The Ventura H24604330, seen from the bench

The Ventura was introduced by Hamilton in 1957 as the world's first electric watch, characterized by its distinctive triangular case. It features the automatic H-10 calibre with hour, minute, second and date functions. The case has 23.50mm lugs and represents an example of the avant-garde design of the 1950s.

Frequently asked questions

What is the exact lug width of the Hamilton Ventura H24604330?

The lug width of the Hamilton Ventura H24604330 is precisely 24 mm. This measurement represents the distance between the two lateral pins of the case where the strap attaches. It is essential to verify that any strap purchased is compatible with this specific width, as even minor variations would result in functional incompatibility.

What is the best strap for the Hamilton Ventura H24604330?

There is no single 'best' strap, but recommended choices depend on your intended style. For formal elegance, an alligator strap in black with a stainless steel deployante clasp enhances the asymmetrical geometry. For everyday wear, a vegetable-tanned leather strap develops a rich patina over time. For those seeking sportive practicality, a NATO textile strap or technical rubber strap maintains the modern character of the piece.

How do you change the strap on the Hamilton Ventura H24604330?

Changing the strap requires a specialised tool (spring bar tool or lug width extractor). You must gently push the spring bar pin from the opposite side inward to release the previous strap, then insert the new strap and reinsert the pin. If you lack experience, it is advisable to have a professional watchmaker perform the operation to avoid damaging the case.

Is a third-party 24 mm strap compatible with the Ventura H24604330?

Yes, any quality-certified strap with a 24 mm lug width is compatible with the Ventura H24604330, regardless of material (alligator, calf leather, NATO, rubber). Milano Straps supplies exclusively verified straps for this measurement, guaranteeing both compatibility and artisanal quality.

How long does a leather strap last on the Hamilton Ventura H24604330?

A high-quality leather strap typically lasts 3 to 5 years with moderate use (5-7 days per week). Longevity depends on the tanning quality, mechanical wear, and exposure to moisture. Vegetable-tanned leathers tend to last longer and develop a desirable patina. Regular maintenance and protection from perspiration and water significantly extend useful life.
