focus of today.
