Slim Solar Powered Chronograph with Sapphire Crystal | Although multi-hand chronograph cases tend to be thick, this is a solar powered chronograph with a case kept to a thickness of 9.7 mm to provide an enhanced fit. The watch boasts a flat octagonal bezel with a hairline finish that creates a sporty yet luxurious design. Uses a scratch-resistant sapphire crystal. The combination of a case and band given a black ion plate for scratch-resistance and a red accent color creates a bold design.
