Integrated bracelet: measurements, the most common questions, and the way to a made-to-measure strap.
Integrated bracelet
The Patek Philippe Golden Ellipse 5738/50G-023 is designed with a bracelet integrated into the case. For a compatible made-to-measure strap, the Casati Milano atelier builds it on your watch.

Frequently asked questions
Can a standard strap be fitted to the Patek Philippe Golden Ellipse 5738/50G-023?
No. The bracelet is integrated into the case: there are no standard lugs to attach a strap to. The connection is part of the watch's geometry itself. The only option is to build a strap from scratch, directly on the case.
How does the bespoke strap service work for this model?
I work on this watch exclusively through <a href="/pages/casati-booking">Casati Milano</a>, by appointment, at Via XX Settembre 15 in Milan. I take measurements directly from the case at the bench, curve by curve. I don't work from photographs or data sheets — every attachment is shaped by hand on the original watch.
Which leather do I recommend for the Golden Ellipse?
Alligator, always. The Golden Ellipse is a watch of intellectual understatement — it doesn't demand attention, it earns it. Alligator has the same logic: a natural, dense texture that ages with character without ever being loud. On white gold, I prefer midnight blue or slate grey alligator — it speaks to the restraint of the case without dulling it.
How long does a well-made strap last?
With normal care, a quality alligator strap lasts five to eight years. The key is to let it breathe: don't wear it two days running, keep it away from water and direct heat. Leather doesn't deteriorate — it transforms. Over time it develops a patina that tells the story of use, and that is one of the finest things I have seen at the bench.
Why is the elliptical shape of the Golden Ellipse so difficult to replicate in a strap?
The Golden Ellipse is designed according to the golden ratio: the curves are not symmetrical in the classical sense — they follow a precise mathematical proportion. This means every attachment must adapt to a geometry that shifts progressively along the case profile. You cannot cut a standard strap and hope it integrates. It must be shaped point by point, by hand.
