Frequently asked questions

What is the lug width of the Formex Essence 0330.1.7321.322?

The lug width of the Formex Essence 0330.1.7321.322 is 22mm. This is the precise distance between the attachment pins on both sides of the case. Verify this measurement with a digital calliper before purchasing an aftermarket strap to ensure perfect fit.

What strap is recommended for the Formex Essence 0330.1.7321.322?

For the Formex Essence 0330.1.7321.322 stainless steel 43mm case, we recommend an alligator strap of quality, shell cordovan with vegetable tanning, or opaque black calf leather for elegance. For sports use, butyl rubber or NATO cotton-polyester straps provide durability and water resistance whilst respecting the model's essential aesthetic.

How do I change the strap on my Formex Essence 0330.1.7321.322?

Place the watch on a soft pad. Locate the spring bars on both sides of the case. Use a spring bar tool to gently press the pin, creating the necessary space. Remove the pin from its seat and take off the strap. Insert the new strap into the seat, then reinsert the pin until it clicks into place. Verify the strap is centred.

Is a 22mm aftermarket strap compatible with the Formex Essence 0330.1.7321.322?

Yes, any strap with a 22mm lug width is compatible with the Formex Essence 0330.1.7321.322. Standard attachment pins do not vary between models. However, we recommend verifying the outer diameter and the shape of the strap end (straight or curved) to ensure comfortable and aesthetic fit.

How long does a leather strap last on the Formex Essence 0330.1.7321.322?

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts 3-5 years with ordinary care: avoid prolonged moisture, intense direct sunlight, and excessive creasing. Natural patina evolves over time, increasing aesthetic value. NATO or rubber synthetic straps have longer lifespan (5-8 years) due to chemical resistance of modern materials.
