The Marine 5577PT/Y2/5WV, seen from the bench

The Breguet Marine 5577PT/Y2/5WV is a platinum case model featuring the manually wound caliber 581 with tourbillon complication, housing hours, minutes and small seconds. The case measures 42.5mm in diameter with a 20mm lug width and showcases a hand-guilloché bezel characteristic of Breguet's Marine collection heritage dating to Abraham-Louis Breguet's 1815 appointment as Horloger de la Marine Royale. The 950 platinum construction provides exceptional scratch resistance and a cool, lunar tone that enhances the argenté guilloché dial.

Frequently asked questions

What is the lug width of the Breguet Marine 5577PT/Y2/5WV?

The Breguet Marine 5577PT/Y2/5WV is fitted with 20mm lugs. This measurement is determined by placing a millimeter ruler between the two lugs of the case and measuring the internal distance. All straps with 20mm attachment are compatible with this reference.

What is the best strap for the platinum Breguet Marine 5577PT/Y2/5WV?

For the 5577PT/Y2/5WV in 950 platinum, a polished black or anthracite grey alligator hornback strap represents the most coherent choice with the model's aesthetics, enhancing the cool tone of the platinum and complementing the dial's guilloché. Alternatively, vulcanized rubber with a striped texture respects the Marine collection's nautical heritage.

How do you change the strap on the Breguet Marine 5577PT/Y2/5WV?

The Breguet Marine 5577PT/Y2/5WV strap is replaced using a standard springbar system. It is recommended to use a dedicated springbar tool with a coated or nylon tip to avoid scratches on the 950 platinum case, a precious material that is sensitive to surface abrasions. In case of doubt, Casati Milano offers strap replacement service at the atelier by appointment.

Are there aftermarket straps compatible with the Breguet Marine 5577PT/Y2/5WV?

Yes, all straps with 20mm attachment are technically compatible with the Breguet Marine 5577PT/Y2/5WV. Milano Straps offers a selection of artisanal 20mm straps in various materials — alligator, box-calf leather, NATO, rubber — crafted to quality standards appropriate for a platinum tourbillon. The complete collection is available at milanostraps.it.

How long does a leather strap last on a Breguet Marine 5577PT/Y2/5WV?

The lifespan of a leather strap depends on the quality of the tanning, frequency of use, and daily care. A high-quality alligator strap, with vegetable-tanned leather and hand-stitched seams, can last three to five years with regular use. Casati Milano guarantees its straps for 18 months against manufacturing defects and provides specific maintenance guidance based on the leather type chosen.
