The Orient RA-AA0E01S is an awesome diving watch with an in-house Orient Cal. F6922 automatic (mechanical) movement. The model is inspired by the 1969 Orient original and has embraced all the vintage queues, including an original world map. 

The watch has an internal bezel that allows for a simplified 24 hour display, which is operated by the second crown, but also 200m water resistance and a day indicator at 3. It will look great with a suit or casual wear, so it's a true all-rounder with a great design pedigree, great quality and a true mechanical in-house movement.
