A version of the Habring² “Springende Secunde” manual wind variant with power reserve indication and low-torque warning at six o’clock.
The larger 3/4 bridge on the back covering most of the movement.
The view of the Dead-Beat Seconds mechanism at work.
Visible beneath a sapphire crystal caseback, the movement powering the L.U.C Perpetual Twin, mechanical automatic calibre L.U.C 96.22-L, is a work of true technical and artisanal mastery.
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.
Despite what many might think, this complication was invented over a century before the quartz watch.
As with all watches from Habring², the box is simple and functional. Delivered with basic replacement parts in case it needs service.
