Quick TakeThis isn't just a watch; it's a piece of hardcore equipment that happens to tell time. The Belowzero in titanium feels like it was carved from a block of military-grade hardware. Its massive 46mm profile is shockingly wearable due to the lightweight titanium, but it makes an undeniable statement of rugged capability. The four prominent bezel bolts are a declaration of its over-engineered toughness. With a colossal 1000-meter water resistance rating and a beefy screw-down crown, this watch is built to withstand pressures that would crush lesser instruments. The stark, functional grey dial is a lesson in legibility, with massive numerals that blaze to life in the dark thanks to a heavy application of Super-LumiNova. Inside, the H-10 movement’s impressive 80-hour power reserve means it’s ready for a long weekend mission and will still be running on Monday. The vibrant yellow strap isn't just a style choice; it's a high-visibility signal that this watch is a serious tool for serious adventures.

DescriptionThe H78535380 is engineered with a substantial 46mm case diameter, fabricated from lightweight and durable titanium. Its vertical dimension measures 15.7mm in thickness, contributing to its commanding presence. The dial is protected by a sapphire crystal, enhanced with an anti-reflection coating to ensure maximum legibility under harsh lighting conditions. Water integrity is paramount, rated to a depth of 100 bar, equivalent to 1000 meters or 1450 psi. This is further secured by the inclusion of a screw-down crown mechanism. The grey dial features hands and indices treated with Super-LumiNova for optimal visibility in low-light environments. The lug width is a standardized 24mm, accommodating the supplied rubber strap.

At the core of this timepiece operates the Caliber H-10, an automatic three-hand movement. This mechanism provides an extended power reserve of 80 hours, a significant increase over standard automatic movements. The incorporation of a Nivachron balance spring enhances the movement's resistance to magnetic fields and temperature variations, ensuring greater timekeeping stability and precision. The timepiece is affixed to the wrist via a yellow rubber strap, identified by the reference H6000001971. This strap is secured with a titanium H-Buckle that has a width of 22mm, providing a secure and comfortable fit for the wearer.
