Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to
celebrate a long history of sports watch excellence with recreations & reinterpretations
of landmark achievements.
Marking the 55th anniversary of Seiko’s first diver’s watch by recreating 1968’s Hi-Beat,
one-piece case, saturation diver, this extraordinary timepiece is available only in a limited
edition of 1,100, with the serial number engraved on each case-back.
Upgraded with a dual-curved anti-reflective sapphire crystal, it is crafted of Seiko’s new
Ever-Brilliant Steel, offering an exceptional level of corrosion resistance and a lighter,
brighter finish.
The rich blue- gray dial, designed to suggest the ocean depths at the point at which
blue yields to darkness, features a date calendar and LumiBrite hands & markers.
Following ISO standards for diving to depths of up to 300 meters, this saturation diver
includes a black one-way rotating elapsed timing bezel, screw-down crown, and secure
silicone strap, also in oceanic blue-gray.
The proprietary hi-beat, 37-jewel, caliber 8L55 automatic movement, assembled
expressly for diver’s watches at the Shizukuishi WatchStudio, beats at a frequency
of 36,000 vibrations per hour, with a power reserve of approximately 55 hours, and
can be wound manually or automatically.
