Strap for Marine Chronograph 5527 Titanium / Grey / Alligator

The Breguet Marine 5527TI/G2/9WV is fitted with 22mm lugs. This measurement is verified with a digital caliper at the attachment point between the two lugs, in contact with the case. All 22mm straps with end geometry compatible to the integrated lug design are suitable for this reference.

For the Marine 5527 in titanium, an alligator strap with flat grain in midnight blue or slate gray enhances the haute horlogerie character of the guilloché dial. For sporty use, vulcanized rubber in black or navy blue is the most coherent choice with the watch's marine vocation. Box Calf leather in cognac brown instead introduces a warm contrast that highlights the gilt details of the dial.

The strap is replaced by removing the spring bars housed in the lugs with a dedicated spring bar tool or fine-tipped implement. On the Marine 5527 the lugs are integrated into the case, so it is advisable to work carefully to avoid scratching the titanium. For the first replacement it is recommended to contact a watchmaker or the Casati Milano atelier to prevent damage to the finish.

Yes. Any strap with a 22mm lug width and end termination compatible with the integrated lug geometry of the Marine can be used as an aftermarket alternative. Milano Straps offers a selection of artisanal 22mm straps in alligator, calf, NATO, and rubber—crafted by Casati Milano or available online—with finishes and materials chosen to enhance the specific aesthetic of this reference.

The lifespan of a leather strap depends on leather quality, care, and use. A high-quality alligator or calf strap, kept away from excessive moisture and perspiration and treated periodically with appropriate products, can last 2 to 5 years with regular use. Casati Milano offers an 18-month warranty against manufacturing defects on all straps made in the atelier.
