The Zeitwinkel caliber ZW 0102 is a mechanical manufacture movement with automatic winding. Developed by Zeitwinkel especially for watches from the first series, it is manufactured in small-quantity lots in Jura (Switzerland) with high precision machinery and meticulous diligence.
A robust, accurate and versatile basic movement that can be equipped either with a sweep or a small second and has a relatively large date display as an option. The running time is 72 hours.
The movement has the formidable diameter of 30.4 mm, 30 jewels and a total of 257 components, a frequency of 28,800 oscillations, a Glucydur balance and a robust three-quarter plate that plays a significant role in the mechanical stability of the movement. All plates and bridges are made of German silver. This material is noticeably harder than the brass that is usually used and requires the greatest precision in its manufacture and ornamentation.
Our caliber ZW 0102 is chamfered and hand-decorated. After thorough quality inspection and five-stage calibration, it is installed in the housing by our watchmakers and subjected to a running test that lasts several days. Only when the measured accuracy lies within our strict tolerance range is the caliber ZW 0102 sent on its journey to a new owner together with its Zeitwinkel watch.
