Technical data

The best Zirkel ever! Okay, to be honest, it's the first upgrade for our beloved model. Anyways, it deserves this title more than ever. And again, the improvements are based on your feedback as the watch is the product of the community philosophy Sternglas is built upon. The renowned movement Caliber 9015 from the traditional japanese manufacturer Miyota does not only improve the technical accuracy of the watch, but also enables us to reduce the thickness of the case with its conical character by 17%. Additionally, we have tidied up the dial a little bit. The Automatik-writing as well as the date field are now centered at the 6-a´clock position to underline the overall symmetric expression of the watch.

Sophisticated, unobstrutive. The new Zirkel.
