Offering function-based design at its most successful, the Big Crown ProPilot collection is full of pioneering timepieces aimed at pilots who value its cockpit-ready functionality and aesthetic. This Big Crown ProPilot is the world's first automatic mechanical timepiece with an integrated barometric altimeter, an instrument that measures altitude with the help of atmospheric pressure. It features a 47 mm multi-piece stainless steel case with dual screw-down crowns and a distinct coin-edge bezel that holds a matte black dial under a double-domed sapphire crystal. It has white and luminescent obelisk hands, white Arabic numerals and indices as hour markers, and a date window within the central dial. The altimeter with feet scale is printed along the sloped flange followed by a recessed atmospheric pressure scale, calibrated and set via the oversized crown at the 4 o'clock position. Hovering along the recessed space is a yellow indicator for altitude and a red indicator for air pressure. It is fitted with a black leather strap on a security folding clasp which interestingly resembles an aircraft seatbelt. Encased within the specially engraved solid caseback is the Oris caliber 733, a Swiss automatic movement beating at 28,800 vibrations per hour, generating up to 38 hours of power reserve, and is water-resistant up to 100 meters/330 feet.
