The bezel action is described as nice and chunky, and the case wears beautifully.

On balance, owners and reviewers appreciate the CWC (Cabot Watch Company) RN81 Diver Automatic Watch for its faithful homage design and solid construction, despite some reservations about its finishing and price point.
