One hundred years ago, Citizen changed the world of watchmaking forever with the launch of their first pocketwatch. Today, that legacy continues with the new limited-edition Promaster Geo Trekker. This 46MM watch features a blue chronograph dial beneath anti-reflective sapphire crystal, set within a gray stainless steel case; it also has a matching bezel, chronograph and Eco-Drive movement technology, radio control, date and power reserve indication, world time, and a water resistance of up to WR200 (20 bar or 666 feet).
