The Executive Worldtime Power Reserve is one of Orient's most unique and appealing timepieces. It features a mechanical self-winding movement with a dual internal bezel worldtime indication, including a day/night function, and a convenient power reserve indicator. The stainless steel case (43 mm x 12.8 mm), features brushed and polished accents. The dial has a small seconds display at 6 o'clock, a date wheel at 9 o'clock and a power reserve indicator at 12 o'clock. The dial is black and white, with three different guilloche patterned designs. A crown at 2 o'clock adjusts the outer most internal worldtime city display (bidirectional internal bezel). The lower crown, at 4 o'clock, adjusts the time, date and inner most worldtime hour display (bidirectional internal bezel). These bezels allow you to simultaneously view times around the world, including if it is day or night.
