The H-21-Si is an automatic chronograph movement featuring a state-of-the-art balance spring made from the anti-magnetic material silicon for enhanced resistance to extreme atmospheric conditions. With an extended 60-hour power reserve, this powerful caliber reliably keeps and measures time via two or three sub dials at 6, 9 and/or 12 o’clock, and start/stop and reset pushers on the side.
