At BaselWorld 2018, Breguet revealed its revamped Marine collection, taking inspiration from the 2017 Marine Équation Marchante 5887. One standout piece is the Reference 5517BR/12/9ZU, featuring a 40mm Rose Gold case and a Silver dial adorned with Roman numerals. The watch runs on the self-winding caliber 777A and was welcomed into the collection in 2018.
