This new design line features the 6R caliber, combining a countdown dial with the traditional flow shape of Seiko sports watches established in the 1970s.
The 6R55 caliber is housed in a 20-atmosphere water-resistant case, delivering the functionality and reliability required for timekeeping in motorsports (e.
g., rallies) held in harsh environments and conditions.
The slim, 20-atmosphere water-resistant case combines excellent wearability with water resistance.
The countdown dial allows for convenient countdown measurements, such as remaining time or target time for completing a task.
The reference position markers on the dial are filled with Lumibrite for improved visibility in dark places.
/ Caliber: 6R55 / Power reserve: Approximately 72 hours when fully wound / Accuracy: +25 to -15 seconds per day / 24 jewels / Second hand stop function / Water resistance for everyday use (20 bar) / Calendar (date) function / Lumibrite: Yes (hands, indexes, dial ring) / Magnetic resistance: Yes / Screw back / Inner ring with countdown scale / Band adjustment C-ring system / Made in Japan.
