SEIKO SELECTION SBTR027 — Blue-Gray Quartz Chronograph
The SEIKO SELECTION SBTR027 combines a blue-gray dial with a stainless steel case and silver-tone bracelet. Also listed by retailers under the Spirit name, this Japanese domestic market model features a sporty three-subdial layout, a black tachymeter bezel and the battery-powered Caliber 8T63 quartz movement.
Blue-Gray Dial and Sporty Chronograph Styling
The blue-gray dial gives the SBTR027 a distinctive yet understated appearance, complemented by silver-tone hands and hour markers. Three subdials provide chronograph minutes, a 24-hour indication and running seconds, while a date window adds everyday practicality. The black tachymeter bezel reinforces the watch's sports-inspired design.
Caliber 8T63 Quartz Chronograph
Seiko's Caliber 8T63 provides dependable battery-powered timekeeping with an average accuracy of ±15 seconds per month. The stopwatch measures elapsed time in 1/5-second increments for up to 60 minutes. A separate 24-hour subdial follows the main time display and is not an independently adjustable second time zone.
The specified battery life is approximately three years. Actual battery life depends on usage, and the battery fitted at purchase may have a shorter remaining life.
Stainless Steel Construction and Hardlex Crystal
The round stainless steel case measures 47.0 × 39.8 × 11.7 mm and is paired with a stainless steel bracelet. A Hardlex crystal protects the dial, while LumiBrite on the hands and indexes helps with visibility in low light after exposure to light. The bracelet closes with a three-fold clasp featuring push-button release.
A screw case back and 10 bar water resistance complete the watch's practical everyday specification.
