The caliber UNICO HUB1241 features an automatic column wheel chronograph with a flyback function which allows you to quickly reset the stopwatch feature without having to stop, reset, and restart the timer again.

The Hublot UNICO HUB 1241 movement does not feature small seconds, nor does it feature an hour totalizer on the chronograph. However, the column wheel mechanism provides very smooth action on the pushers and makes the starting and stopping of the chronograph smooth and not jumpy like you would see on a cam actuated chronograph which uses a different type of mechanism.

The escapement (escape wheel and pallet fork) is made from silicon
