This is a Seiko Crown. It's a hand-wound watch and is working properly. It has an extremely rare brown linen dial, which can also appear dark gray depending on the light. The combination of the brown linen dial with gold-colored hands and indices is very cool. Please consider the leather strap as a bonus. (I will remove it if you don't want it.) This is an ultra-rare and very stylish Crown. ※※ The Seiko Tomony in the 7th image is not included. Thank you.
