Strap for Constellation Quartz 24 Brushed Yellow Gold / Silver

The lug width is 18mm. This measurement is essential when purchasing aftermarket straps: a narrower lug width will leave unacceptable gaps, while a wider lug width will not fit into the case lugs. Always verify this dimension before any purchase.

Alligator remains the most conservative and iconic choice – its fine natural grain and the patina it develops maintain aesthetic consonance with the precious metal case. Alternatively, shell cordovan offers fascinating chromatic contrast (cognac or bordeaux tones) and initial rigidity that softens over time. Sport materials (NATO, rubber) are not recommended as they diminish the dressy identity of the watch.

The strap is attached to the case via spring bars. Use a spring bar remover tool to gently press the small levers that hold the bars in position, freeing them from their seat. Remove the bars from the case and from the lugs of the old strap, then repeat the operation in reverse with the new 18mm strap. If you do not have the tool, consult a professional watchmaker.

Yes, provided the lug width is exactly 18mm. Milano Straps offers Italian artisanal straps specifically compatible with this reference, available online ready for shipment.

A quality leather strap (alligator, shell cordovan, calf) can last 5–10 years with regular use. Longevity depends on frequency of use, moisture exposure, and care. We recommend not exposing the strap to prolonged water contact, storing it in dry environments, and occasionally applying protective creams specific to leather. A well-maintained strap develops a fascinating patina over time, increasing the overall aesthetic value of the watch.
