The first Submariner Date to feature the now iconic "ft first" dial, this 1970 ref. 1680 Submariner sports the famous bright red signature that gets collectors excited. The distinctive wide open sixes identify it as a Mk IV dial, that tallys perfectly with the 2.63 million serial number, and the chunky case is in lovely condition with nice wide lugs. Serviced by Rolex UK in June 2006, where they supplied the sturdier 93150 Oyster Flipolock bracelet currently fitted.
