The Ventura H24301141, seen from the bench

The Ventura was introduced by Hamilton in 1957 as the world's first electric watch with an asymmetrical triangular case. It is powered by the ETA F05.111 quartz movement with hour, minute, second and date indications. The case features 17mm lugs and maintains the original geometric design of the 1950s.

Frequently asked questions

What is the lug width of the Hamilton Ventura H24301141?

The lug width of the Hamilton Ventura H24301141 is 17 mm. This unconventional measurement is determined by the asymmetric geometry of the triangular case. Using a digital calliper positioned perpendicularly between the lugs, the distance should measure exactly 17 mm. Standard 16 mm or 18 mm straps will not fit correctly and would compromise the visual harmony of the design.

Which strap is most suitable for the Hamilton Ventura H24301141?

For the Ventura H24301141, we recommend a strap in alligator with vegetable tanning or regenerated calf leather in neutral tones (black, navy blue, cognac brown). These materials provide discreet elegance without over-saturating the already distinctive case geometry. A stainless steel deployante ensures stability and comfort during strap changes. For active wear, a heavy cotton NATO strap or FKM rubber offers durability without adding perceived weight to the wrist.

How do I change the strap on my Hamilton Ventura H24301141?

To change the strap, position the watch on a soft cushion with the case facing upwards. Locate the spring bars securing the strap to the lugs (one on each side). Using a spring bar removal tool, gently press the bar from one end whilst extracting it completely from the other. Remove the old strap, align the holes of the new strap with the spring bar positions, and reinsert the bars ensuring they click firmly on both sides. Avoid forcing to prevent damage to the delicate lugs of the triangular case.

Can I use an aftermarket strap compatible with my Hamilton Ventura H24301141?

Yes, you can use any aftermarket strap with a 17 mm lug width. Milano Straps offers a complete collection of handcrafted straps in leather, NATO and rubber, specifically selected for watches with 17 mm attachments. Always verify that the strap has correctly aligned holes at 17 mm before purchase. Customisable straps available online allow you to select materials, colours and finishes that match your personal style.

How long does a leather strap last on my Hamilton Ventura H24301141?

A quality leather strap (alligator or vegetable-tanned calf) on an H24301141 typically lasts 3–5 years with moderate daily wear. Durability depends on: frequency of wear, moisture exposure, care and maintenance. Vegetable-tanned leather develops a natural patina over time, visually documenting your personal bond with the watch. Occasionally applying leather-specific balms extends its lifespan. FKM rubber straps have superior durability (5–7 years) as they do not deteriorate with water exposure.
