Part of the iconic Prospex ‘Black Series’, the SSC923P1 'Night Vision' Speedtimer is inspired by underwater night diving, reflecting the clarity of a night scope. The grey dial features high-intensity green Lumibrite Pro on hands and indices, providing enhanced visibility in low light. This special Lumibrite is the first of its kind in Seiko’s lineup, delivering a brighter and longer-lasting glow for optimal readability in darkness.

Built for durability, this watch is encased in scratch-resistant sapphire glass, with a ceramic bezel that maintains its finish even in challenging conditions. A practical day-date display sits at the 4:30 position, and the watch is paired with a resilient black nylon strap for a bold look and comfortable fit.

The solar-powered V192 calibre movement powers this chronograph with an accuracy of +/- 15 seconds per month, allowing for precise measurement of elapsed time in the classic Speedtimer style. Seiko Prospex watches, designed for professional specifications, are made for adventurers and sports enthusiasts who need reliability in extreme environments.
