The I.N.O.X. 241724.1, seen from the bench

The Victorinox I.N.O.X. ref. 241724.1 features a 43 mm stainless steel 316L case with Swiss quartz Ronda 715 movement, sapphire crystal with anti-reflective coating, and 200 m water resistance. The black matte dial with applied indices and luminescent hands ensures tactical readability. The unidirectional black anodized aluminum bezel, geometric case edges, and screw-down crown reflect military heritage and functional design. The 21 mm lug width is the specific standard for this model, requiring precise measurement and dedicated aftermarket straps.

Frequently asked questions

What lug width does the Victorinox I.N.O.X. ref. 241724.1 feature?

The Victorinox I.N.O.X. 241724.1 is equipped with a precisely 21-millimetre lug width. This dimension is model-specific and measurable by positioning a digital calliper between the case's inner lugs. Do not accept 20mm or 22mm variants, as they would compromise strap stability.

Which strap should be chosen for the Victorinox I.N.O.X. 241724.1?

Selection depends on application. For formal contexts: black-dyed alligator or cognac vitello with vegetable tanning. For tactical or humid environments: FKM rubber with titanium deployante, waterproof and durable. For vintage military aesthetic: NATO canvas in olive drab. We recommend evaluation at Atelier Casati Milano for ergonomic personalisation.

How is the Victorinox I.N.O.X. 241724.1 strap changed?

The procedure requires specialist tools: hardened steel spring bar tool, soft work surface (felt or leather) to prevent case scratching. Position the watch horizontally, locate the guide pin (lug), gently push the spring bar tool from the opposite side until extraction. Reverse the procedure for the new strap, verifying complete pin insertion. Casati Milano offers strap-change service by appointment.

Are aftermarket leather straps compatible with the Victorinox I.N.O.X. 241724.1?

Yes, provided lug width is precisely 21 millimetres. Milanostraps.it stocks artisanal straps in various finishes (alligator, shell cordovan, vitello, vegetable-tanned leather) manufactured in Italy and compatible with this model. Always verify measurements before ordering.

What lifespan does a natural leather strap have on this watch?

A quality vegetable-tanned leather strap (alligator, shell cordovan, vitello) offers 2–4 years durability with daily wear, depending on ambient humidity and maintenance frequency. FKM rubber lasts 4–6 years. Canvas NATO resists 3–5 years. Leather's biological patina is desirable—it represents not wear but personalised character development of the object.
