Seiko Prospex Black Series Special Edition Automatic SRPK43

Navigating the depths of the ocean can pose challenges, especially when light is scarce. Seiko's Prospex SRPK43 Night Vision watch enhances its robust 200m water resistance with exceptional readability in low-light conditions. This is achieved through the use of Green Lumibrite Pro, illuminating the hour and minute hands as well as the indexes on the black dial, lending the watch a night vision-like appearance that inspired its name. Additionally, the dial features a day/date display at 3 o'clock, driven by a 4R36 automatic mechanical movement. To complete its stealthy aesthetic, the stainless steel case and matching bracelet are coated in black.
