Thank you for viewing. This is an ELGIN A-11 hand-wound watch. I purchased it about 3 years ago on an auction site. I am selling it because I have fewer opportunities to wear it, and I would like to pass it on to someone who appreciates it. The case diameter is approximately 30mm. I am not very knowledgeable, so the details of the age, etc., are unknown. I have not had it maintained since I purchased it, but according to the information at the time of purchase, it had been overhauled within the last year. The hand-winding function works without any problems. Please check the condition in the photos. There is some green oxidation, giving it a tasteful appearance. This is an antique item that is over 50 years old. Please understand that we cannot accept any claims after purchase, so please purchase only if you understand this. The item will be shipped as a wristwatch. Thank you for your consideration.
