Signed Rolex, Oyster Perpetual, 660ft=200m, Submariner, Superlative Chronometer, Officially Certified, Ref. 5512, Case No. 1'835'315, Circa 1968

The Rolex Submariner reference 5512 is considered an icon due to its clean and legible look. It, along with the reference 5513, also were a design improvement from their predecessors by adding “crown guards” to help prevent the stem and crown from being damaged by being hit directly against a hard object. The reference 5512 featured a chronometer-rated movement and text on the dial noting that designation whereas the reference 5513 was not rated as a chronometer.

This stunning example has a later dial likely placed on the watch during a service.
