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 Réveil. Faithful to our philosophy of the “Conquest of Innovation” which characterizes all our timepieces, we chose the alarm function and interpret it by incorporating the typical chime of the minute repeater.

About the Klepcys Reveil

The "KLEPCYS REVEIL"  comes with a 42 mm steel case and is distinguished by an atypical interpretation of the alarm function which is reminiscent of the minute repeater chime.  The bell-shaped hammer set between 7 and 8 o'clock is clearly visible on the display with a refined forsted decoration; it strikes to signal the alarm time set on the dial, producing a pleasant sound, for a minimum of 16 seconds. 

With hour/minute, 24-hour alarm and day/night indicator functions, the watch is powered by the in-house manufacture hand-winding calibre CYR1280, with double barrel, offering 72-hour power reserve.
