From the Manufacturer:
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 aluminum insert on the bezel, this BR03-92 Diver Blue version aims to achieve maximum legibility with indices coated in White SuperLuminova® and a yellow hour hand. Underwater, the colors 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.
This new color combination, paired with the emblematic square shape of the BR collections, gives the BR03-92 Diver Blue a sporty yet attractive aesthetic.
