Zenith
Defy 03.9200.670/02.MI001— lug 22mm

The lug width of the Zenith Defy 03.9200.670/02.MI001 is 22mm. This measurement is standard for this model and ensures optimal proportions between the case and strap. To verify compatibility with a strap, measure with a calliper the internal distance between the lugs that attach the strap to the case.

The best strap depends on use and context. For maximum elegance, we recommend polished or textured alligator in black or dark brown, which emphasises the faceted surfaces of the case. For a more versatile approach, vegetable-tanned calf in tan or cognac tones develops patina over time. For sports and daily wear, natural rubber or NATO fabric maintains the functional heritage of the Defy.

The strap is changed by removing the lugs using a precision tool called a spring bar tool. Position the watch on a soft surface, insert the tool into the lateral slot of the lug, push the elastic pin downwards and gently retract the pin itself. Once the lugs are freed, the strap separates from the case. The reverse operation installs the new strap. If you lack experience, entrust the operation to a professional.

Yes, 22mm aftermarket straps are fully compatible with the Zenith Defy 03.9200.670/02.MI001. Milano Straps offers a wide range of straps in alligator, calf, shell cordovan and textiles, all pre-checked for dimensional accuracy. The use of quality artisanal straps does not compromise the warranty of the movement, as the intervention concerns a removable external component.

The lifespan of a leather strap depends on the quality of tanning, frequency of use and environmental conditions. A premium alligator or calf strap, such as those crafted by Casati Milano, has a useful life of 3-5 years with daily use, during which it develops characteristic patina. Prolonged exposure to high humidity, direct heat and aggressive detergents accelerates deterioration. Regularly rotating the strap during the week significantly extends its longevity.
