This model is no longer available in our current range.

The limited edition of 150 pieces chronograph 901 is ample proof of our expertise in the field of case-making. We have collaborated closely with SUG in Glashütte, which produces the technologically sophisticated cases for our company. What is special about this case is the ability to finely adjust the lugs, allowing users to extend or shorten the bracelet length. The mechanism is built into the case and permits the bracelet to be altered by up to 3 x 0.8 mm per lug side. This increases wearing comfort, as the bracelet length can then be adjusted flexibly as the occasion requires. From an engineering viewpoint, the solution involves a complex case design. This presented SUG with an unusual challenge in terms of design and production.

The polished and satinized stainless steel case is surface-hardened with TEGIMENT Technology, making it especially scratch-resistant. Temperature Resistance Technology ensures that the watch functions correctly within a temperature range of – 40 °C to + 80 °C.
