勞力士，不銹鋼自動上弦鏈帶腕錶，配中心秒針及日曆顯示，“Submariner”，型號1680，約1974年製

Introduced in the late 1960s the reference 1680 was the first Submariner to feature a date indicator as well as the cyclops magnifier. Distinguished by its red printing to the dial, the “Red Sub” as it is known to collectors has become a cult classic.
