The Aviation Collection is an homage to the genesis of the Pilot's Watch. The Aviator Chronograph uses subtle details, blending colors and texture to update the classic style without compromising the utility of the original pilot's watch. The 42mm case is comfortable for everyday wear and features an easy-to-read dial with SuperLuminova markings and applied indices. The interchangeable straps allow the Aviator Chronograph JM-A102-203 to evolve with you. As a subtle homage to the Texas flag, the second hand is hit with a subtle red, white and blue marking. The crown is etched with a Texas lone star as an homage to Jack Mason's roots. The watch is water-resistant at 10ATM for comfortable wear when exposed to water. The screw-down case back is etched with aircraft propellers for a final hat tip to the aviator aesthetic.
