The Marine 5887BR/12/9WV, seen from the bench

The Breguet Marine 5887 is a complex timepiece featuring a 43.9 mm rose gold case and the calibre 581DPE movement. It integrates a tourbillon escapement at 5 o'clock and an equation of time complication showing the real-time difference between solar and mean time. A perpetual calendar mechanism governs hours, minutes, date, day, month, and leap year, self-correcting until 2100. Water-resistant to 100 metres with a transparent sapphire caseback, the watch features a guilloché rehaut and scalloped crown. It accommodates 20 mm straps.

Frequently asked questions

What is the lug width of the Breguet Marine 5887BR/12/9WV?

The Breguet Marine 5887BR/12/9WV has 20 mm lugs. This measurement refers to the inner width between the lugs near the case, and is the specification to provide when ordering a compatible aftermarket strap.

What is the best strap for the Breguet Marine 5887BR/12/9WV?

For a Breguet Marine 5887BR/12/9WV in rose gold with a blue dial, a polished alligator strap in navy blue or royal blue represents the most aesthetically coherent choice. Box calf leather in cognac brown is an excellent alternative for those preferring warmer tones. In marine or sports contexts, high-quality vulcanized rubber ensures functionality without compromising the character of the watch.

How do you change the strap on a Breguet Marine 5887BR/12/9WV?

The Breguet Marine 5887BR/12/9WV uses a standard 20 mm lug system compatible with traditional spring bars. Strap replacement requires a dedicated spring bar tool to remove the bars without scratching the rose gold lugs. It is recommended to have this operation performed by a watchmaker or specialized atelier, both for the delicacy of the case material and to preserve water resistance.

Are there aftermarket straps compatible with the Breguet Marine 5887BR/12/9WV?

Yes. The 20 mm lug width is a widespread standard that allows mounting high-quality aftermarket straps without any case modification. Milano Straps offers a selection of handcrafted 20 mm straps in leather, alligator, calf, rubber, and nylon compatible with the Breguet Marine 5887BR/12/9WV. For buckles, 18-karat rose gold is recommended for consistency with the case metal.

How long does a leather strap last on a Breguet Marine 5887BR/12/9WV?

A high-quality leather strap—alligator or box calf—has an average lifespan of 18 to 36 months with daily wear, varying depending on exposure to sweat, water, and UV rays. Handcrafted Milano Straps straps are covered by an 18-month warranty against manufacturing defects. To extend its life, it is advisable to avoid immersion, rotate multiple straps and periodically apply a neutral leather conditioner.
