DELIVERED WITH AN ADDITIONAL HEAVY DUTY BLACK SYNTHETIC CANVAS STRAP. Symbolizing the sea, blue was chosen as the color of this new version of the BR03-92 Diver. Beyond its blue dial, rubber strap and aluminium insert on the bezel, this BR03-92 Diver Blue aims to achieve maximum readability with indices coated in white Super-LumiNova® and a yellow hour hand. Underwater, the colours vanish one after the other due to the loss of light intensity. The yellow hour hand will therefore fade away to give precedence to the minute hand, which must be visible to ensure the diver's safety. THE TECHNICAL PARTICULARITIES OF SWISS STANDARDS Only watches that meet certain requirements defined by international standard ISO 6425 can be labelled "diving" watches. The twelve-page specification of the International Organization for Standardization (ISO) relating to diving watches contains an exhaustive list of the essential qualities of a “wristwatch designed to withstand diving in water at depths of at least 100 m and possessing a system to control the time”. The general requirements for a professional diving watch recognised as such by standard ISP 6425 are – among others – a minimum water resistance of 100 metres and the presence of a time preselection device (a 60-minute calibrated uni-directional rotating bezel) which is protected against accidental rotation or incorrect setting. This colour combination, paired with the emblematic square shape of the BR collections, lends the BR03-92 Diver Blue a sporty yet attractive aesthetic.
