Strap for I.N.O.X. Blue Rubber

The Victorinox I.N.O.X. 241688.1 is equipped with 21mm lugs. This width is standard for the model and allows the installation of any artisanal strap manufactured for the 21mm lug width. You can measure the lugs by positioning a digital calliper between the spring bars that protrude from the case.

It depends on your use case. For tactical and marine environments, a ballistic nylon or reinforced canvas NATO strap ensures maximum durability. For daily elegance, a vegetable-tanned alligator strap offers noble ageing. A gummed rubber strap is ideal if the watch faces frequent immersions. All these materials are available in 21mm cut at Casati Milano.

Strap change is accomplished via the spring bars (elastic springs) positioned on either side of the lugs. Use a spring bar tool (small dedicated tool) to compress the spring on one side and slide the pin out of its seat. Remove the old strap, insert the new one by aligning the pin with the hole and release the spring. The operation takes just minutes and requires no technical expertise.

Yes, any strap manufactured for 21mm lug width is compatible with the 241688.1. Casati Milano's artisanal straps are specifically designed and tested for this width, guaranteeing precise tolerances and elegant finishes. We advise against generic non-dimensioned straps, which may exhibit excessive play.

A quality leather strap (alligator, cordovan, artisanal calf) lasts 3–5 years of daily wear, peaking at 7–8 years if maintained. Longevity depends on exposure to moisture, sweat and UV rays. A ballistic nylon NATO strap lasts 10+ years. Casati Milano recommends rotating several straps to extend the longevity of each.
