Hamilton Khaki Navy Scuba Auto GMT 43mm Blue

The 43mm stainless steel case is rated to 300 metres, secured by a screw-down crown. A sapphire crystal with anti-reflective treatment protects the dial, and the unidirectional rotating bezel carries a 24-hour ceramic insert in matching blue for tracking the second time zone.

The dial is finished in a deep blue fumé — sunburst at the centre, darkening toward the rhodium-coated edge — with broad Super-LumiNova-filled indices and a red-tipped GMT hand for contrast. A date window sits at three o'clock.

Calibre H-14 is Hamilton's automatic GMT movement, fitted with a Nivachron anti-magnetic balance spring and delivering an 80-hour power reserve.

Mounted on the matching stainless steel three-link bracelet with folding clasp.
