Hamilton Khaki Navy Frogman 46mm H77825330 mechanical automatic, with Caliber H-10 providing up to 80 hours of power reserve.

The polished and satin-finished stainless steel case has a diameter of 46 mm, perfect for those involved in water sports that require wetsuits.

Press-fit closed back with laser-drawn Frogman logo.

The black dial provides excellent visibility, partly because of the lumibrite-coated markers and hands for viewing in the dark. The indexes are all in relief from the base.

The crown at 3 o’clock features special water protection. To adjust the time, simply unscrew from the case and pull out the crown, as is usual with other models.

Black unidirectional dial for dive time adjustment.

A rubber strap with a pin buckle makes wearing this decidedly sporty watch easier and lighter.

Waterproof up to 30 bar/300 meters.

Anti-reflective treated domed sapphire crystal.

Watch accompanied by official Hamilton box and warranty.
