The desire to design a watch with a fascinating and useful function but rarely found in a wristwatch, was the inspiration for the creation of the Klepcys Alarm. Faithful to our philosophy of the “Conquest of Innovation” which characterizes all our timepieces, we chose the alarm function and interpreted it by incorporating the typical chime of the minute repeater.

About the Klepcys Alarm

The Klepcys Alarm combines the pleasant sound of a minute-repeater with the useful functionality of the alarm. A complication for everyday life, this timepiece can remind its owner of an upcoming appointment or serve as an alarm clock to start the day.

The secondary dial, between 3 and 6 o'clock, sets the alarm function on a 24-hour scale at 5-minute intervals. This timepiece’s owner only needs to pull out the crown to the first position to rotate the hands, in either direction, to select an alarm time. As the alarm is triggered, the hammer visible at 8 o’clock strikes the gong producing melodic, easily heard notes for a maximum of 16 seconds. To engage or disengage the alarm function, there’s an integrated pusher found on the crown at 3 o’clock. Simple push once to turn the alarm on or off.

This Klepcys Alarm is powered by the in-house, hand-wound CYR1280 calibre with two barrels, ensuring a 72-hour power reserve. For this timepiece, there is an exclusive winding system design, where the barrel placed closest to the balance wheel powers the main time while the second barrel provides the required energy to the sub-dial that activates the alarm.
