Strap for Classique Minute Repeater Perpetual Calendar White Gold / Silver

The lug width of the Breguet Classique Complications 5447BB/1E/9V6 is 18 mm. This measurement is taken with a digital calliper positioned on the inner edges of the case lugs and is the key parameter for selecting a compatible strap. All 18 mm straps available on MilanoStraps are compatible with this reference.

For the white gold case of the Breguet Classique Complications 5447BB/1E/9V6, a vegetable-tanned alligator strap is the most coherent choice both aesthetically and sartorially. The natural belly grain of alligator leather engages visually with the hand-guillochéd dial. Alternatively, shell cordovan develops a highly individual patina over time, suited to those who prefer a more understated character. A white gold deployant clasp completes the ensemble without chromatic discontinuity.

The strap on the Breguet Classique Complications 5447BB/1E/9V6 is changed using a fine-tipped spring bar tool. The 18 mm spring bars must be compressed laterally to release them from the case lugs. It is advisable to work on a soft surface to protect the dial and white gold case from scratches. If in doubt, consult a professional watchmaker or the Casati Milano atelier for a specialist service.

Yes, any strap with an 18 mm lug width is technically compatible with the Breguet Classique Complications 5447BB/1E/9V6. MilanoStraps offers a selection of handcrafted straps — in alligator, shell cordovan and vegetable-tanned calf — produced to measure for this lug size. Quality aftermarket straps respect the same aesthetic principles as the original strap, often with greater scope for customisation in terms of stitching and finish.

The lifespan of a leather strap depends on the material, frequency of use and level of care. A quality vegetable-tanned alligator strap, worn with care to avoid moisture and rotated with other straps, can last between three and five years while retaining good structural integrity. Shell cordovan, thanks to the compactness of its fibre, tends to last even longer, developing a distinctive patina over time. MilanoStraps provides an 18-month guarantee against manufacturing defects on all Casati Milano straps.
