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 silver-white 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.
