Inspired by the black sand beaches of Hawaii

This rugged new dive watch draws inspiration from the Kaimu beach in Hawaii, a world-renowned dramatic, volcanic black sand beach in the Puna district. Based on the Big Island, Kaimu is a very young black sand beach with a rich history as it was devastated by an eruption from the nearby Kilauea volcano in 1990. Kaimu is an incredible example of endurance as the beach and local habitat have replenished, supported by locals and visitors planting sprouted coconuts in order to revitalise the local habitat and replaced the lost vegetation, restoring the area to its former beauty.

The trademark of the Supermarine collection is that it highlights the connection between sea and air, a range that has been designed for the water but very much inspired by aviation principles. Turning the watch over reveals a closed case back with a new engraved wave pattern. This reference also incorporates a uni-directional ceramic rotating bezel and is manufactured using Bremont’s Trip-Tick® three-piece case construction, housing a beautifully finished and chronometer-tested movement.
