A Classic and Elegant 3-Day Automatic Watch
This watch adopts the classic style of models with mechanical Caliber 9S67 movements, preserving the design in every way while excluding the power reserve indicator and packing a Caliber 9S65 movement, instead.
The watch boasts a maximum 3-day power reserve and combines the latest in hairspring technology with an escapement (escape wheel and pallet) developed through Seiko's MEMS technology to achieve high accuracy and stability when worn.
The design embodies a pure classical elegance with box-shaped sapphire crystal glass, Zaratsu polished lugs, a brown leather band, and a blue steel hand complementing an ivory dial.
While attention-grabbing in its own right, the watch also brings out the individuality and maturity of wearers of all ages with an affinity that only increases throughout the years.
Case : Stainless steel Case back: Stainless steel and sapphire crystal Glass : Box-shaped sapphire crystal Coating : Anti-reflection coating on inner surface Lumi Brite : - Case size : Diameter 39.5mm×Thickness 13.1mm
Movement : Caliber 9S65 Driving system : Automatic with manual winding mechanism Power reserve : Approximately 72 hours Accuracy : +5 to -3 seconds per day (under a static use) ; This accuracy is the result of measuring the loss/gain of the time for seventeen days before the inside movements of the watch are put in the case. The measurement has been done in the factory where temperatures or position of the movements are controlled. When the watch is actually worn, the accuracy should be from -1 second/day to +10 seconds/day (-1 second/day to +8 seconds/day for Cal.9S85, 9S86).
Clasp : Three-fold clasp with push button release Water resistance : 3 bar Magnetic resistance : 4800 A/m (60 gauss) Weight : 84.0 g Remarks : ・See-through back
