Presage Sharp-Edged Series GMT Zero Halliburton Limited Edition. Offering the finest in Japanese mechanical watchmaking, the Presage Collection blends precision technology with superior craftsmanship and design. The cool angularity of the Sharp-Edged Series, celebrating the fresh look of contemporary Japanese design, provides a perfect match for its first collaborative collection, a Limited Edition group designed with the iconic Zero Halliburton luggage brand. With clean functionality and graceful lines, the aluminum travel cases of Zero Halliburton, first established in 1938, have gained an enthusiastic worldwide following. Created with the blend of practicality and style characteristic of both brands, the new Limited Editions feature a distinctive dial pattern combining Zero Halliburton's double-rib design and the Presage Sharp-Edged Series' Asanoha hemp-leaf motif, a symbol of growth and prosperity dating to the Heian Period (794-1185 AD). Available only in a limited edition of 600, with the Zero Halliburton logo on each screw-down, see-through caseback, this exceptional watch is crafted of stainless steel, with black hard coating. Seiko's new, 29-jewel automatic caliber 6R64 movement, complete with GMT complication, beats at a frequency of 28,800 vibrations per hour, with a power reserve of approximately 45 hours and manual winding capability. The black dial includes a 24-hour GMT hand, power reserve indicator, date display and LumiBrite hands and markers, and is framed by a blue and black GMT bezel. A sapphire crystal features anti-reflective coating on the inner surface, while the tri-fold push button release clasp offers secure and comfortable wear. Includes a special Limited Edition collectors' case. 10 bar, 100M Water Resistant.
