The Twenty~4 4920G-010, seen from the bench

The Twenty~4 was launched by Patek Philippe in 1999 as a rectangular-shaped ladies' watch. It is powered by the E15 quartz caliber with hour and minute indication. The reference 4920G-010 features a white gold case with an integrated bracelet.

Frequently asked questions

Can a strap be fitted to the Patek Philippe Twenty~4 4920G-010?

Not in the traditional sense. The bracelet is integrated into the case: there is no standard lug to attach a ready-made strap. The only way forward is to build a bespoke attachment directly on the watch, at the atelier.

How does the bespoke strap process work for this model?

I work exclusively through <a href="/pages/casati-booking">Casati Milano</a>, by appointment, at Via XX Settembre 15 in Milan. I bring the watch to the bench, take measurements from the case itself, and build every attachment millimetre by millimetre. There is no other way: each Twenty~4 has its own geometry, and I respect that.

Which leather do you recommend for the Twenty~4?

For a watch with such a precise and structured architecture, I prefer Mississippi Alligator: its regular grain works well with the white gold case's integrated links. If you prefer something softer against the wrist, Premium Swift is my second choice, especially for all-day wear. Either way, the leather must be worthy of the case — no compromises.

How long does a well-made strap last?

With quality leather and proper construction, five years of daily wear is a starting point, not a ceiling. Care matters: avoid prolonged contact with water, and apply a little neutral cream each season. Alligator ages with character — over time it tells the story of the person who wore it.

Is the Twenty~4 intended only for formal occasions, or can it be worn daily?

That is precisely what I have always found interesting about this watch: the rectangular case and integrated links give it a precise but not rigid structure. It was launched in 1999 with the idea of accompanying an active woman, not just someone attending a dinner. I keep that in mind when I build the strap: it must be elegant, but not delicate.

The next step

The right strap isn't chosen. It is built, together.
