I believe this item was manufactured between 1960 and 1964. I have not opened the back cover to check the serial number, so I cannot confirm the exact manufacturing date. Please understand. This is a so-called vintage watch (⁠◍⁠•⁠ᴗ⁠•⁠◍⁠)⁠❤ A simple silver dial and a hand-wound wristwatch with brown lizard leather. This item has been tested and is in working order. Winding the mainspring: OK Stops winding Crown operation: No problem Time adjustment possible by pulling the crown one step Accuracy has been measured using a smartphone app, but please consider it as a reference only when laid flat. Please note that we do not guarantee accuracy. The strap is a new, unused Seiko lizard strap that has been installed for the listing. The crystal and case have been polished and cleaned, and I don't think there are any noticeable scratches or stains. The dial has some scratches and stains due to aging. Well, personally, I think it has aged nicely (⁠。⁠・⁠ω⁠・⁠。⁠)⁠ノ⁠♡ - Color: Silver - Strap Material: Lizard leather - Strap Color: Brown - Dial Design: Simple - Function: Hand-wound Thank you for viewing.
