The Blancpain Leman Tourbillon Semainier indicates the day of the week, large date, week of the year and power-reserve indications on a black dial with luminescent index hour markers and Arabic numeral minute markers. It thus incorporates all functions that are useful on a daily basis and meets the demands of an active lifestyle. The new Caliber 3725G, a mechanical self-winding Tourbillon movement with 7-day power-reserve, successfully expresses tradition in modern terms. The strap is made from black alligator leather. Limited edition of 188 pieces and water resistant to 100 meters / 330 feet.
