Citizen Promaster Sky JV2000-51L Men's Watch • Eco-Drive Sapphire Crystal • Pilot Chronograph

The Citizen Promaster Sky JV2000-51L is a technically outstanding men's wristwatch that combines pilot aesthetics with cutting-edge Eco-Drive technology. The solid stainless steel case, measuring 43 mm in diameter, houses the newly developed in-house calibre U830 – a combination quartz movement featuring a high-resolution MIP (Memory-in-Pixel) display. The blue dial with crisp baton indices is protected by an anti-reflective sapphire crystal and radiates the unmistakable character of the SKY line. Thanks to Eco-Drive, the watch runs without ever needing a battery change, powered solely by light.

Calibre U830 offers an impressive range of functions: world time across 43 time zones, chronograph, two alarm times, perpetual calendar, automatic hand correction, and a power reserve indicator. The power reserve stands at 360 days in normal operation and up to three years in dark mode. A slim slide rule bezel and lugs reminiscent of aircraft wings complete the classic pilot design. The silver-toned solid stainless steel bracelet is secured by a reliable double push-button deployant clasp. With water resistance to 20 bar, this watch is well equipped for a wide range of activities.
