Buben& Zorweg One Perpetual Calendar Deluxe

In 2012, BUBEN&ZORWEG introduced an exclusive wristwatch ONE, equipped with a perpetual calendar. The classic ONE Perpetual Calendar complication can be distinguished by its design with clear classic lines and the perfectly integrated complication. Now this timepiece will be adorned with the pure beauty of precious diamonds from Germany’s best gemstone setters.

The MHO calibre by master watch maker Martin Braun was modified exclusively for BUBEN&ZORWEG to create the BZ01 – an innovative highlight of modern watch movement technology. The scope of delivery naturally includes the BUBEN& ZORWEG HANDWOUND – yet another piece of inspired technology and the perfect complement to the ONE.
