CronotempVs 6 by by Habring²
A version of the Habring² “Springende Secunde” manual wind variant with power reserve indication and low-torque warning at six o’clock.
Differences between this and the standard model are a modified dial with a window for the power-reserve indication, a winding/low torque warning and a longer seconds hand.
The larger 3/4 bridge on the back covering most of the movement.
