The Ventura H24625330, seen from the bench

The Ventura was introduced by Hamilton in 1957 with the characteristic asymmetrical triangular case. It is powered by the automatic H-10-S caliber with hour, minute, second functions and a skeletonized dial. The lugs measure 23.50mm in width.

Frequently asked questions

What is the lug width of the Hamilton Ventura H24625330?

The Hamilton Ventura H24625330 features a 24mm lug width, a non-standard dimension dictated by the watch's distinctive triangular asymmetrical case geometry. This specific measurement requires careful consideration when selecting an aftermarket strap to ensure proper fit and visual integration with the case design.

Which type of strap is best suited for the Ventura H24625330?

For the Ventura H24625330, we recommend alligator straps with pronounced natural grain to emphasise the contrast with the case's rigorous geometry, or vegetable-tanned calf leather for timeless elegance. For those preferring practicality, a heavy cotton NATO or FKM rubber strap maintains the futuristic accent of the original design.

How do you change the strap on a watch with an asymmetrical lug like the Ventura?

Strap replacement requires a dedicated tool to extract the retaining pins from the asymmetrical lugs. Given the Ventura H24625330's particular geometry, it is advisable to consult a professional or follow detailed guidance to avoid damaging the case. Milano Straps provides straps with specific assembly instructions.

Are third-party straps compatible with the Hamilton Ventura H24625330?

Yes, provided they respect the 24mm lug width and are adapted to the case's asymmetrical geometry. Not all standard straps fit the Ventura perfectly due to its irregular attachment design. Milano Straps offers bespoke solutions specifically calibrated for this model.

How long does a leather strap last on the Hamilton Ventura H24625330?

Durability depends on material and usage: quality vegetable-tanned calf maintains elasticity and resistance for 4-5 years with periodic maintenance, whilst alligator, being softer, requires protective treatment and lasts 3-4 years. A heavy cotton NATO exceeds 8 years. Daily wear and moisture exposure accelerate natural leather ageing.
