Crafted from stainless steel, the 39mm case offers a strong, versatile wrist presence that works well for both casual and elevated wear. The ceramic bezel adds a modern, scratch-resistant touch, while the unidirectional rotating bezel reinforces the watch’s dive-watch functionality. A scratch-resistant sapphire crystal with several layers of anti-reflective coating on both sides helps keep the dial clear and legible.

Applied markers and hands with Swiss Super-LumiNova® improve visibility in low-light conditions, making the watch practical for daily wear and sport use. The date display adds everyday functionality while keeping the dial clean and balanced.

The stainless steel bracelet completes the watch with a sturdy, sporty feel. It is secured with a double security folding clasp and micro-adjustment system, allowing for a secure and comfortable fit on the wrist. At 39mm, this HydroConquest offers a balanced size that feels capable without being oversized.
