Strap for Essence Automatic Chronometer Dégradé / Croco

The <a href="/pages/termine-glossario/misura-ansa">lug width</a> of the Formex Essence 0330.1.6324.311 is 22 millimetres. This dimension refers to the internal distance between the spring bar attachment points and must be verified with precision using a digital calliper, measuring in the space where the spring bar engages with the case.

For the Formex Essence, we recommend straps in vegetable-tanned leather or <a href="/pages/termine-glossario/alligatore">alligator</a> in dark tones (burnt, black, cognac), which amplify the formal austerity of the case. Alternatively, a NATO strap in heavy cotton or an FKM rubber strap ensure sporty practicality whilst maintaining the minimalist profile of the Sellita SW200-1 movement.

Strap replacement requires extraction of the spring bar using a spring bar tool. Position the tool on the spring bar seat, apply gentle pressure towards the inside of the case, and slide the bar out of its hole. Repeat on the opposite side. Insert the 22mm strap into both seats and reinsert the spring bar until you hear a definitive click. Verify the strap is symmetrically secured.

Yes, any strap with a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 22 millimetres is compatible with the Formex Essence 0330.1.6324.311. Milano Straps offers an extensive selection of 22mm straps in various materials (leather, NATO, rubber), all ready to ship and customizable according to your preferred colours and tactile finishes.

The lifespan of a leather strap depends on frequency of wear and maintenance. A strap in vegetable-tanned leather or calf skin, worn daily, maintains structural integrity for 18–24 months before showing signs of fatigue (cracking, edge loosening). Constant exposure to perspiration and UV light accelerates ageing. Regular conditioning with specialist balm extends strap life by 6–12 months.
