Blancpain Villeret Tourbillon 8 Jours

Blancpain's Villeret Tourbillon 8 Jours, reference 6025 1542 55B, has a 37.5 mm white gold case. The case measures 10.4 mm thick, with a lug width of 20 mm. A sapphire crystal covers the opaline dial, which carries central seconds and a date display. The self-winding calibre 25 drives a flying tourbillon and a power reserve display, with an eight-day autonomy of 192 hours confirmed on the dial itself. The case pairs with an alligator leather strap on a folding clasp. This is a tourbillon watch built for precision timekeeping over its extended reserve rather than daily robustness. Water resistance is rated to 30 metres, enough for accidental splashes but not for swimming.
