The balance spring in this watch is made of silicon. This innovative, high-tech material is one of the latest achievements in modern watchmaking and is extremely resistant to magnetic fields, impacts and temperature changes. This improves the rate precision of the watch in the long term. The cushion-shaped case combines a square shape and gentle curves. Timepieces of this kind were especially popular in the 1960s and 1970s, which is why modern watches featuring this design often have a retro feel.
