Hamilton American ClassicIntra-Matic Auto Chrono 40mm Unisex Watch Black

Ref. H38446731

A 40mm black PVD-coated steel case houses a matte black bi-compax dial with yellow hour markers, a vivid yellow chronograph seconds hand, and Super-LumiNova on both hands and applied indices. The layout places small seconds and a 30-minute counter in two subdials, with a date window at six o'clock and a tachymeter scale around the perimeter. The slightly domed sapphire crystal carries double-sided anti-reflective coating. Inside sits Hamilton's H-31 automatic calibre — a 27-jewel movement beating at 28,800vph with a 60-hour power reserve and a Nivachron balance spring for magnetic resistance. A black perforated calfskin strap with yellow detailing beneath fastens via a black PVD pin buckle, and a screw-down crown supports 100 metres of water resistance.
