About this watch

The Longines Hydroconquest Quartz 41 Black / Red is a stunning timepiece that beautifully marries style and function. Crafted from stainless steel, this watch boasts a resilient exterior with a round shape and 41.00 mm diameter, making it perfect for various wrist sizes. The black dial, adorned with vibrant red accents, creates a bold contrast that's hard to ignore. At the heart of the Hydroconquest is the Longines Caliber L115 movement, based on the reliable ETA 955.112, guaranteeing precision with a staggering reserve of 26,280 vibrations per hour. This quartz movement keeps accurate time, eliminating the frustration of frequent adjustments. The dial features Arabic numerals and proprietary hands that glow in the dark, while the date display is seamlessly integrated into the design, maintaining the watch's sleek appearance. The rotating bezel allows you to track elapsed time underwater, making it an essential feature for safe diving practices. With a 0-60 scale, it provides practicality without sacrificing style. The stainless steel bracelet complements its rugged design, and the deployment clasp adds extra security, preventing accidental openings during your adventures.
