Description
SEIKO PROSPEX SPEEDTIMER SBDL085 White Panda Solar Chronograph
The SEIKO PROSPEX SPEEDTIMER SBDL085 is a Japanese Domestic Market solar chronograph featuring a white dial with contrasting black subdials. This high-contrast configuration is commonly known as a panda dial and gives the watch a distinctive motorsport-inspired appearance.
Powered by SEIKO's solar Caliber V192, the SBDL085 combines a compact 39.0 mm stainless-steel case with a 1/5-second chronograph, tachymeter scale, curved sapphire crystal and approximately six months of operation when fully charged.
SPEEDTIMER Heritage Design
The design draws on the character of SEIKO's historic SPEEDTIMER chronographs from the late 1960s and 1970s. Its compact case proportions, external tachymeter scale and contrasting subdials create a balanced sports-watch design with clear chronograph readability.
The white dial has a finely textured finish, while the black subdials visually separate the chronograph, running-seconds and 24-hour displays. LumiBrite on the hands and indexes supports visibility in low-light conditions.
Solar Caliber V192
The watch is powered by SEIKO Caliber V192, a solar quartz movement that converts light into electrical energy. When fully charged, it operates for approximately six months and delivers an average monthly accuracy of ±15 seconds.
The movement includes a 1/5-second stopwatch capable of measuring up to 60 minutes, a 24-hour hand, small seconds, a power-reserve indicator, date display and overcharge-prevention function.
Chronograph and Tachymeter Functions
The central chronograph hand measures elapsed time in 1/5-second increments. The subdial at 6 o'clock serves as the chronograph minute counter and power-reserve display, while the 24-hour display is positioned at 3 o'clock and the small-seconds display at 9 o'clock.
A tachymeter scale surrounds the dial and can be used with the chronograph to calculate average speed over a known distance.
Stainless-Steel Construction
The stainless-steel case measures 45.5 mm in length, 39.0 mm in width and 13.3 mm in thickness. A curved sapphire crystal with an anti-reflective coating on its inner surface protects the dial and helps reduce glare.
The matching stainless-steel bracelet is secured by a push-button three-fold clasp. The watch weighs approximately 161 g and accommodates a wrist circumference of up to approximately 197 mm.
Practical Everyday Performance
The SBDL085 has enhanced water resistance for daily use at 10 bar, magnetic resistance and a screw case back. Its solar movement, date display and chronograph functions provide practical performance without requiring frequent conventional battery replacement.

SBDL085 is the model number assigned to the Japanese domestic version. The corresponding international model is identified as SSC813 or SSC813P1, depending on regional notation.
