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. Watch straps made from #tide ocean material® not only look great and are very robust, they also serve a good cause: The high-quality yarn that makes up this textile strap started its life as plastic waste fished from the oceans.
