Built for the technically adventurous, it stands out for its robustness and bold design. A transparent, screw-down case back ensures impressive water resistance up to 20 ATM, so you can face the elements with complete confidence.

The Dial

The dial of the Seiko Prospex Alpinist exudes timeless appeal with its blue, sunray-brushed finish that catches the light beautifully, bringing a dynamic shimmer to your wrist. Bold, legible Arabic numerals stand out crisply against the blue background for quick, effortless reading. The hands and hour markers are coated with a luminescent material, ensuring clear visibility even in low-light conditions. A discreet date window at 3 o'clock keeps you on schedule. An integrated compass on the dial underscores the model's practicality, enhancing its usefulness on outdoor adventures. The sapphire crystal, renowned for its scratch resistance and anti-reflective coating, protects the dial while eliminating distracting glare for a perfect read at all times.

The Movement

At the heart of this watch beats the Seiko 6R55 automatic movement, a hallmark of Japanese precision. This self-winding caliber, with its visible rotor through the transparent case back, delivers an impressive 72-hour power reserve - perfect for those who prefer not to think about winding their watch. Engineered and manufactured by Seiko Corp., this sophisticated mechanism showcases exceptional horological craftsmanship, honoring tradition while meeting modern demands for autonomy and performance. The watch displays hours, minutes, and seconds, along with a date indication.

The Bracelet

The watch's elegance is elevated by a stainless steel bracelet in grey with a polished finish that pairs seamlessly with the case. A 20 mm lug width ensures a secure, all-day comfortable fit. The single-fold deployment clasp makes fastening effortless while keeping the watch firmly on the wrist. This choice of material and design guarantees not only the bracelet's durability but also its resistance to everyday wear.

Water Resistance

With water resistance up to 20 ATM, this watch is the ideal companion for diving enthusiasts and anyone involved in prolonged water activities. This level of water resistance means it can withstand not just splashes but full immersion, making it safe for intense water sports such as swimming, jet skiing, and even scuba diving. The robust construction - backed by stainless steel and a screw-down case back - makes this a watch built for lasting durability and performance in aquatic environments.
