Framed by a countdown timer dial ring that can be utilized to measure the remaining time of a particular event, the hairline-finish black dial displays the word “Speedtimer,” honoring Seiko’s legacy of sports timing. The sporty dial is accented by an orange-tipped second hand and offers a date calendar and LumiBrite hands and markers for superior visibility in low light conditions. With an upgraded power reserve of approximately 72 hours, 3 full days, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour with manual winding capability. Crafted of stainless steel with super-hard coating, this rugged yet refined watch is 200 meter water resistant while boasting the slimmest case of any Seiko 6R model, flowing seamlessly from the case to the multi-row bracelet. Topped with a curved sapphire crystal with anti-reflective coating on the inner surface, it includes a screwdown crown and caseback, and a tri-fold push button release clasp.
