The Blancpain Villeret Demi-Fuseau Horaire is one of a select number of travelers watches that is able to adjust to half time zones; the main time can be adjusted in 30-minute steps without affecting the reference time at 12:00.

Reference 6661-3631-55B has a case in red gold and a white grand flinqué enamel dial. The case back is fitted with a hinged cover protecting the see-through glass.


Blancpain caliber 5254DF Self-winding movement with second time zone, day/night indicator, power reserve indicator and date.

It displays the reference time at 12 o’clock, the half-hour timezone in the centre, the day/night indication for the reference time at 9 o’clock, the date – which changes in step with the second timezone – at 6 o’clock, and the date change or timezone indication at 4 o’clock.

With this movement it is possible to adjust the second timezone on the watch in 30-minute increments and thus to ensure relaxed travel to countries with half-hour time differences. A pusher located on the head of the crown serves to select fast date correction or half-timezone adjustment mode. Correcting the reference time automatically modifies that of the second timezone. It is worth noting that the date correction is fully secured to avoid any risk of damage.
