Reaching deep into citizen’s dive history, a 70’s classic is reimagined with a modern twist in the new promaster mechanical diver, now updated with advanced features suitable for the ocean or the office. The retro design is based on the citizen challenge diver, which was found covered in barnacles on an australian beach after being submerged in the ocean for years—but was still ticking. The lightweight and scratch-resistant super titanium™ 41mm case is complemented with a blue dial featuring embossed hands and a classic green luminous for a vintage feel. A silver-tone super titanium™ bracelet, which secures with a fold-over safety clasp, is the perfect finishing touch for this mechanical timepiece. This high-performance watch comes in an exclusive collector’s dive tank box, is iso compliant and is water resistant to 200 meters.
