Strap for Element Automatic Chronograph Full Steel / Black / Croco

The lug width of the Formex Element 1200.1.8021.311 is precisely 25 millimetres. This width is the standard construction specification for this chronograph model and represents the distance between the lateral pins (lugs) of the case. Any aftermarket strap must be compatible with this specification to ensure correct fit to the case horns and mechanical stability over time.

For the Formex Element 1200.1.8021.311, we recommend alligator or vegetable-tanned calf for daily formal wear, or NATO and FKM rubber for technical and aquatic applications. The choice depends on your usage environment: exotic leathers offer elegance and natural patina development, whilst textiles and rubber ensure mechanical reliability and ease of maintenance in extreme conditions.

Strap replacement is accomplished by removing the lateral pins that connect the two lugs of the case. Use a dedicated tool (spring bar tool) to slightly depress the internal spring mechanism of each pin, then slide the old strap outward. Fitting the new strap follows the reverse procedure: position the pin inside the upper strap lug, press and insert into the lower attachment until you hear the security click.

Yes, any strap with a 25-millimetre lug width is compatible with the 1200.1.8021.311, provided the strap respects the case's construction thickness (typically between 4 and 5 millimetres). Always verify the specifications declared by the manufacturer before purchasing. Milano Straps offers a curated selection of artisanal straps that fully satisfy these technical standards.

The longevity of a leather strap depends on maintenance, frequency of use, and environmental conditions. A quality artisanal alligator or vegetable-tanned calf strap can exceed 3-5 years of daily wear, developing a natural patina over time that enhances its aesthetics. Periodic conditioning with specific creams and protection from excessive humidity significantly extend the lifespan of the strap.
