The Seiko Prospex SSC813 is a timepiece from the Prospex Speedtimer Solar Chronograph collection. This watch draws inspiration from Seiko's first precision chronographs that were developed for international sporting competitions in 1964. The watch has a modern design and is powered by light energy, eliminating the need for battery replacements.

The chronograph function of the SSC813 can measure up to 60 minutes of elapsed time with split time measurement capability in 1/5-second increments. The watch has a white dial with a sand-blasted texture and black subdials. There is also a date calendar and a 24-hour subdial. The hands and markers are coated with beige LumiBrite, ensuring easy readability in low light conditions.

The Seiko Prospex SSC813 features a curved sapphire crystal with anti-reflective coating on the inner surface, which ensures a clear view of the dial. The watch also has a black tachymeter bezel and a screw-down caseback. The case diameter is 39.0mm, making it suitable for most wrist sizes. The watch is made of stainless steel and has a matching bracelet with a tri-fold push button release clasp.

This timepiece is water-resistant to 10 bar, which is equivalent to 100 meters or 330 feet. The watch runs on the Caliber V192, which has a 6-month power reserve once fully charged. The Seiko Prosper SSC813 is an excellent watch for those who appreciate a timeless design with modern features and reliable functionality.
