2007 Model / SWATCH / Irony Chrono / YCS490G / Mar Azulo This is a valuable vintage SWATCH, the popular Mar Azulo model. I've tested it with a new battery, and both the watch functions and the chronograph function are working. Operation confirmed. Time adjustment is possible by turning the crown. The body and band are still in good condition! Comes with the original box. No returns or exchanges. In accordance with Mercari's policy, I will ship it without a battery. Thank you. Operation: Good
