Inspired by the shifting hues of the sea, the Limited Edition Promaster Dive with structural ink dial technology reflects light in vivid aquatic shades while delivering robust functionality. Sustainably powered by our Eco-Drive Caliber E168, the watch is fueled by light - any light - and never needs a battery. Bold on the wrist at 44mm, the stainless steel case is ISO-compliant and water resistant up to 200 meters, secured with a sustainable BENEBiOL? strap made with plant-based materials. Luminous hands and markers ensure legibility against the pigment-free structural ink dial, crafted from 100% recycled polycarbonate. A unidirectional bezel and functional date display at 3 o'clock add utility for everyday and underwater use. This special edition arrives in an exclusive Promaster Dive tank box. Limited to XXX unnumbered pieces worldwide.
