MK Personal Collection Super Rare Rolex GMT Master Peruvian Air Force Wristwatch Circa 1971

MK Personal Collection The present lot is part of a larger privately held collection and is intended for exhibition purposes only. Super Rare Rolex GMT Master Peruvian Air Force Wristwatch Circa 1971. This fine men's steel Rolex wrist watch, Ref 1675, comes in a three piece steel oyster case with a screw down waterproof back. It has a dedicated case back engraved "Fuerza Aerea del Peru" Peruvian Air Force that is signed on the back 1675 II.71 with a light engraving of the case Serial # 3249XXX. It has a Cal. 1570 rhodium-plated 26 jewel automatic movement straight-line lever escapement, free-sprung monometallic balance adjusted to temperatures and 5 positions, self-compensating Breguet balance spring with microstella regulating screws that is in good running condition. It is topped with an original black dial with luminous round bâton and triangular indexes with outer minute/seconds divisions and aperture for the date at 3 o'clock. It is attached to a steel oyster Rolex bracelet Serial # 580 93150 1/76. As the successor to the first GMT-Master reference 6542 with a fragile bakelite bezel, reference 1675 was introduced in 1959 with a more practical metallic bezel insert. The present example has aged in an utmost beautiful way, as the bezel has faded into lovely shades of electric blue and vivd red, and is fitted with a wonderful black matt dial. Adding to its desirability, this example has a military-issued provenance indicated by the "Fuerza Aerea del Perú" engraving found on its caseback. The Peruvian Air Force supplied their employees with Rolex watches based on their rank. As seen in the previous Lot 143, Rolex watches that were designed for the Peruvian Air Force had the full serial number of each watch engraved both in between the lugs at 12 o’clock and on the inside of the caseback.
