The Dive Master is engineered for professional saturation diving. Its monoblock high-tech ceramic case provides superior scratch resistance and hypoallergenic comfort, while the unidirectional 120-click ceramic bezel graduated in luminescent Super-LumiNova allows precise elapsed dive-time tracking even in low-visibility conditions. Maximum ceramic hardness (Vickers 1200 HV) ensures the dive timer remains readable after years of field use.

Each Calibre timepiece is assembled, adjusted, and timed individually in our Geneva atelier. Expected lead time is 4–6 weeks from order confirmation. Complimentary delivery by insured courier.
