Khaki Navy GMT

The Hamilton Khaki Navy GMT brings together the brand’s military heritage and a practical travel complication, making it a standout in the Khaki lineup. Originally developed to serve globetrotters and naval professionals, this model is prized for its combination of classic American design cues with a true GMT function—ideal for tracking two time zones at once. Its roots in Hamilton’s longstanding relationship with military timekeeping give it a purposeful edge and real-world credibility among collectors.

Reference H77615133 is the most recognized variant, featuring a 42mm stainless steel case, bold dial with prominent 24-hour markings, and a rotating inner bezel for easy second time zone adjustments. Inside, the automatic ETA 2893-2 movement delivers reliable GMT functionality and a 100m water resistance rating, making this watch as capable at sea as it is in the air. Earlier runs featured slightly different dial layouts and hand styles, which can influence collectability and value—later models tend to have improved lume and more refined finishing.

Price variation is driven by condition, completeness (box and papers), and whether the original bracelet or strap is included. The H77615133 on bracelet commands a premium over strap variants, and examples with unpolished cases and crisp bezel action are especially sought after. When shopping, check for smooth GMT hand operation and the correct signed crown, as these are key indicators of originality and proper maintenance for this model.
