There are 'iced out' timepieces and then there's the Breguet Classique Double Tourbillon High Jewelry ref. 5349PT. While we are not fans of 'iced out' watches or watches with diamond accents here at WCL, we do have to recognize that this Breguet Double Tourbillon is a masterpiece of horology and high jewellery. Fitted with a massive 50 mm case and a total of 417 diamonds throughout its dial and case, this Grande Complication is simply as special as it gets, thanks to its twin rotating tourbillons.
