Strap for Cosmograph Daytona Everose / Cerachrom / Black - Diamond / Oysterflex

The lug width is 20 millimetres. This measurement refers to the distance between the horizontal pins (spring bars) that connect the strap to the lugs of the case. It is a precise dimension that ensures correct fit and the proper aesthetic proportions on this 40-millimetre model.

Natural alligator leather with vegetable tanning represents the most elegant choice: the grain texture of the reptile skin enhances the brilliance of rose gold, whilst the patina that develops over time tells the story of the watch's use. Alternatively, calf leather in deep burgundy or brown shell cordovan creates maximum sophistication.

Position the watch face-down on a soft surface. Locate the spring bars (horizontal pins) at the lugs. Use a dedicated tool or a toothpick to gently compress the pin and slide out the old strap. Repeat on the other side. Insert the new pins into the new strap and rest the ends on the case lugs, releasing pressure to secure. Verify the strap is stable before wearing the watch.

Yes, provided it respects the precise 20-millimetre width. Check that the spring bars are the correct size and that the strap does not have excessive thickness at the lugs, which could create tension on the case lugs. Quality artisanal straps guarantee strict manufacturing tolerances and total compatibility.

A noble leather strap with vegetable tanning typically lasts 3-5 years of daily use, varying depending on climate, humidity and care. Prolonged water exposure reduces lifespan; frequent contact with sunscreen accelerates ageing. Natural rubber straps have greater resistance to external factors (5-7 years). The patina that forms over time is part of the beauty of an artisanal strap, not a defect.
