Piet Hein Eek’s starting point for the dial was the iconic ring. To achieve a high level of detail, we use a special cutting method to make the teeth.

The T-series has a crown that ensures when fully pushed back the 3ATM water resistancy. The crown holds a lot of fine details made by diamond cutting.
