Citizen-Eco-Drive-Promaster Professional Diver-BN0166-01L

  • Inspired by the beautiful oceans that unite the world, the watches of Citizen's UNITE with BLUE series join the colors of the seven seas on one 100% recycled polycarbonate dial.

    This example, which comes as part of the dive-ready Promaster collection, marks a unique take on the classic sports style. The robust silver-tone stainless steel exterior ensures up to 200 meters of water resistance, making use of a 4 o'clock screw-down crown placement and an easy-grip bezel executed in a two-tone design is reminiscent of a sparkling emerald green ocean.

    The strap made from biomass-based polyurethane, which includes plant-based materials, secures the timepiece to the wrist. The highly-legible dial is brought to life through pigment-free ink that uses light – the same light that powers the Eco-Drive technology within – to reflect off the surface of the ink microstructures and create an array of aquatic shades.

    This style is part of the UNITE with BLUE collection, which highlights Citizen’s commitment to sustainability including a Promaster Dive model and CITIZEN L Bianca style. Sustainably powered by the brand’s proprietary Eco-Drive technology, both timepieces feature a structural color dial, inspired by the oceans that unite the world
