The Ventura H24551131, seen from the bench

The Ventura was introduced by Hamilton in 1957 as the world's first electric watch, characterized by its asymmetrical triangular case. It is powered by the ETA F06.111 quartz calibre with indications of hours, minutes, seconds and date. The H24551131 reference maintains the distinctive original design that made it famous in 1950s cinema.

Frequently asked questions

Can I fit a standard strap on the Hamilton Ventura H24551131?

No, the bracelet is integrated into the case with an asymmetrical proprietary attachment. A standard strap won't fit. That's where <a href="/pages/casati-booking">Casati Milano</a> comes in: I craft the strap directly to your case's geometry, respecting that shield shape which tolerates no compromise.

How does the bespoke strap process work for the Ventura?

I work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>. I take measurements directly from your case, tracing the asymmetrical lugs and hand-shaping the strap as an organic extension of the case. It's not a generic solution—it's built for your specific watch.

Which leather do you recommend for the Hamilton Ventura?

I prefer Barenia. This watch carries a sporting yet refined character, designed in 1950s America, and Barenia ages into a warm patina that honours that timeless modernity. It develops depth over years.

How long does a well-made strap last?

With mindful use and regular care—occasional cleaning, no prolonged moisture—a quality leather strap lasts easily 5-7 years. Barenia in particular softens and ages beautifully. The strap shouldn't be systematically stressed, but that's self-evident.

Why does the Ventura demand such precision in strap construction?

Because the form is deliberate: Richard Arbib designed it as a sculptural unit where case and lugs are inseparable. Fitting the wrong strap means betraying that geometry. Every millimetre of my work must respect that vision, otherwise you're looking at a compromised watch.
