Hamilton Khaki Field Mechanical Bronze

The Hamilton Khaki Field Mechanical Bronze, reference H69459510, has a 38 mm bronze case water resistant to 50 metres. Under a sapphire crystal, the white dial carries central seconds. Hand-wound calibre H-50 keeps an 80-hour power reserve and regulates with a Nivachron balance spring. The 9.6 mm thick case is on a calfskin strap with 20 mm lugs and a pin buckle. Environmental exposure gradually develops an individual patina on the bronze.
