Strap for Essence Automatic Chronometer Black / Rubber

The lug width of the Formex Essence 0330.1.6321.910 is 22mm. This measurement represents the distance between the spring bars that secure the strap to the case. It is essential to verify this dimension before purchasing any aftermarket strap to ensure perfect compatibility.

The Formex Essence 0330.1.6321.910, with its minimalist Scandinavian-inspired design, is elevated by high-quality vegetable-tanned leather straps in neutral tones such as midnight blue or chocolate brown. Technical NATO straps and structured rubber represent equally authentic alternatives that emphasise the instrument's functional character.

Changing the strap is a straightforward operation: obtain a spring bar tool, position the lever beneath the lug pin and gently lift to release the internal spring. Once the pin is extracted, the old strap detaches. The new 22mm strap is aligned by its lateral holes, and the pin is reinserted. Perform this procedure with care to avoid damaging the case.

Absolutely. Any strap with a 22mm lug width is compatible with the Formex Essence 0330.1.6321.910. MilanoStraps curates a selection of artisanal straps in 22mm: vegetable-tanned Tuscan leather, alligator, shell cordovan, military NATO and vulcanised rubber, all ready-to-wear with brushed steel fittings compatible with this model.

The durability of a leather strap depends on daily usage and leather quality. A strap in high-quality vegetable-tanned leather, such as those from MilanoStraps, typically endures 3-5 years with regular wear before showing significant signs of ageing. Sun exposure, perspiration and chemical treatments accelerate deterioration. The patina that develops over time is nonetheless integral to the charm of natural material.
