Movement: Automatic winding Color: Silver This is a vintage Orient watch, the Super Auto Swimmer PerfectSelfWinding. It is a mechanical watch (automatic/manual winding) and is said to be one of the first models developed by Orient when they created their first automatic watch, making it a very rare antique item. (The product includes only the watch itself with the strap; the stand, box, etc., are not included.) As shown in the photos, there is deterioration on the dial and scratches on the glass, but I believe it is in good condition for a surviving item. I cannot perform an accurate inspection, but I have confirmed that the second hand operates when the watch is worn and the wrist is moved, and also when the crown is manually wound. Please understand that I cannot confirm issues such as time loss or gain. The strap is a high-quality aftermarket leather strap that was attached when I purchased the watch as a used item 30 years ago, and I believe it is still usable. It was overhauled a few years ago, and there have been no malfunctions since then. I have used it occasionally until now, and it has functioned as a watch, but as it is a considerable antique, vintage, or even a curio, I cannot offer any general warranty. I would appreciate it if you understand the nature of this item.
