Quick TakeStrapping on the Khaki Field Expedition feels like gearing up for an adventure you did not know you needed. Its clean, white dial offers an immediate, no-nonsense read, a blank canvas for the day's story. The 37mm case is a sweet spot, a classic size that is all business and no bulk, hugging the wrist comfortably whether you are navigating city streets or an actual trail. That bi-directional bezel is not just for show; it is a tangible link to exploration's golden age, a tool ready for impromptu solar navigation. Beneath that ruggedly handsome exterior beats the H-10 automatic movement, a powerhouse with an 80-hour reserve. You can set it down Friday and find it still ticking Monday, ready for the next mission. It is a watch that does not shout for attention but earns respect with its quiet confidence and solid build, from the sapphire crystal to the screw-down crown.

DescriptionThe case of the H70225510 is constructed from stainless steel, featuring a diameter of 37mm and a thickness of 11.45mm. Protecting the dial is a scratch-resistant sapphire crystal, which has been treated with an anti-reflection coating to ensure maximum legibility under various lighting conditions. For enhanced durability and water integrity, the watch is equipped with a screw-down crown. Its water resistance is rated at 10 bar, which is equivalent to a depth of 100 meters or a pressure of 145 psi. The design also incorporates an open case back, offering a view of the internal mechanical movement. The lug width measures 20mm, accommodating the supplied strap, and the case is topped with a bi-directional rotating bezel marked with cardinal directions for basic navigation.

At the heart of this timepiece is the Hamilton Caliber H-10, an automatic three-hand movement. This mechanism provides an extended power reserve of 80 hours, a significant duration that allows the watch to remain operational for over three days without winding. The movement's precision is enhanced by the inclusion of a Nivachron balance spring, known for its resistance to magnetic fields, temperature variations, and shocks. The white dial is designed for clarity, with hands and Arabic numeral hour markers coated in Super-LumiNova for visibility in low-light environments. The watch is fitted with a cow leather strap (reference H6000001561) that fastens with a stainless steel pin buckle. The buckle width is specified at 18mm.
