The Ventura H24525331, seen from the bench

The Ventura was introduced by Hamilton in 1957 with its distinctive asymmetrical triangular case. This reference H24525331 is powered by the H-10-S caliber with hour, minute and second functions and a skeletonized dial. The movement offers an extended power reserve compared to standard calibers from the brand.

Frequently asked questions

Can a standard strap be fitted to the Hamilton Ventura H24525331?

No, the bracelet is integrated into the case. The lug attachment is proprietary and standard straps won't fit. For this model I build everything bespoke directly on the watch, shaping the attachment around the unique case architecture.

How does the bespoke strap process work for the Ventura?

I work only at <a href="/pages/casati-booking">Casati Milano</a>, by appointment. I take measurements directly from the case, studying how the asymmetric geometry sits. Every attachment is handcrafted to integrate seamlessly, without forcing anything.

Which leather do you recommend for the Hamilton Ventura?

I favour Tuscan leather with vegetable tanning. This watch has a rock'n'roll and sporty soul – natural leather ages with character, developing patina over time. If you want to emphasise that avant-garde geometry, premium suede withstands daily use well and underscores the watch's rebellious character.

How long does a well-made strap last?

With a strap built using traditional methods, expect 5-7 years of daily wear. It depends on how you treat it: protect from prolonged rain, dry it if it gets wet, let the leather breathe. Tuscan leather especially improves with age – it becomes softer and the patina tells the story.

Why does the Ventura require bespoke craftsmanship?

The Ventura was designed by Richard Arbib in 1957 as a total break from the round forms of classical watchmaking. That triangular asymmetric silhouette won't tolerate standard attachments. By building the strap bespoke, I respect the integrity of that form and let the watch remain what it is: a statement of style without compromise.
