Here is the latest model in the Orient 3-Star automatic series. The 3-Star automatic is an entry level model and due to the large number of models and variants, you are unlikely to see the full catalog on the Internet. Traditionally, they range from 34mm to 38mm in diameter (except for the vintage Crystal models). The latest models however are much larger. This particular model measures 43mm across excluding crown.
Here is a quick photo review.
