Strap for Essence Automatic Chronometer Dégradé / Calf

The lug width of the Formex Essence 0330.1.6324.722 is 22mm. This measurement corresponds to the international standard for large-diameter watches (43mm). To verify the compatibility of a strap, measure the inside of the left lug tube to the inside of the right lug tube using a digital calliper.

The Formex Essence pairs exceptionally well with leather straps in vegetable tanning (calf or alligator) that emphasise the linear design of the case. A tobacco-brown strap in traditional Florentine vegetable tanning creates warm contrast with the stainless steel. For nautical use, a dark grey NATO strap maintains coherence with Swiss heritage. Rubber is the choice for those who treat the watch as a daily-use tool without aesthetic compromise.

The Formex Essence 0330.1.6324.722 is equipped with straight 22mm lugs. To change the strap, use a spring bar tool: insert the bifid tip into the lateral grooves of the lug, compress the spring pin slightly, remove the old strap and insert the new one by snapping the pin into the grooves. The operation takes seconds and requires no specialised skills.

Yes, any strap with a 22mm lug width is compatible with the Formex Essence 0330.1.6324.722. Milano Straps artisanal straps offer a range of materials (Tuscan leather, calf, alligator, NATO, rubber) in various finishes and colours, specifically dimensioned for this lug width. The construction quality of an artisanal strap amplifies the perceived value of the Swiss watch.

A quality vegetable-tanned leather strap, exposed to normal usage conditions (avoiding stagnant water and prolonged humidity), guarantees 4–7 years of daily wear. Vegetable tanning develops natural patina and darkens over time, increasing its aesthetic value. Longevity depends on frequency of wear, climatic conditions and maintenance: occasional cleaning with a damp cloth and a coat of natural balm every 12 months significantly extends the strap's service life.
