Strap for Element Automatic Chronograph Full Steel / Black / Calf

The Formex Element 1200.1.8021.322 features a lug width (ansa) of 25mm. This dimension is proportional to the 46mm case diameter and is easily measurable using a digital calliper positioned between the inner walls of the spring bar slots. A 25mm width permits a wide variety of artisanal strap options, from sophisticated alligator models to technical rubber designs.

The optimal strap choice depends on intended use and aesthetic preference. For formal occasions and versatility, high-grade alligator (Nile crocodile) offers maximum elegance; for robust daily wear, vegetable-tanned calf leather ensures durability and natural patina development; for maritime or sport environments, synthetic NATO or FKM rubber provides practicality without compromise. All 25mm-compatible models are available in customisable configurations.

Changing the strap on the 1200.1.8021.322 requires a spring bar removal tool to dislodge the internal spring bars securing the strap to the lugs. Position the tool within the lateral slots of each lug and apply gentle pressure to flex the spring bar, allowing the strap to slide free. When installing the replacement strap, align the strap holes with the spring bars and push until you hear a distinct click confirming secure attachment. If unfamiliar with the procedure, consult a professional watchmaker.

Yes, numerous specialist artisanal strap manufacturers produce options compatible with the 25mm lug width. Milano Straps curates a selection of alligator, calf leather, shell cordovan, NATO, and rubber straps—all contoured to maximise comfort and aesthetic coherence with the titanium and stainless steel case. Every strap is customisable online and ready for dispatch.

A high-quality leather strap on a Formex Element 1200.1.8021.322 typically lasts 4–8 years depending on usage, climate, and maintenance. Alligator and vegetable-tanned calf leather develop a noble patina with age. To extend lifespan, avoid prolonged exposure to fresh water, keep the strap dry, and occasionally apply strap-specific conditioner. FKM rubber offers superior durability (10+ years) in maritime or climatically demanding environments.
