Quick TakeThis watch is a rugged companion that feels born for the field, not the boardroom. It has a tangible presence, a piece of over-engineered kit that somehow feels perfectly balanced on the wrist. The bund-style strap is more than just a style choice; it’s a piece of functional history that gives the 44mm case an even more commanding feel, like it's an indispensable instrument. You can almost hear the satisfying mechanical click of the chronograph pushers just by looking at them, ready to time a flight leg or a coffee brew with equal precision. The heart of this beast, the H-21 movement, is a workhorse, storing away 60 hours of energy so it's always ready to go when you are. Looking down at the highly legible black dial, with its bold Arabic numerals and utilitarian sub-dials, it's less about telling time and more about being prepared for whatever comes next. It's a co-pilot for life's adventures, big and small.

DescriptionA substantial stainless steel case forms the housing for the H71706830, featuring a diameter of 44mm and a vertical measurement of 14.15mm. The black dial is shielded by a sapphire crystal, which has been treated with an anti-reflective coating to ensure maximum legibility under various lighting conditions. For enhanced durability and environmental resistance, the design incorporates a screw-down crown, a critical component in achieving its water resistance rating of 10 bar. This pressure rating is equivalent to a static depth of 100 meters or 328 feet, rendering the watch suitable for surface water activities. The case architecture provides a lug width of 22mm, establishing the dimensions for strap integration.

Powering the chronograph and timekeeping functions is the Caliber H-21, an automatic mechanical movement. This caliber is engineered to provide a power reserve of 60 hours, a significant extension that enhances practical usability. A distinguishing characteristic of the movement is the H-pattern decoration applied to the oscillating bridge, a signature of the manufacturer. The watch is secured to the wrist with a calf leather strap, identified by reference H6007171071. It fastens using a 22mm H-Buckle, constructed to match the case material and provide a secure fit.
