Product Details

Over the years, Bremont’s Supermarine collection as been developed to be a full function and highly capable mechanical timepiece specifically aimed at proven performance for professional divers. For 2024, significant upgrades to the collection ensure that these exacting standards are not only met but exceeded, to deliver a deeper level of performance and value.

The Supermarine 300m and 300m Date models have been entirely redesigned and now feature a sleeker and slimmer profile case shape crafted in 904L steel to maximise robustness and comfort in unison. A symmetrical case silhouette includes both crown and bezel guards, ensuring practical operation whilst increasing durability and safety by preventing accidental adjustment or damage through shocks or knocks.

Quick release stainless steel bracelet with micro-adjustment feature.
