Erwin

Habring²’s flagship dead-beat-seconds watch: the A11MS caliber drives a one-tick-per-second sweep through a Habring-designed mechanism patented in 2012. Made by Maria and Richard Habring in Sulz im Wienerwald, Austria; the watch the trade points to when it explains why dead-beat seconds is a complication worth knowing.

Which ref to buy

Richard and Maria Habring founded Habring² in Austria after Richard's tenure at IWC. The Erwin is their fundamental three-hand watch: a simple time-only piece with an in-house caliber that prioritizes repairability by independent watchmakers over proprietary design. Named for Erwin Sattler.

Habring² Erwin · ErwinBuy
Erwin: time-only Austrian independent, in-house Habring A06 caliber, designed for independent watchmaker repairability, limited production.
The case for it:
The Erwin is built on a philosophical premise that most watches abandon: it should be repairable by any competent watchmaker, not just the brand. The A06 caliber documents this intention in its architecture. For collectors who care about long-term serviceability as a feature, Habring² is the most honest choice in the independent segment.
Consider instead if:
Habring² secondary market is limited to Austria and a small number of specialist dealers globally. Brand recognition is minimal outside horology circles. Buy it because the philosophy resonates, not for any other reason.
