Seiko Digital Quartz Rotocall Chronograph 145th Anniversary Limited Edition HFL001

"Edo Purple" for 145 Years Inspired by Seiko's classic "Rotocall" digital watch from 1982, this new Anniversary Edition takes the distinctive eight-sided rotating switch bezel beloved by astronauts and collectors alike, and wraps it in Edo Purple for Seiko's 145th anniversary.  Powered by Seiko's very own A824 digital quartz module, this Rotocall packs a laundry list of useful features, from a 100 hour, 1/100th second chronograph, to an alarm, full auto calendar (until 2074), dual time display, internal LED illumination, and yes, that beloved rotary switch bezel that earned the watch its 'Rotocall' moniker.  As Seiko marks its 145th anniversary, the venerable Japanese maker presents a new series of limited-edition timepieces. Representing the traditions that were born in Edo and passed on to modern Tokyo, as well as the spirit of creativity that defines Japan’s largest city, Edo purple-inspired colors serve as a central design element across the commemorative models. Guided by its founding philosophy to be “Always one step ahead of the rest,” Seiko continues to take on new challenges while remaining closely connected to people’s lives through time. Each model also incorporates gold-colored accents that express Seiko’s enduring commitment to enriching lives with joy and beauty.
