The Doxa SUB 300T has a tonneau-shaped stainless steel case modelled after the original 1969 SUB 300T Conquistador -one of the first commercially available watches with helium release valve-, updated with technical refinements such as waterproofing up to 120 bars. Power comes from a self-winding movement with date in the form of caliber 2824-2. Reference 840.10.361.31 has a Yellow dial.
