Strap for Essence Leggera Automatic Chronometer Electric Blue / Calf

The Formex Essence 0330.4.6339.714 features a 22mm lug width. This is the standard dimension for medium to large-sized wristwatches and provides access to an extensive range of aftermarket straps without requiring any mechanical adaptation. To verify correct compatibility, measure the internal space between the two lugs perpendicular to the case.

The choice depends on intended use: for everyday elegance, we recommend vegetable-tanned calf leather or fine-grain alligator; for sports and diving activities, a high-tensile nylon NATO strap; for maximum versatility, structured FKM rubber. All these materials integrate flawlessly with the hybrid titanium, ceramic and carbon case construction.

Use a dedicated spring bar tool to compress the lug springs and remove the old strap from the case ears. Align the new 22mm strap and gently reinsert the springs into their seats. Ensure the strap is securely fastened before wearing the watch. If unsure, consult a professional watchmaker.

Yes, the 0330.4.6339.714 accepts any aftermarket strap with a 22mm lug width. You can choose from dozens of options: vegetable-tanned leather, alligator, shell cordovan, NATO, rubber, silicone. Milano Straps offers a complete collection of straps certified for this size, with fast shipping and custom personalisation available.

A quality leather strap (vegetable-tanned calf, alligator, cordovan) typically lasts 3–5 years with daily use, depending on exposure to moisture, perspiration and UV rays. Vegetable-tanned leather develops a beautiful patina over time. To extend strap life, apply dedicated balms occasionally and avoid prolonged water immersion. NATO and rubber straps offer greater durability in extreme environments.
