Strap for Essence Automatic Blue / Rubber

The lug width of the Formex Essence 0330.1.7331.910 is precisely 22mm. This measurement represents the distance between the two lugs (case ears) and is critical for ensuring compatibility with any aftermarket strap. Always measure this distance directly on your watch to avoid specification errors.

The optimal material depends on your intended use. For formal and elevated daily wear, we recommend vegetable-tanned leather (calf or alligator), which creates a refined aesthetic pairing with the stainless steel case. For sports and humid environments, NATO and rubber straps offer superior resilience. The ideal solution is to maintain at least two complementary straps for rotation depending on context.

Strap removal is accomplished by releasing the spring bars that connect the strap to the case lugs. Use a dedicated spring bar removal tool and apply gentle pressure to dislodge the old strap. Position the new strap in alignment with the lugs and reinsert the spring bar, ensuring it is fully secured. If inexperienced, we recommend assistance from a specialised watchmaking service.

Yes, numerous aftermarket straps are compatible with the 22mm lug width specification. Milano Straps provides a comprehensive collection of hand-crafted straps in leather, NATO, and rubber, all precisely dimensioned for 22mm compatibility. Always verify with the supplier that their strap explicitly confirms 22mm lug width compatibility prior to purchase.

The durability of a natural leather strap depends on wear intensity and environmental conditions. With moderate daily use and appropriate maintenance (occasional cleaning, avoiding prolonged moisture exposure), a quality leather strap typically delivers 3-5 years of conscious wear. Vegetable-tanned leather ages beautifully, developing characteristic patina. Rubber and NATO straps generally offer superior durability in high-wear environments.
