Swiss-made antique luxury watch. It's quite old, but it works properly. K18 hallmark present. 17 jewels. The weight, including the strap, is 9g on a household scale (amateur measurement). It's an old item, and this particular watch is rare and hard to find. How about adding it to your collection? *This is a manual-winding watch. I've confirmed that it keeps time, but I cannot guarantee against malfunctions during shipping. Please examine the photos carefully and purchase only if you understand and accept the condition.
