Frequently asked questions

What is the lug width of the Formex Element 1200.1.8021.713?

The Formex Element 1200.1.8021.713 features a lug width of 25mm. This dimension is specific to the Element family and is determined by the geometry of its robust lugs and the visual proportions of the 46mm titanium case. Always verify the distance between the lugs manually before purchasing a strap.

Which strap is most suitable for the Formex Element 1200.1.8021.713?

For the Formex Element, we recommend African alligator with vegetable tanning as the primary choice: the natural and irregular grain creates a striking contrast with the engineering precision of the titanium case. Sophisticated alternatives include Japanese shell cordovan (which develops patina over time) and vegetable-tanned calf in natural colour. For intensive use, cotton-polyester NATO guarantees practicality without aesthetic compromise.

How do I change the strap on the Formex Element 1200.1.8021.713?

The Formex Element uses a standard 25mm lug system. To change the strap: 1) remove the watch from your wrist; 2) locate the spring bars (small metal pins) on the sides of the case; 3) use a specialized spring bar tool to push the pins out of the lugs; 4) slide off the old strap; 5) insert the new strap and push the spring bars in from both sides until they lock. If you lack experience, contact a professional watchmaker.

Is the Formex Element 1200.1.8021.713 compatible with aftermarket straps?

Yes, the Formex Element 1200.1.8021.713 is fully compatible with aftermarket 25mm straps. Milano Straps offers an artisanal selection of <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-25mm">25mm straps</a> in alligator, shell cordovan, vegetable-tanned calf and NATO, all customisable for length and buckle at the Casati Milano Atelier.

How long does a leather strap last on the Formex Element 1200.1.8021.713?

Leather strap durability depends on use and material: vegetable-tanned alligator, when properly maintained, easily exceeds 5-7 years of daily wear; shell cordovan, more resistant to abrasion, reaches 7-10 years. Synthetic NATO lasts over 10 years. Main wear manifests at the strap ends and lugs. Milano Straps offers repair and buckle replacement services on all straps sold.
