Strap for Constellation Co-Axial 35 Chronograph Double Eagle White Gold / Silver / Purple Alligator

The lug width measures 20 millimeters. This dimension is determined by the distance between the centers of the two attachment pins on the case. The 35mm diameter requires this specific proportion to ensure aesthetic balance and wrist comfort.

Alligator remains the noblest choice, especially in dark shades (polished black or dark brown). Vegetable-tanned calf represents an authentic alternative for those who prefer natural aging. For summer contexts, silk NATO or FKM rubber offer contemporary aesthetic versatility.

Use a spring bar removal tool (the small elastic pins) or consult a watchmaker. Position the watch with the lug side facing upward, insert the tool under the spring bar from one side, gently push to retract the internal spring and release the pin. Repeat on the other side. Installation: align the holes of the new strap with the pins and reinsert the spring bar until you feel the locking click.

Yes, provided it has exactly 20mm lug width. Any quality strap with this measurement is compatible. We recommend noble materials (alligator, calf, shell cordovan) to maintain the aesthetic value of the white gold and enhance your horological investment.

An alligator or quality artisanal calf strap lasts between 3 and 5 years with daily wear, developing a prized patina. Durability depends on sun exposure, humidity, and frequency of wear. Natural aging is desirable: the color deepens, the surface becomes enriched with marks that tell the story of use.
