Product Description
First introduced in 1969, the Speedtimer was a major innovation milestone in Seiko’s watchmaking heritage.
This latest design is the first Speedtimer to feature the robust and reliable 6R in house automatic calibre and the slimmest ever 6R model in the brand’s history, at just 11.95mm depth.
With its super-hard coating, the flowing case shape of this model was first used in 1972 on the famous Seiko ‘Panda.’ Under the curved sapphire glass, a black dial is encircled by a countdown timer function. The strong Lumibrite coating on the inner-ring reference triangle allows for the countdown timer to be used with clarity during both day and night. Compact and comfortable, this Speedtimer has a diameter of 39.5mm, and a water resistance of 200m.
The in-house 6R55 automatic calibre is accurate to -15/+25 seconds per day, with a three day power reserve.
Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
