FAQ
What lug width does the Formex Element 1200.1.8011.713 require?
The Formex Element 1200.1.8011.713 features a 25mm lug width. This is a non-standard measurement in the commercial watch market, but it follows the specific geometry of the 46mm case and ensures correct visual proportions. Lug width is measured as the distance between the spring bar holes: 25mm is the precise specification required for compatible straps without any modifications.
Which strap material is best suited for the Formex Element?
The choice depends on your intended use: a dark brown or black alligator strap enhances the technical character of the Formex whilst maintaining elegance and longevity. For sports and humid environments, a vulcanised rubber strap with a deployant clasp provides superior grip and durability. A NATO canvas in military green or black offers maximum versatility and quick-change convenience. All options must respect the 25mm lug width specification.
How do I change the strap on the Formex Element 1200.1.8011.713?
You will need a spring bar tool. Position the forked end of the tool beneath the spring bar, toward the small lateral groove on the case, and gently apply upward pressure. The bar will exit its seat, allowing you to remove the old strap. Align the new 25mm strap with the lug holes and insert the spring bars using the tool to compress them until they click securely into place on the opposite lug. Verify secure retention before wearing.
Can I fit an aftermarket strap on this model?
Yes, provided the strap is specifically manufactured for 25mm lugs. A generic 20mm or 22mm strap will not fit correctly and will compromise the visual dialogue between case and strap. Milano Straps offers a dedicated collection of 25mm straps in leather, NATO, and rubber, all pre-sized and ready to wear, with full customisation available regarding colour and material selection.
What is the expected lifespan of a leather strap on a sports watch like the Formex Element?
A high-quality alligator or calf leather strap with vegetable tanning typically lasts 3–5 years with moderate daily wear. Prolonged exposure to water, perspiration, and sunlight accelerates deterioration. Rubber and NATO straps generally resist structural failure for 5–7 years before showing significant wear. The natural patina of vegetable-tanned leather is considered desirable: every scratch and darkening documents the watch's history of use.
