Blancpain Villeret GMT Date

Blancpain's Villeret GMT Date, reference 6662 3642 MMB, is a GMT watch cased in red gold at 40.5 mm across. The case measures 10.25 mm thick, with a lug width of 22 mm for the Mille Mailles strap. A sapphire crystal covers the opaline dial. Inside is the self-winding calibre 5A50, which delivers a power reserve of 100 hours. Beyond the GMT function, the watch carries a date display and central seconds, useful additions for anyone tracking a second time zone. The strap closes with a folding clasp in matching red gold. Water resistance is rated to 30 metres, enough for daily wear but not for diving.
