Breguet
Classique Complications 5335PT/42/9W6— lug 18mm

The Breguet Classique Complications 5335PT/42/9W6 is fitted with an 18mm lug width. To verify this on your own timepiece, measure with a caliper the internal distance between the two lugs of the case at the strap attachment point: the correct value is 18mm. All 18mm straps in the Milano Straps catalog are compatible with this reference.

For a skeletonized tourbillon in 950 platinum, a Porosus or Hornback alligator strap in black or midnight blue tones represents the most coherent choice with the watch's formal identity. Alternatively, a cognac brown or anthracite grey box calf offers a more contemporary character while maintaining the sobriety required by a timepiece of this category. A steel or platinum deployant clasp completes the pairing without aesthetic compromise.

The strap is replaced using a dedicated spring bar tool or a very thin flat-head screwdriver to push the spring bar that connects the strap to the case lug. It is recommended to rely on a watchmaker or specialized jeweler to avoid scratches on the platinum case, a material that is particularly sensitive to surface marks. Platinum, although hard, can easily show micro-scratches on polished surfaces.

Yes. Any strap with an 18mm attachment width and adequate keeper is technically compatible with the Breguet Classique Complications 5335PT/42/9W6. Milano Straps offers a selection of artisanal leather straps in alligator, calf, and other materials with 18mm lugs, crafted to the same quality standards used for OEM straps by major watch houses. The Casati Milano atelier also creates bespoke versions tailored to the exact wrist size.

The lifespan of a leather strap depends on the tanning quality, daily wear, and maintenance care. A quality alligator strap, worn in rotation with others and protected from excessive humidity, can last three to five years while maintaining structural and aesthetic integrity. Calf leather tends to develop a natural patina after six to twelve months of regular use. Milano Straps guarantees 18 months on all Casati Milano straps for manufacturing defects.
