De Bethune DB28 GS "YELLOW SUBMARINE"

A diver’s watch in the colors of fire with a water resistance to more than 100 metres; excellent readability including in the darkest depths thanks to ingenious lighting inside the movement and a new photoluminescent blue, a different bezel that rotates this time with the crystal to indicate dive times; a titanium case for a light feel and a rubber strap for convenience; along with a five-day power reserve.
