Description

The Promaster Sky U830 is a chronograph designed for performance and style, built with aviation inspired functionality and bold character. The 43mm black tone stainless steel case is paired with a sharply finished triple link bracelet, while the rotating slide rule bezel, modern pushers, and crown add to its refined sport aesthetic. Beneath the scratch resistant sapphire crystal, the black dial combines analog and digital displays accented in white, creating a striking balance of design and technical precision.

The watch offers a range of advanced features including analog digital timekeeping, a perpetual calendar, an alarm, a 1/100 second chronograph that measures up to 24 hours, and a 99 minute countdown timer. Powered by Eco-Drive, it converts light into energy and never requires a battery. The watch is water resistant to 200 meters, ensuring durability and reliability in everyday use as well as more demanding environments. At its core is Caliber U830, delivering accuracy and advanced timekeeping performance.
