SEIKO SUPER hand-wound watch, an antique. - Brand: SEIKO - Model: SUPER - Material: Stainless steel This is the SEIKO SUPER, a commemorative model featuring the first three hands (hour, minute, and second) in Japan. It's an antique wristwatch from the 1950s. This model has the S mark and the crane mark. Before listing, I wound the watch and, using a flat-lay method, measured it myself, and it was about 1 minute fast per day. It's currently running smoothly, but please understand that it is an old item, so there may be some issues. As far as I remember, I acquired it about 7-8 years ago and used it a few times before storing it. This is being listed as part of my end-of-life preparations. Thank you for looking.
