Collectors value this reference for its fruit-shaped case construction, featuring 18k gold and translucent red guilloché enamel over an engine-turned ground. The movement is a fire-gilded brass verge caliber with a fusee and chain, typical of the Fleurier style intended for export. The white enamel dial includes Roman numerals and gold spade hands, protected by a hinged cover. On the secondary market, these timepieces typically command prices in the mid-five-figure to low-six-figure range depending on enamel preservation. A notable auction result occurred at Christie’s in 2013, where a similar apple-form Bovet realized approximately $150,000. These watches are often found in pairs, as was the custom for the Qing dynasty imperial court, though single examples remain highly sought after for their mechanical and decorative condition.", "score": 198}, {"slug": "audemars-piguet-royal-oak-concept-26630", "brand": "Audemars Piguet", "ref": "26630", "model": "Royal Oak Concept Tourbillon Chronograph", "case_material": "Titanium", "url": "https://mostexpensivewatches.net/reference/audemars-piguet-royal-oak-concept-26630", "description": "The Audemars Piguet Royal Oak Concept Tourbillon Chronograph reference 26630OR.GG.D340CA.01 was introduced around 2021 as a limited production model.
