Strap for Patrimony Self-Winding 36.5 Rose Gold - Diamond / Pink

The Vacheron Constantin Patrimony 4115U/000R-B907 has a lug width of 16mm. This measurement should be taken between the two lugs at the spring bar seat using a digital calliper for accuracy. The 16mm lug width is a deliberate design choice consistent with the 36.50mm case diameter, ensuring harmonious proportions with high-quality artisan straps.

For the rose gold 36.50mm case of the Patrimony, a vegetable-tanned alligator strap in warm tobacco brown or bordeaux represents the most aesthetically coherent choice: the natural grain and the patina that develops over time complement the warmth of the precious metal. Black matte box-calf leather is the most versatile alternative for everyday wear. In both cases, a rose gold pin buckle or a folding deployant clasp completes the ensemble.

The strap on the Patrimony 4115U/000R-B907 is secured via standard 16mm spring bars. Replacement requires a dedicated angled spring bar tool, inserted into the spring bar slot and pressed inward to release the lug. The procedure does not require opening the case and can be performed independently with proper tools, taking care not to scratch the rose gold lugs. If in doubt, it is advisable to consult a watchmaker or visit the Casati Milano atelier.

Yes. The Patrimony 4115U/000R-B907 uses standard 16mm spring bars and is therefore fully compatible with high-quality artisan aftermarket straps. Milano Straps offers a selection of 16mm straps in alligator, calf, cordovan and other materials, hand-crafted with silk or linen thread stitching, edge finishing and overall quality consistent with the manufacture standard of the watch. Compatibility refers to the attachment; the final aesthetic depends on the quality of the leathers and craftsmanship selected.

The lifespan of a leather strap depends on the quality of the tanning, care and frequency of use. A first-quality vegetable-tanned alligator strap, with regular use and periodic conditioning with a neutral cream, can last between 3 and 6 years while retaining structural integrity and developing a desirable patina. Box-calf tends to have a shorter lifespan under conditions of high humidity. Milano Straps offers an 18-month guarantee against manufacturing defects on all artisan straps.
