Introduced in 1969 the reference 1680 is the first Submariner to receive a date window, thus eventually gaining the official name th♔e Submariner Date. The present example is known to be the "Single Red" Submariner among discerning collectors, featuring an eye-catching red line of text on the bold Submariner logo. In addition, the present example can be identified to be a MK IV dial, features being the "660ft=200m" text placing feet in front of the metres, the "open 6" style 6 text, and the middle stroke of "f" placing lower than the stroke of the "t" on the "ft" text. A supremely attractive example, the present watch carries the charisma of Rolex's extensive heritage and a dial that is turning a nice tropical brown.
