Strap for Tourbillon Extra-Plat 5377 Platinum

The lug width of the Breguet Classique Complications 5377PT/12/9WU is 20mm. This is the internal distance between the two lugs of the platinum case, verifiable with a digital caliper positioned parallel to the case band. All compatible straps must measure exactly this width to ensure proper attachment without risking damage to the platinum surfaces.

For the platinum case and guilloché dial of the 5377PT/12/9WU, an alligator strap with hornback or Mississippiensis grain is the most appropriate choice for a watch of this caliber. Matte finishes in cognac, tobacco, or midnight blue complement the cool tone of platinum. Brushed calf leather in anthracite gray represents a more contemporary yet equally formal alternative. Milano Straps offers a selection of 20mm straps specifically suited to this Breguet reference.

The strap on the Breguet Classique Complications 5377PT/12/9WU is removed using a flat or pointed strap tool inserted into the spring bar hole between the lug and the strap. It is essential to use steel tools with protective coatings or plastic guards to prevent scratches on the platinum case. We recommend entrusting the first strap replacement to a qualified watchmaker or authorized Breguet dealer.

Yes, the Breguet Classique Complications 5377PT/12/9WU is compatible with any 20mm aftermarket strap with standard spring bars. Milano Straps offers a selection of handcrafted straps in alligator leather, calf, and other fine materials, made with shaped lugs to ensure compatibility with Breguet cases in the Classique line. A bespoke strap service is available through Casati Milano.

The lifespan of a leather strap depends on the quality of the leather, frequency of use, and exposure to sweat and moisture. A quality alligator strap with a calf leather core and hand-stitched seams can last three to five years with regular use if properly maintained: dry after wearing, rotate between multiple straps, and store away from heat sources. Milano Straps guarantees its handcrafted straps for 18 months against manufacturing defects.
