Vintage Seiko 5 Automatic 2906-5140 Octagonal Watch

Vintage Seiko 5 automatic watch with a unique octagonal case. It features a grey dial with a day/date window that includes Arabic script. The stainless steel band is original. It's definitely seen some life—the crystal is heavily scratched and cracked, and there's general wear on the case and band. Selling as-is, likely needs a new crystal and a good cleaning.
