Strap for Tourbillon 3357 Yellow Gold / Silver

The lug width of the Breguet Classique Complications 3357BA/12/986 is 18mm. This measurement should be taken between the two inner lugs of the case using a digital calliper or a fine millimetre ruler, rather than relying on the original strap supplied, which may present slight dimensional tolerances.

For this yellow gold tourbillon with a hand-guilloché dial, vegetable-tanned alligator leather represents the most aesthetically and technically coherent choice. Tabac, cognac or bordeaux tones complement the warm reflections of the case. Shell cordovan offers a dense grain with excellent natural patina as an alternative. A yellow gold deployant clasp is recommended to minimise mechanical stress on the original spring bars.

Strap replacement requires a fine-tipped spring bar tool. The spring bars fitted between the 18mm lugs must be compressed laterally with care to avoid scratching the yellow gold lugs. Rest the watch on a soft cloth and work under adequate lighting. For initial replacements, it is advisable to consult a watchmaker or the Casati Milano atelier.

Yes. All straps with a standard 18mm attachment are geometrically compatible with the Breguet Classique Complications 3357BA/12/986. Milano Straps offers a selection of handcrafted straps in alligator, calf leather and shell cordovan, made to standards equivalent to those of the Breguet Manufacture. It is important to ensure the aftermarket strap has a straight rather than curved end to fit correctly against the case lugs.

Longevity depends on tanning quality, daily use and care. A top-grade vegetable-tanned alligator strap, worn daily and properly maintained, typically lasts 18 to 36 months before showing significant wear at the main fold. Shell cordovan, owing to its superior fibre density, tends to last longer, developing patina rather than deteriorating. Avoiding prolonged exposure to water, excessive perspiration and direct heat will significantly extend strap life.
