Seiko Luxe Prospex Seiko Diver's 60th Anniversary Limited Edition SPB509

1968 Heritage Diver’s GMT Seiko Diver’s 60th Anniversary Limited Edition. Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Driven by rich legacy that has set the standard for dive watch specifications and a heritage of iconic design, Prospex continues to keep going forward with precision timekeeping, crafted for the modern world. This extraordinary Limited Edition, available only in a controlled production run of 6,000, with the serial number engraved on each caseback, reimagines Seiko’s landmark 1968 diver’s watch and celebrates the 60th anniversary of the beginning of Seiko’s dive watch story. Framed by a Made-in-Japan navy-blue ceramic uni-directional rotating elapsed timing bezel with knurled edge for enhanced operability, the rich blue wave patterned dial draws inspiration from the “wave” mark, created in 1962 as a symbol of high-grade water-resistant timepieces and displayed on the casebacks of Seiko’s divers to this day. Providing an upgraded power reserve of approximately 72 hours, the 24-jewel automatic GMT movement beats at a frequency of 21,600 vibrations per hour and offers manual winding capability. The exceptional Limited Edition is updated with a 300 meter water resistance and features a date calendar, gold-tone GMT hand, and large LumiBrite markers and hands for enhanced legibility. The GMT hand can be set independently in one-hour increments, without interrupting the time-of-day hands, to provide a second time zone reading at a glance. Crafted of stainless steel with super-hard coating, this superbly functional timepiece includes an anti-reflective sapphire crystal, screwdown crown and caseback, as well as a specially developed slide adjuster clasp allowing for easy size adjustment.
