Strap for Golden Ellipse 5738 White Gold / Arabesques and Volutes

The Patek Philippe Golden Ellipse 5738/51G-001 features a 20-millimetre lug width. This is a specific, non-standard measurement that reflects the proportions of the 34.50-millimetre elliptical case. Correct measurement is performed with a digital calliper on the internal lug shoulders, parallel to the case.

For the 5738/51G-001 in white gold, genuine alligator is the most harmonious choice: its fine grain and natural tonality enhance the white gold's subtle luminosity without visual conflict. Recommended colours: dark brown, deep black, or grey-tortoiseshell. Vegetable-tanned calf leather is a valid alternative for those who appreciate natural patina. Avoid rubber and textile straps — this model demands refined construction.

Remove the watch and place it on a soft surface (velvet cloth). Locate the spring bars at both ends of the lugs. Using a spring bar tool, insert the tip into the groove and gently loosen to release the bar downward, then extract the lug pin from the case lug. Repeat on the opposite side. Insert the spring bar of the new strap and ensure the click is secure on both sides before wearing.

Yes, provided it meets three criteria: 20-millimetre lug width, noble materials (alligator, calf, shell cordovan), and a deployant clasp in 18-carat white gold or white steel — never mixed metal. Casati Milano straps are Italian-made to these specifications and include an 18-month warranty. Always verify correct measurement before purchase.

Durability depends on material and wear: genuine alligator resists 5–7 years with daily use, vegetable-tanned calf 4–5 years, shell cordovan 6–8 years thanks to its natural density. Patina improves in the first 2 years and the strap ages naturally without degrading. Protect the strap from prolonged water and humidity exposure to maximise longevity. A Patek Philippe deserves attentive care.
