The square case of Bell & Ross’s watches, with its distinctive four corner screws, is instantly recognisable. As the name suggests, the Diver Blue is a true deepsea explorer, rated to depths of 30 bar. To maximise readability underwater, it has Superluminovacoated markers and a yellow hour hand. The hour hand becomes less visible at depths, while the minute hand remains bright – all- important when timing a dive. Like all good dive watches, it comes with a unidirectional bezel.
