The Breguet Marine Chronograph, reference 5829BB/8D/9ZU.DD0D, is the high-jewellery version of Breguet's sports watch, an 18k white gold chronograph set almost entirely with baguette-cut diamonds. Breguet's Marine line was born from the house's history as official chronometer-maker to the French Royal Navy, and this piece takes that nautical DNA and dresses it in Top Wesselton diamonds: the case edge, bezel, lugs and pushers carry roughly 158 baguette stones, over ten carats in all.

The dial is the detail that names this exact reference. It is mother-of-pearl, hand-engraved on a rose engine with Breguet's guilloché wave pattern, so it shimmers and shifts under light, marked with applied blued-steel Roman numerals and the brand's signature blued hands. The 15-minute chronograph sector is itself paved with 55 baguette-cut diamonds, an unusual touch that turns a functional scale into part of the jewellery.

Inside is the self-winding Breguet caliber 583Q/1, with a 48-hour power reserve, driving the chronograph, small seconds and date, visible through a sapphire caseback. It is 43mm. At Konesseur, every watch is authenticated and inspected in Dubai before listing, and the UAE's 5% VAT is a meaningful advantage on a piece at this level. See more watches to compare.
