The Hamilton Khaki Field King Auto H64455523 pays tribute to Hamilton’s proud military heritage with a bold design that emphasizes legibility, strength, and endurance. Featuring prominent military time markers on its beige dial, the watch blends rugged field-watch functionality with refined craftsmanship, making it an ideal everyday companion.

At the heart of this timepiece is the Hamilton H-40 automatic caliber, an upgraded movement offering an impressive 80-hour power reserve—nearly double the industry standard. This means the Khaki Field King can be set aside for the weekend and still be running on Monday, ready to go without interruption.

The 40 mm stainless steel case strikes a balance between robust durability and modern wearability. Protectors have been specially designed around the crown to safeguard it during daily use, reinforcing the watch’s utilitarian roots. With a thickness of 11.15 mm, it sits comfortably on the wrist without sacrificing presence.

The beige dial features crisp Arabic numerals, a day-date display at 12 o’clock, and Super-LumiNova®-coated hands and markers, ensuring excellent visibility in all lighting conditions. Its sapphire crystal adds superior scratch resistance and clarity.

Flipping the watch reveals an open case back, offering a view of the finely decorated movement—a detail that reflects Hamilton’s balance of ruggedness and sophistication. Water resistance up to 5 bar (50 m) makes it resilient to daily exposure.

Completing the design is a brown cow leather strap with an 18 mm pin buckle, offering both comfort and vintage-inspired style. The 20 mm lug width ensures compatibility with a wide range of replacement straps for versatility.
