The Seiko Prospex SPB451 elevates the beloved 62MAS reinterpretation with meaningful technical upgrades that matter to serious enthusiasts.
Where previous generations offered 200 meters of water resistance, this latest iteration achieves ISO-certified 300-meter capability, a significant enhancement for a watch measuring just 40mm in diameter and 13mm thin. The sunray-finished blue dial captures light beautifully, its color shifting from deep navy to near-black depending on viewing angle.
Powered by the new Caliber 6R55, this timepiece delivers an impressive 72-hour power reserve, providing three full days of autonomous operation between wearings.
The movement beats at 21,600 vibrations per hour through its 24-jewel construction, offering both automatic winding and manual wind capability. Seiko relocated the date window to 4:30, allowing a full-size luminous marker at 3 o'clock for improved symmetry and enhanced ISO compliance. The redesigned bracelet features shorter pitch links and a refined clasp that better match the sophisticated case architecture, with super-hard coating protecting the stainless steel from daily wear. The curved sapphire crystal, treated with anti-reflective coating on its inner surface, ensures excellent legibility across varied lighting conditions.
