PROSPEX AUTOMATIC GMT LIMITED EDITION SPB411

Land Mechanical GMT Limited Edition. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate a long history of sports watch excellence with re-creations and re-interpretations of landmark achievements. Based on the 1968 Navigator Timer, the first Seiko mechanical GMT watch with a rotating bezel, this extraordinary Limited Edition is available only in a controlled-production run of 4,000, with the production serial number engraved on each caseback. With the trim, sophisticated lines of the original, including a smaller 38.5mm case, comfortable five-row bracelet and classic box-shaped sapphire crystal with the addition of anti-reflective coating on the inner surface, this rugged, yet elegant watch also features a gray radial sunray dial with a vintage Seiko logo, while the screwdown caseback offers the original layout. The red GMT hand, as well the one-hour increment markings on the bi-directional rotating bezel, permit easy 24-hour reading. With an exceptional power reserve of 72 hours, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour and offers manual winding capability. Crafted of stainless steel with super-hard coating, this superb timepiece also includes a date calendar and a tri-fold push button release clasp. Packaged in a Limited Edition collectors’ box. 10 bar, 100M Water Resistant
