Bradner Automatic Iris Depth

The Spinnaker Bradner Collection is a modern reimagining of the classic compressor-style diver, defined by its internal rotating bezel and dual-crown architecture. This design allows for a sleek, integrated silhouette that protects the timing bezel beneath a scratch-resistant sapphire lens, eliminating the external bulk of traditional dive watches. It serves as a high-performance tool that balances mid-century maritime aesthetics with technical reliability for both aquatic and daily use.

Housed in a 42mm marine-grade stainless steel case with a 15mm thickness, the Bradner delivers a rugged and confident presence on the wrist. The multi-dimensional 3D-moulded gradient dial features high-contrast markers and Swiss Super-LumiNova for exceptional legibility in all lighting conditions. Engineered with 180-meter water resistance and a secure dual-crown system, this timepiece is built to withstand professional underwater environments while maintaining a refined profile.

At its core is the reliable Miyota 8215 automatic movement, chosen for its self-winding capability and long-term mechanical durability. This caliber powers a smooth sweeping seconds hand and includes a date complication, all visible through an exhibition caseback. Backed by a 2-year international warranty, the Bradner remains a definitive choice for those seeking a unique, compressor-inspired timepiece with contemporary performance.
