Bremont gives its ceramic Supermarine diver a deep-blue finish.

Bremont has added the Supermarine Full Ceramic Deep Blue to its dive-watch line. The limited edition uses a 43 mm blue ceramic case and bezel insert around a black wave-pattern dial, with a titanium inner case and caseback helping reinforce the structure.

The watch is rated to 500 meters and includes a helium escape valve. Its BB64AH automatic movement, based on the Sellita SW300-1, runs at 4 Hz and offers a stated 56-hour power reserve; buyers can choose leather, rubber or textile straps.
