I read that Cartier never bothered to patent the design he called "Vendome Lugs" but Van Cleef & Arpels did. I like how the round watch case is emphasized and the lugs are almost not part of the case design. Even more so on VC&A designs like "Lady Arpels Pont des Amoureux". Its an effect that is amplified even more on a strap rather than the bracelet.
