Strap for Master Chronometer 36 Stainless Steel / Yellow Gold / Diamond / Blue / Strap

The lug width of the Constellation 131.28.36.20.53.001 is 20 millimetres. This width is measured by positioning a digital caliper on the inner shoulders of the case, at the attachment pins. It is the standard for this reference and guarantees complete compatibility with all 20mm straps.

For the yellow gold and stainless steel two-tone, dark brown or deep chestnut alligator represents the most coherent aesthetic choice: it amplifies the formal character and creates visual continuity with the gold. Elegant alternative: black calf with vegetable tanning, which dialogues with the steel without compromising refinement.

Changing the strap requires the use of a spring bar tool (standard watchmaking tool). Position the tool under the pin from the opposite side of the strap to be removed, gently lift to release the internal spring, extract the pin, and repeat for the other side. The reverse operation secures the new strap. If you lack confidence, a professional watchmaker takes 5 minutes.

Yes, absolutely. The Constellation 131.28.36.20.53.001 accepts any strap made for the 20mm lug width. Artisanal straps in alligator, vegetable-tanned calf, shell cordovan or rubber are completely compatible and offer greater personalization than the original bracelet.

A quality leather strap (alligator, calf with vegetable tanning, shell cordovan) typically lasts 3–5 years with moderate daily use. Durability depends on factors such as sun exposure, humidity, frequency of wear and leather care. Artisanal Milano Straps guarantee 18 months even with regular use; beyond that period, replacement is recommended to maintain aesthetic value.
