Details:
Presage Classic Series. Offering the finest in Japanese mechanical watchmaking, the Presage Collection blends precision technology with superior craftsmanship and design. The Presage Classic Series draws from the colors, materials and textures of traditional crafts, each timepiece gracefully expressing Japan’s timeless beauty. In ‘ai-iro,’ an indigo tone thought to be a “lucky color” during the time of samurai warriors, the curved dial of this streamlined design has a dramatic gradation and a richly textured pattern evoking lustrous silk fabric, capturing and reflecting ambient light to create a heightened sense of depth and beauty. Visible through both the open aperture dial and see-through caseback, Seiko’s 6R caliber, 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour, with an exceptional power reserve of 72 hours, manual winding capability and a 24-hour complication. Crafted of stainless steel, the case is constructed with smooth curved surfaces and includes a dual curved sapphire crystal, echoing the contours of the dome-shaped dial. The retro-inspired multi-row bracelet with curved top surfaces helps achieve a superbly sleek and comfortable fit and is equipped with a deployment clasp with push button release. 10 bar, 100M Water Resistant
