Prospex Seiko Watchmaking 110th Anniversary Save the Ocean Limited Edition GMT. To mark 110 years of watchmaking excellence, Seiko is highlighting its continuous dedication to evolving technology, as well as diversity, equality and the sustainable manufacturing necessary to meet environmental challenges. Based on Seiko’s iconic 1968 diver’s watch, this landmark automatic GMT watch, available only in a controlled-production run of 4,000, with the serial number engraved on each caseback, also extends the Prospex tradition of celebrating its rich legacy of innovation in high-intensity timekeeping by re-creating and re-interpreting signature achievements. This extraordinary Limited Edition features Seiko’s first mechanical GMT movement in a diver’s watch, caliber 6R54. Providing a power reserve of approximately 72 hours, the longest of any Seiko mechanical watch, this 24-jewel automatic GMT movement beats at a frequency of 21,600 vibrations per hour and offers manual winding capability. The blue 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. Expressing the power of nature, the three-dimensional pressed pattern ice-blue dial suggests the majesty of polar glaciers, the extreme world in which Seiko diver’s watches proved their excellence, now imperiled by climate change. Framed by a Made-in-Japan blue-gray ceramic uni-directional rotating elapsed timing bezel with knurled edge for enhanced operability, the dial also features LumiBrite hands and markers, and a date calendar. Following ISO standards for scuba diving to depths of up to 200 meters, this exceptional timepiece is crafted of stainless steel with durable super-hard coating, screwdown crown and caseback, anti-reflective sapphire crystal, new three-link slim profile bracelet, and a tri-fold push-button release clasp with secure lock and extender. This environmentally conscious design emphasizes Seiko’s commitment to conservation by offering an additional fabric strap made of 100% recycled plastic bottles, woven with the traditional Japanese Seichu braiding technique in a gradated gray suggesting glacial ice. As part of Seiko’s “Save the Ocean” campaign, a portion of the proceeds from sales of this extraordinary Limited Edition will be contributed to marine conservation. Packaged in a Limited Edition collectors’ box. 200m Water Resistant.
