The Astron Big-Date watch has a classic design with a large date window at twelve o'clock. At the six o'clock position you will find a dual time dial displaying a second time zone. View the time in your home zone at the touch of a button. The design is refined, with slim hands, 3D indexes, and on some models Roman numerals.
The Seiko polishing technique developed especially for the Astron creates a high contrast between matt and glossy surfaces. This superior finish emphasizes the luxurious character of this Big Date watch.
