The Seiko Prospex watch stands out with its bold yet refined aesthetic. Its stainless steel case measures 42 mm in diameter and 13.30 mm in thickness, striking the perfect balance between sophistication and functionality. The brushed and polished steel finish gives it a modern, durable look. Its ceramic bezel - both decorative and functional - is rotating for practical use. Paired with a screw-down case back, it ensures strong resistance against the elements.
The dial on this watch makes a statement with its striking green tone. Protected by an anti-reflective sapphire crystal, it delivers outstanding legibility and lasting durability. The hands and indices are coated with LumiBrite, ensuring optimal visibility even in low-light conditions. The analog display is enhanced by a minute track for precise time reading. A discreet date window blends seamlessly into the design, while the GMT function adds a second time zone.
At the heart of this watch, the Seiko 6R54 automatic movement delivers exceptional accuracy. Crafted in Japan, it operates at a frequency of 21,600 vibrations per hour. The 72-hour power reserve keeps this model running even after several days off the wrist. With features like GMT, this movement is the perfect fusion of watchmaking tradition and technical innovation.
The bracelet on this watch completes its masculine, refined look. Crafted in stainless steel, it features a blend of brushed and polished finishes. Its 20 mm lug width adds structural integrity while adapting effortlessly to different wrist sizes thanks to a secure folding clasp built for an active lifestyle.
This watch is water resistant to 30 ATM, equivalent to 300 meters of depth. Built for swimming and diving, it withstands pressure and water ingress thanks to carefully integrated components including the screw-down case back and screw-down crown.
