Blancpain Villeret Tourbillon 8 Jours

Blancpain's Villeret Tourbillon 8 Jours, reference 6025 3642 55B, is a men's model with a 37.5 mm red gold case. The case measures 10.4 mm thick, with a lug width of 20 mm suited to the alligator leather strap. Self-winding calibre 25 drives the watch and stores enough energy for an eight-day power reserve of 192 hours, shown on its own dedicated display. The opaline dial sits under a sapphire crystal and carries a central seconds hand and a date function. The tourbillon regulates the movement and is visible through the case, a detail that anchors the watch firmly among Blancpain's high complications. A folding clasp secures the strap to the wrist. The case is water resistant to 30 metres, modest by design given the dress proportions of this piece.
