Frequently asked questions

What is the lug width of the Formex Essence 0330.1.6341.722?

The Formex Essence 0330.1.6341.722 features a lug width of 22 mm, an engineering standard specifically calibrated for the 43 mm case. This measurement grants access to an extensive catalogue of aftermarket straps in both noble and sports materials. Measuring the lugs is straightforward: measure the internal distance between the two terminals of the spring that secures the strap to the case.

Which strap do you recommend for this Formex model?

For the Formex Essence 0330.1.6341.722, we recommend Tuscan vegetable-tanned alligator to enhance the stainless steel case's nobility, or noir or burgundy calf leather for formal contexts. Those preferring sports versatility will appreciate cotton or canvas NATO straps, whilst for humid environments, FKM rubber represents the most functional solution. Your choice depends on intended use: formal, daily, or adventurous.

How do I change the strap on my Formex Essence?

Changing the strap on the Formex Essence 0330.1.6341.722 requires a simple tool: a spring bar tool. Remove the old strap by gently grasping the spring underneath the terminal with the tool, sliding downward until released. Insert the new strap by aligning the side holes to the spring and snap back into position. We recommend working on a soft surface to prevent scratches on the case.

Are aftermarket straps compatible with my Formex Essence 0330.1.6341.722?

Yes, all straps measuring 22 mm lug width are compatible with the Formex Essence 0330.1.6341.722, provided they conform to international standards. Milano Straps offers a specialised catalogue of 22 mm straps in leather, NATO, and rubber, tested for compatibility and durability. Always verify that the side springs are in good condition before fitting a new strap.

How long does a leather strap last on a wristwatch?

A quality leather strap, such as vegetable-tanned alligator or Tuscan calf, maintains optimal functionality for 3-5 years of regular wear. Durability depends on climate (humidity shortens lifespan), frequency of wear, and care: dry the strap after water exposure, avoid prolonged sunlight and occasionally apply specific balms to extend longevity significantly. Preventive maintenance transforms the strap into a true travel companion.
