I think one would be hard pressed to find a classic 6105 diver in this condition for this price that's as "plug & play" as this. That's all you'd have to do. Seiko 6105-8000 manufactured March 1969.
Model number: L5.655.4. This quartz watch is currently functioning properly. On the upper and lower right edges of the dial, there are slight peeling areas that are barely noticeable when worn. Dial color: Blue.
Condition Report: The watch presents very well on the wrist, largely due to the high-polish finishing from Patek Philippe. Because of the reflective finish, it is difficult to fully capture in photos, but there are light surface scratches on the case, as well as a small dent around the 7 o’clock position.
This is a bold, large-format Diesel watch with the signature Only The Brave case-back artwork. Collection: Only The Brave. The watch needs a new battery and is being sold as-is. No box, paperwork, or extra bracelet links are included.
