Strap for Speedmaster Co-Axial Yellow Gold / Black / Olympic Collection

The lug width is 21 millimetres. Verify before purchase by inserting a digital calliper between the lugs of the case, where the strap rests. Precise measurement is essential to avoid incompatibility and ensure uniform contact with the watch.

Vegetable-tanned alligator is the natural choice for this model: the fine grain and light brown patina harmonise perfectly with yellow gold. Shell cordovan represents a sophisticated alternative thanks to its intrinsic lustre, while dark-toned vegetable-tanned calf offers discreet elegance and versatility.

Use a spring bar tool to gently lift the spring bar pin that secures the strap to the case. Press the tool against the spring from inside the lug, extract it completely, then remove the old strap. Insert the new strap by aligning the holes, reposition the spring bar pin by pushing until it clicks definitively into place. Check that the strap is secure on both sides.

Yes, provided it is made with a certified 21mm lug width. Avoid straps with lugs that are too narrow or too wide, which cause lateral play or prevent insertion. Choose manufacturers that guarantee precise tolerances and quality spring bar pins. A custom artisanal strap offers the advantage of perfect adjustment to your specific case.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years with regular wear and proper maintenance. Longevity depends on sun exposure, humidity, cleaning frequency, and the pressure exerted by the watch's weight. A fine leather artisanal strap, properly cared for, can reach 7-10 years of life. Protect the strap from prolonged moisture and apply natural balms every 6-12 months.
