The watch’s GMT or “Double Timezone” function uses a center-mounted, blued serpentine hand (a Blancpain hallmark) to indicate the time in a second time zone on a 24-hour scale; the numerals 1 through 24 are on an inner ring beneath the dial’s applied Roman hour numerals I through XII. The gold hour and minute hands display the current local time. In addition to the mechanical alarm and GMT complications, the watch features a date display (in a window at 6 o’clock) and a power-reserve indication (between 10 and 11 o’clock). The Blancpain Villeret Reveil GMT has a 40.3-mm-diameter case (12.1 mm thick) in either 18k rose gold or stainless steel. It is water-resistant to 30 meters and has a clear sapphire caseback. Its timekeeping and other functions are powered by the Blancpain manufacture Caliber 1240H, a self-winding movement with a silicon balance spring and a power reserve of 45 hours. The movement measures 31.7 mm in diameter and 6.20 mm in thickness and contains 392 components, including 36 jewels. As in other Blancpain watches with alarm functions, the movement is equipped with two barrels — one for supplying energy to the movement, the other to store energy for the alarm’s striking mechanism. Caliber 1240H’s automatic winding system winds them both simultaneously. The watch is available on an alvazel-lined alligator strap with a folding clasp or a “Milanese” mesh bracelet in either steel or gold.
The Blancpain Villeret Reveil GMT in steel is $24,700 on a strap and $27,000 on a bracelet; the rose gold model is $36,400 on a strap and $55,700 on a bracelet.
This is similar to Breguet’s Reveille du Tsar. Almost identical.
