From Citizen's Promaster Sky Collection, this radio-controlled timepiece is the perfect watch for frequent flyers and jetsetters. This watch automatically adjusts to the correct time by capturing a time signal within four geographical regions: Europe, North America, China and Japan. The watch features Eco-Drive technology, a stainless-steel brushed case, green bezel and dial. Additional features include sapphire glass, perpetual calendar, alarm, stainless-steel double-push fold-over clasp with safety, and water resistance up to 200 meters.*Please note that the radio-controlled functionality will not work in Australia due to the absence of radio transmitting stations within range. These stations are exclusive to four regions: Europe, USA, China and Japan. However, this does not affect manual time adjustment. Please refer to your instruction manual for guidance.
