One of the most prominent and recognizable features of Submariner 6538 is its over-sized crown and lack of crown guards. This “big crown” certainly distinguishes this reference from others in the Submariner family and is a feature collectors look for. Ref 6538 utilizes a caliber 1030 nickel-finished lever 25 jewels movement. The brown or black gloss dial prominently features luminous dot, baton and dagger markers as well as luminous Mercedes hands and sweep center seconds. The dial and case are topped with a revolving black bezel calibrated for 60 units. Despite ref 6538 being designated as the “Bond Submariner,” it is more than a movie prop. Rather, it was made in the spirit of the Submariner family and with divers or other water adventurers in mind. The 38 mm tonneau shaped Oyster case features a screw back and large screw down crown, giving it the ability to resist water pressure up to an impressive 300 meters or 1000 feet.
