Strap for Day-Date 36 Yellow Gold Diamonds / President / Cognac

The lug width is exactly 20mm. This measurement represents the historical standard for Rolex 36mm classical format watches and ensures perfect proportion between case and strap. To verify, measure the distance between the internal lug pins of your case: it must be precisely 20mm.

Alligator leather (vegetable tanned if possible) represents the historical and contemporary aesthetic choice. The natural geometric grain of Mississippi or Nicaraguan alligator creates a sublime visual harmony with yellow gold, while the golden patina it develops over time enhances the metal's warmth. French calf leather is a modern alternative, softer and more versatile for chromatic pairings.

Using a dual-pronged spring bar tool, insert the pin from beneath the lug until the internal spring flexes. Slide the strap into the vacant space and gently release the tool. Repeat on the other lug. The procedure is identical for removing the previous strap. A steady hand and quality tool prevent scratches on the gold case.

Yes, provided the lug width is rigorously 20mm. Verify the seller's specifications: the width must correspond exactly, otherwise the strap will not install correctly. We recommend artisanal straps with stainless steel or gold lugs to maintain the watch's aesthetic coherence.

A quality artisanal alligator or calf leather strap typically lasts 4–6 years with daily wear, developing a characteristic and beautiful patina during this period. Longevity depends on usage, climatic conditions, and maintenance: avoid prolonged moisture exposure and treat periodically with natural balms (never silicones). Planned replacement every 4 years maintains the strap in optimal condition.
