SEIKO Men’s Blue Dial Silver Stainless Steel Band Prospex

Product Overview

The SEIKO Men’s Blue Dial Silver Stainless Steel Band Prospex Sea Automatic Analog Watch is a precision-engineered timepiece built for men who value performance, durability, and refined style in equal measure. As part of SEIKO’s respected Prospex collection—renowned for its professional-grade sport watches—this model delivers reliable functionality in demanding environments, from deep-sea diving to daily urban wear. Powered by a self-winding automatic movement, it eliminates the need for batteries by converting the natural motion of your wrist into energy to keep accurate time. The striking gradated blue dial transitions smoothly from deep ocean hues to lighter tones near the center, creating a dynamic visual effect that captures the essence of underwater exploration. Paired with a matching stainless steel case and bracelet, the watch offers a balanced, substantial feel on the wrist while maintaining versatility across casual, business, and adventurous settings. Certified to meet ISO 6425 standards for dive watches, it ensures dependable operation under pressure and in challenging conditions, making it a trustworthy companion for both recreational and professional use.

Key Features

• Automatic Movement: The in-house 4R36 caliber movement is self-winding, harnessing kinetic energy from your daily movements to maintain consistent timekeeping. It also allows for manual winding, ensuring the watch stays powered even during periods of inactivity.
• 200-Meter Water Resistance: Designed to perform at depths up to 200 meters, this watch is suitable for scuba diving, snorkeling, swimming, and other water-based activities. Its sealed construction protects internal components from water intrusion under pressure.
• Hardlex Crystal: The dial is shielded by Hardlex mineral crystal, a proprietary SEIKO material known for its excellent scratch resistance and clarity. It maintains visibility in bright sunlight and resists everyday wear and tear.
• LumiBrite Markers: Hour markers and hands are coated with SEIKO’s LumiBrite luminescent material, which charges quickly under any light source and provides long-lasting, bright visibility in darkness—ideal for night dives or low-light environments.
• Stainless Steel Case and Bracelet: Both the 42.5mm case and the three-link bracelet are crafted from high-quality stainless steel, offering resistance to corrosion, especially in saltwater and humid climates. The polished and brushed finishes enhance durability while adding a sophisticated look.
• Day/Date Display: A practical day and date window at the 3 o’clock position provides at-a-glance information, enhancing everyday usability without compromising the clean dial design.
• Unidirectional Rotating Bezel: The 120-click bezel rotates only counterclockwise, a critical safety feature for divers to prevent accidental overestimation of dive time. Its ridged texture ensures a secure grip, even when wearing gloves.

Important Notes

The watch arrives in original SEIKO packaging, measuring 5.12 x 3.7 x 3.46 inches and weighing approximately 11.99 ounces. It is part of the Prospex collection, SEIKO’s line of sport watches developed for extreme conditions. For specific warranty coverage, customers should consult the manufacturer’s official documentation. The product is designed for adult male wearers and ranks among popular men’s wristwatches in its category. To maintain optimal performance, SEIKO recommends professional servicing every three to five years. While the watch is water-resistant to 200 meters, users should ensure the crown is fully screwed down before submersion and avoid operating buttons or the crown underwater to preserve integrity.
