Frequently asked questions

What is the lug width of the Formex Essence 0330.1.7331.100?

The lug width of the Formex Essence 0330.1.7331.100 is 22mm. This dimension is measured as the linear distance between the two metal pins that support the strap on either side of the case. It is essential to verify this measurement before ordering an aftermarket strap, as straps of other dimensions are not compatible with the case attachments.

What is the best strap for the Formex Essence 0330.1.7331.100?

There is no 'best' strap in absolute terms, but rather the choice most suited to your intended use. For everyday elegance, we recommend vegetable-tanned leather in havana brown or deep black. For water sports or dynamic environments, high-density vulcanised rubber. For versatility, a military NATO in heavy cotton. For sartorial formality, alligator with open grain. The 22mm width provides access to all these categories.

How do you change the strap on the Formex Essence 0330.1.7331.100?

Strap replacement requires a small tool called a spring bar tool, which allows compression of the pins at the strap ends. Position the tool tip in the small recess beneath the pin and apply gentle inward pressure; the pin will retract, releasing the strap. Repeat on the other side. Insert the new strap pins into the case attachments and gradually release the tool. The process takes just minutes and requires no technical expertise.

Are aftermarket straps compatible with the Formex Essence 0330.1.7331.100?

Yes, any 22mm strap is compatible with the Formex Essence 0330.1.7331.100, provided the pins are of the same standard diameter (typically 1.8mm). Milano Straps offers a complete selection of 22mm straps in various materials and finishes, all tested for compatibility. Quality aftermarket straps often improve comfort and aesthetics compared to the original strap.

How long does a leather strap last on the Formex Essence?

Durability depends on leather quality, conditions of use, and maintenance. A high-quality vegetable-tanned leather strap, with moderate use and appropriate care, lasts an average of 5-8 years before replacement is necessary. Prolonged exposure to water, salt perspiration, and UV rays accelerates ageing. Rubber and NATO, conversely, last 10-15 years without significant deterioration. Periodic maintenance—gentle cleaning and conditioning—significantly extends the longevity of any leather strap.
