What I'm asked about the Formex Pilot 1100.1.7020.213

What strap size does the Formex Pilot 1100.1.7020.213 take?

The Formex Pilot 1100.1.7020.213 needs 22 mm between the lugs, usually 18 or 20 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Formex Pilot 1100.1.7020.213 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the Formex Pilot 1100.1.7020.213?

Yes, in 22 mm leather. On a 47 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Formex Pilot 1100.1.7020.213?

A 22 mm calf strap, for every day. You'll find it ready in the 22 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

Frequently asked questions

Which strap is best for the Formex Pilot 1100.1.7020.213?

It depends on use case. For daily versatility, Tuscan vegetable-tanned leather (black or burnt brown) offers evolving patina and stable grip. For authentic operational context, cotton NATO or FKM rubber ensures tactical resistance. Alligator leather represents maximum aesthetic sophistication with certified durability.

Which aftermarket straps are compatible with the 1100.1.7020.213?

All straps with 22mm lug width are compatible. Milano Straps offers a complete selection of vegetable-tanned leather, alligator, shell cordovan, NATO, and FKM rubber in 22mm width, with customization options (colour, buckle, texture). Each strap is tested to specification for perfect fit and structural stability.

How long does a leather strap last on a watch like this?

A Tuscan vegetable-tanned leather strap has an average lifespan of 4–6 years with daily use, accounting for progressive wear at the spring bar flexion point. Alligator leather extends this to 7–10 years due to greater fibre density. FKM rubber lasts 3–4 years before stiffening. Longevity depends on ambient humidity, perspiration, and cleaning frequency.
