PROSPEX 145TH ANNIVERSARY "SEIKO BLUE" AUTOMATIC DIVER HBB001

In the second series of commemorative limited-edition watches celebrating Seiko’s 145th anniversary, a blue accent inspired by “Seiko Blue” is used. Established in the 1960s and refined over time, Seiko Blue continues to embody the Seiko brand identity. Inspired by “Seiko Blue,” a signature color established in the 1960s and perfected over the decades, blue is adopted as an accent color for the bezel and seconds hand. The combination of the two-tone bezel and a silver white dial creates a fresh and sophisticated impression on the wrist. This model inherits a case design composed of straight, blade-like surfaces, while achieving a sharper and more compact form. With chamfering on the center links, the high-quality, solid bracelet delivers a refined finish that complements the case’s linear design. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and winning design. Inspired by Seiko’s most iconic diving styles, the case retains the straight contour of the original design with a sharpness enhanced by a sleeker more compact profile. For reliable timing in rough waters, the 23-jewel automatic movement beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 41 hours, and can be wound manually or automatically. Crafted of stainless steel, this high-intensity timepiece follows ISO standards for scuba diving and is equipped with a secure screwdown crown and caseback and a tri-fold push button release clasp with secure lock and extender. 200m Water Resistant Technology Model: HBB001 Collection: Prospex Sub Collection: Automatic Diver Gender: Men Dial Color: Silver Strap Material: Stainless Steel Strap Detail: Stainless steel bracelet Lug Width (mm): 20 Movement: Automatic Caliber: 4R35 Movement Detail: Caliber 4R35 21,600 vibrations per hour 23 jewels Power reserve: approximately 41 hours Case Material: Stainless steel with super-hard coating Case Diameter (mm): 41.7 Case Thickness (mm): 12.3 Case Length (mm): 49.5 Crystal Type: Hardlex crystal Water Resistance: 200 meters follows ISO standards and is suitable for scuba diving Features Blue aluminum uni-directional rotating elapsed timing bezel Clean sunray finish silver dial Automatic with manual winding capability Date calendar LumiBrite hands and markers Screwdown crown and caseback
