1964 Rolex Submariner (Ref. 5512) GILT

The Rolex Submariner Reference 5512 is the embodiment of the classic dive watch. The 5512 is simple yet sophisticated and rugged whilst becoming increasingly more uncommon and collectible. Ref 5512 was first introduced in the 1958 and ceased production in late 1978. The 5513 was introduced a few years later in 1962 and was in production till 1990.

The Ref. 5512 like the Ref 5513 is a purpose-built dive watch that lacks the date function like other Rolex Submariner models. (eg. Ref. 1680.)  The main difference between the Rolex Submariner Ref 5513 and Rolex reference 5512 is the caliber of movement within the case. The Rolex Submariner 5512 and Submariner 5513 started both out with the Rolex caliber 1530 movement but the Rolex Submariner Ref 5512 later on was equipped with a chronometer certified caliber 1560 and 1570 movement, bearing the chronometer writing on the dial above the 6 o'clock position AKA the 4 lines of text as opposed to the non-chronometer certified 2 liner dial's of ref 5513's which is the easy and main way to tell the difference between the 5512 and 5513 references of no date matte dial submariners

This specific example from 1964 is joining the ranks of the more collectible. It said that for every five 5513 made in the 1970s one 5512 was made.
