This Seiko Prospex watch embodies the perfect blend of aesthetics and functionality, aimed squarely at fans of dive watches and water sports. Its 316L stainless steel case offers exceptional corrosion resistance, ensuring lasting durability in marine environments. With a distinctive cushion shape, a 42 mm diameter, and a 13.3 mm thickness, this watch delivers both style and comfort in equal measure. Every design detail has been engineered for an optimized user experience.
The screwed caseback further ensures remarkable water resistance, making this watch as capable in extreme dive conditions as it is stylish on dry land. The overall design, while purpose-built for performance, never compromises on elegance - with a refined integration of stainless steel and a polished bezel.
The dial of this timepiece, in pure white, offers maximum legibility thanks to its luminescent hands and indices that stand out elegantly against the polished surface. The sophisticated sapphire crystal with anti-reflective treatment ensures crystal-clear vision from every angle, minimizing glare whether reading in full sunlight or underwater. The user experience is enriched by a precise analog display that shows the main time alongside a second time zone via a dedicated hand - ideal for travelers and business professionals on the go. The GMT complication further reinforces the technical and functional excellence of this exceptional dial.
At the heart of this timepiece beats the Seiko 6R54 caliber, an automatic movement renowned for its reliability and precision. This high-performance Japanese mechanism oscillates at 21,600 vph and offers a generous power reserve of 72 hours, keeping the watch running accurately even after several days without wear.
The bracelet of this watch is crafted in 316L stainless steel, perfectly matched to the case for a coordinated, sophisticated look. Its grey tone ties seamlessly into the overall design, offering a timeless and polished style. With a 20 mm lug width, it features a deployment clasp for optimal security and a comfortable fit around the wrist. Every element of the bracelet is engineered to withstand marine conditions, ensuring long-lasting wear day after day.
This Seiko watch is engineered to the highest water resistance standards, rated at 30 ATM. Built for water sports enthusiasts, it handles the pressures encountered during professional dives without missing a beat. The screwed caseback and specially designed crown provide an added layer of protection against water ingress.
