Moritz Grossmann · HAMATIC Enamel
The movement in detail
A conventional automatic calibre draws energy from a rotating rotor. In the HAMATIC, an elongated hammer swings above the bridges: wrist motion sets it moving, while a transmission with ratchet elements directs energy to the winding barrel. The energy source is the same — the wearer’s movement — but the architecture is markedly different. The HAMATIC name itself refers to the hammer.
The manufacture 106.0 consists of 312 parts, beats at 21,600 semi-oscillations per hour, or 3Hz, and runs for 72 hours when fully wound. It has 38 jewels, adjustment in five positions and hacking seconds. Manual winding is also provided. This is useful after the watch has been left unworn: the swinging hammer does not remove the need to build energy in the spring first.
