Other: We know this isn't technically a perpetual calendar despite its model name - It's more of a unique day-date. The red indicator arm outlines the current day of the week and the wearer simply unscrews the top crown to rotate the bezel to the current date. The red indicator arm advances once per day at midnight while the bezel remains locked. Our favorite feature on this watch is the three-color dial, reminiscent of a roulette wheel. It is anything but ordinary and sure to be a conversation piece!
