From the Promaster Dive Collection. The past becomes the present with the new Promaster dive automatic watch by Citizen. Going deeper into the history of the original version of this diving watch, it was released in 1989 for the new generation of dive watch enthusiasts. Featuring a three-piece, 44mm case, sapphire crystal, and a black polyurethane strap, the black rotating bezel with a black easy grip aluminum ring surrounds the green dial and luminous hands and markers. This technically advanced and automatic sports watch comes in an exclusive collector’s dive tank box and is ISO-compliant with a screw-down crown and water resistant to 200 metres.
