Contemporary, surprising, unique. resolutely stylish and racy. True to its brand motto "One Watch, 4 faces", the BYRNE GYRO DIAL 311 is a living, evolving watch. Every evening at midnight or noon, the watch's 4 indexes change instantly and perfectly, and a new design takes shape. Roman numerals meet Arabic numerals, and if you're going for sobriety, choose the ghost numerals. The fourth face features the secret number (a choice of one of the 4 indexes from 0 to 9) which will be engraved on the winder. The hyper-profiled grade 5 titanium case reveals its power in a satin polish. The black dial, with its changing colors, undulates from slate gray to intense black. The blue dial varies from blue to navy blue. Demanding, totally Swiss-engineered. The hyper-tested 5555 caliber gave birth to the Gyro Dial and the first classic BYRNE Watch series, the 311.
