The Oyster Perpetual Air-King pays tribute to the pioneers of flight and the Oyster’s roles in the epic story of aviation. It is crafted in a 40mm Oystersteel case complimented by a smooth bezel. The black dial features a combination of large 3, 6 and 9 numerals marking the hours and a prominent minute scale for navigational time readings. The watch comes on a steel oyster bracelet with an Oysterlock folding clasp.
