Strap for Constellation Master Chronometer 41 Moonshine Gold / Champagne Meteorite

The lug width of the Constellation 131.50.41.21.99.001 is 21mm. This dimension is measured between the center pins of the lugs, not the bracelet width itself. It is essential to respect this measurement in millimeters to guarantee the perfect fit between the strap and case.

For the Constellation in Sedna gold in 41mm, alligator leather with natural tanning remains the superior aesthetic choice: the geometric scales enhance the rose gold tone. Alternatively, Italian vegetable-tanned leather in dark brown or shell cordovan offer fascinating natural aging. For daily wear, silk NATO or Tropic rubber ensure durability.

The Constellation's lugs are welded to the case and not removable. The strap is replaced by removing the horizontal pins (one-off pin with a specialized tool or by a certified watchmaker). Measure carefully (21mm) before purchase and have the strap changed by a professional to avoid damage to the case.

Yes, all 21mm straps are compatible with this model. Verify that the strap respects the exact measurement and that the ends entering the lugs are correctly sized. Milano Straps offers 21mm straps customizable to your specifications.

A premium leather strap (alligator or shell cordovan) lasts 5-7 years with normal daily wear, if exposed to temperate climates. Italian vegetable-tanned leather requires occasional reconditioning. Tropic rubber lasts 3-5 years. Factors such as sweat, sun exposure, and humidity reduce longevity.
