Breguet introduced an updated Marine collection at BaselWorld 2018, building on the look that was introduced with the 2017 Marine Équation Marchante 5887. Reference 5517TI/Y1/5ZU has a Titanium case of 40.00mm and a Blue dial with applied Roman numerals. It is powered by the self-winding caliber 777A. This version was added to the collection in 2021.
