The Klaftenberger name is most likely the name of a retail jeweller in England. And almost certainly not the dude who made the watch. The watch (in my opinion) is Swiss made. You don’t show a picture of the mechanism, but I’m certain I am correct. The tell is that this watch has what is known as a “pin-set” feature. That is the small button on the case edge near the winding crown. When that button is pressed inward and the crown turned, the hands can be adjusted. Swiss watch manufacturers used pin setting more than anyone else. I am unable to read the stampings inside the case back, but I can see the numeral 18 which could indicate a case of 18-karat gold. I doubt the case was Swiss made. Had it been Swiss, the stamping would almost certainly be .750, the decimal equivalent of 18 karat. A better picture inside the case back may well indicate more. As to the royal warrant, this retailer paid dearly for that, and I doubt very much that he actually made watches for royalty. I think I see a date from 1888 inside the case back. The watch appears to be in excellent condition for a 137 year old watch. The case is a hunter style, and the watch is equipped with a hunter case hour hand, enabling the time to be read with the cover closed. The numerals and minutes chapter ring are of vitreous enamel, and the enamel appears to be intact. Dial is also vitreous enamel with black vitreous enamel Roman numerals and minutes chapter ring. Typically, a lot of English watches of the era do not have a maker or retailer name on the dial.
