Here we have a Seiko chronograph that was envisioned to be used for car racing, and inspired by the view of an engine compartment. The blue dial is multi-layer, with embossing and metallic applied elements. These features add depth to the dial. Go ahead, zoom in and check out the details. It's not only good looking. This Seiko Quartz Chronograph is also very functional! A tachymeter is shown on the outer portion of the dial and that can be used to measure units per hour. The 8T63 movement has a stopwatch that tells elapsed time to the nearest 0.2 seconds, and allows for events up to 60 minutes. The hands and the 12 hour marker are filled with white luminous material for reading the time in the dark. The 41mm diameter brushed stainless steel case is 12.5mm thick and 48mm tip to tip. With the bracelet the weight is 85 grams. The nylon strap uses grey and blue lines to perfectly match the dial. The movement is a Seiko Caliber 8T63 that is powered by a battery. Water resistance is 10 BAR or 100 meters
