This is quite a unique watch. It is nicely decorated automatic mechanical movement with open heart with dual time displays. This watch has 3 separate movements. One center mechanical movement which operates the large sweep second hand and two smaller quartz movements that operate the two time zones. Each time zone is controlled by its own crown on either side of the polished stainless steel case. A rich looking patterned dial provides an elegant backdrop for the exposed movement. Case : Polished solid stainless steel, 45mm diameter. Band : Alligator grained leather strap. Water Resistant : 150 feet. Warranty : 1 Year.
