This is a hands-on look at manufacture Christophe Claret’s newKantharos mono-pusher chronograph with a striking mechanism and constant force escapement.

The automatic-winding chronograph’s cathedral gong audibly chimes with each change of function: start, stop and reset. A constant force escapement, visible at 6 o’clock on the dial, ensures the energy delivered to the escapement remains constant from the beginning to the end of the power reserve.
