Seiko Prospex Speedtimer ‘Maximum Precision’ 8R Mechanical Chronograph

Built for precise timing, the Seiko Prospex Speedtimer ‘Maximum Precision’ 8R Mechanical Chronograph houses the 8R48 calibre in a 42 mm stainless steel case with a super hard coating.

The automatic chronograph records up to 30 minutes and 12 hours, while a tachymeter turns elapsed time into speed. With 34 jewels, a 45-hour power reserve and accuracy of +25 to -15 seconds per day, it can also be wound by hand. LumiBrite hands and indexes keep it legible in low light, and a dual-curved sapphire crystal with anti-reflective inner coating aids clarity. The screw case back and 10 bar water resistance make it suitable for swimming, and a three-fold clasp with push-button release secures it. It is covered by a 3-year international warranty.
