The Mark 3 is arguably the most attractive 1675 variant, and being one of the few truly rare Rolex variants, they are often considered “grail” pieces. The dial had marked differences from any other variant, and maximizes legibility as well as utilizing the negative space.
This watch had only one owner, who bought it during his long service in the US Army. Since he primarily worked indoors, he chose the GMT for the 24 hour indication as well as extra luminescence. As a result, the dial, hands, and bezel insert were generally protected from harmful light, as well as the watch overall being protected from the elements. The watch is supplied with an additional case back installed, since the original owner engraved his name on one.
Since this watch was used as a tool throughout its life, it was also regularly serviced, and performs exceptionally (as it should). At least the last two services were done by Jorge Montoya, a former Rolex employee, and highly respected Rolex watchmaker, and documentation from the last service is included. The original owner also purchased a new bracelet for the watch since it was used as a true tool its entire life, and the performance of the piece was paramount, as is also indicated by the service history, and it comes mounted on this 93150 bracelet.
