The Heritage

The Breguet Marine 5887PT/Y2/9WV is a platinum watch that combines nautical tradition with advanced haute horlogerie complications. Housed in a 43.9 mm platinum 950 case, this timepiece features the caliber 581DPE movement with a tourbillon, perpetual calendar, and equation of time complication. The 20 mm lug width accommodates compatible straps, with the case designed to integrate these demanding mechanical functions while maintaining a legible dial with Roman numerals and guilloché finishing.

FAQ

What is the lug width of the Breguet Marine 5887PT/Y2/9WV?

The lug width of the Breguet Marine 5887PT/Y2/9WV is 20 mm. This dimension is defined during the case design phase and cannot be modified. To verify it, measure with a ruler the internal distance between the two lugs, in contact with the bezel.

What is the best strap for the Breguet Marine 5887PT/Y2/9WV?

For a 950 platinum case with tourbillon and equation of time, a hornback crocodile or smooth belly alligator strap in midnight blue or black is the most coherent choice. Box-calf leather is the alternative for those who prefer a patina developed over time. All models must have a buckle in brushed steel, platinum, or titanium to respect the sobriety of the material.

How do you change the strap of the Breguet Marine 5887PT/Y2/9WV?

The strap is removed using a flat-tip spring bar tool or a spring bar tool, by leveraging the spring bar housed in the lug. The lugs of the Marine 5887 have a slightly curved geometry: it is recommended to entrust the first change to a watchmaker, especially on a platinum case where incorrect pressure can scratch the metal.

Are there aftermarket straps compatible with the Breguet Marine 5887PT/Y2/9WV?

Yes. Any strap with a 20 mm lug width is technically compatible with the Breguet Marine 5887PT/Y2/9WV, provided that the end is shaped to follow the curve of the lugs. Milano Straps proposes a selection of artisanal 20 mm straps compatible with the model, with the possibility of complete customization through the Casati Milano atelier.

How long does a leather strap last on a Breguet Marine 5887PT/Y2/9WV?

The lifespan of a leather strap depends on the type of leather, daily use, and exposure to sweat and atmospheric agents. A quality alligator strap, with regular use and proper maintenance (nourishing cream every 3-4 months), lasts on average between 2 and 4 years. Box-calf leather tends to develop patina more quickly but with a very personal aesthetic result. Casati Milano guarantees its straps for 18 months against manufacturing defects.
