Blancpain caliber 1241
Self-winding movement with an additional, adjustable 24-hour indicator, alarm, power reserve indicator, and an on/off indicator for the alarm.
A 12-hour counter with two hands, positioned at 3 o'clock, displays the time programmed for the alarm. Pressing the push-piece at 8 o’clock activates the alarm by engaging a column wheel. An “On/Off” indicator at 1 o’clock shows at a glance whether the alarm is activated or not. The chime is produced by a hammer striking a gong. The automatic winding system winds both the movement and the alarm power reserve simultaneously.
