The iconic JX1 Chronograph now meets revolutionary comfort with our new EPDM rubber strap option. This evolution of our signature timepiece combines the precision engineering you expect with unparalleled versatility for every environment.

Our AdaptiveFlex Engineered Rubber Strap adds a new dimension of performance—lightweight, flexible, and hypoallergenic, it contours naturally to your wrist while resisting wear, weather, and water damage. It won't crack, fade, or break down, no matter how demanding your conditions.

Driven by the Japanese TMI VD54 movement, the JX1 delivers split-second accuracy with dedicated dials for seconds, minutes, and 24-hour tracking that keep you perfectly synchronized with your day. 

Engineered for action with 100M water resistance, your JX1 Chronograph Sport watch handles rain, sweat, swim sessions, surf days, and surface water sports with unwavering reliability. The scratch-resistant sapphire crystal with AR coating ensures crystal-clear visibility in any environment, protected by our distinctive Diamond Cut Bezel.

This JX1's ShadowLock Sport Clasp ensures the strap tail tucks cleanly out of sight for a streamlined look, engineered with a secure push-button deployment lock that stays put—no matter how hard you go. When light fades but your day doesn't, Swiss Newlite lume illuminates custom hands and faceted hour markers, ensuring maximum readability in low-light conditions.

From workouts to weekends, boardrooms to breaking waves—the JX1 Chronograph Sport keeps pace with your ambition, never asking you to compromise on style or performance.
