The Heritage

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.
Made to Measure

The strap for this watch is made to measure

On the Hamilton Ventura the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

Can a strap be fitted to the Hamilton Ventura H24525331?

The Ventura H24525331 does not accept standard straight-bar straps, as the lug attachment is an integral part of the case geometry. However, a custom-made strap tailored to the specific proportions of this watch is entirely possible: this is the specialised work of <a href="/pages/casati-booking">Casati Milano</a>, which builds the strap after taking direct measurements from the watch.

How does the custom strap construction work for the Ventura?

The craftsman at Casati Milano examines the watch during the appointment, measures the specific case dimensions, and determines the necessary width, thickness and length. The strap is then constructed as a coherent continuation of the watch's geometry, not as an accessory applied afterwards. This approach ensures perfect formal and functional harmony.

What type of leather suits the character of the Hamilton Ventura H24525331?

The Ventura requires leathers with structured texture and marked grain, reflecting the modernist intention of the case. Vegetable-tanned natural leathers that develop patina over time are ideal. Neutral tones such as dark brown, deep burgundy and black complement the design without competing with the watch's asymmetric geometry.

How long does a well-made strap last?

A strap constructed using traditional artisanal methods, in quality leather and with careful workmanship, lasts many years. Longevity depends on use, care and leather consistency: an excellent vegetable-tanned leather improves with time, developing patina and increasingly marked character, transforming wear into beauty.

Why is the skeletonised movement of the Ventura H24525331 significant?

The Hamilton H-10-S skeletonised calibre exposes the complete mechanism – gears, balance wheel, jewels – reflecting the transparency philosophy that characterised 1950s design thinking. This visibility celebrates the movement's artisanal quality and transforms the watch into a window onto Swiss precision, coherent with the case's modernist aesthetic.
