Spectacular antique pocket watch in solid gold in 3 colors. Three covers. 1897

Spectacular Waltham pocket watch in perfect working order. Serial number 8187339 indicating the year of manufacture is 1897. The case has 3 covers with a precious floral embossing made in solid tricolor gold (yellow gold, green gold and rose gold). On one side are the initials ZK (in my opinion). The dial is porcelain and has Roman numerals, is signed and is perfect. The case features the 14K gold contrasts, as well as those of the silversmith. It measures 43 mm with crown and 34 mm without crown. The machinery is signed and numbered. It has beautiful geometric ornaments. The operation is perfect and the case closes perfectly and hermetically.
