The lavishly decorated case and the enamel scenes are of highest quality, underlining the fine craftsmanship of 19th century watchmaking in Geneva. The two cases are conceived for the watch to be used either "open" and showing the dial or "closed" showing the back of the inner case, hence the designation "Cabriolet". The case and frame are of such outstandingly high quality, allowing the inner case to fit so perfectly into the outer case, that the two sides show virtually no difference, neither visible nor tangible, when used as hunter case. The work can be attributed to Frères Melly, often collaborating with Blondel, specialized in the manufacture of watches for the Ottoman Market.
