Zenith
Defy 16.9200.670/03.MI001— lug 22mm

The lug width of the Zenith Defy 16.9200.670/03.MI001 is 22 mm. This measurement is taken between the inner shoulders of the case lugs, and it is essential for ordering a compatible strap. To verify the measurement, use a digital calliper positioned between the two grooves where the strap is inserted.

For the Defy 16.9200.670/03.MI001, we recommend alligator straps (especially Nile varieties with fine grain), vegetable-tanned calf leather for chromatic evolution over time, or ballistic canvas NATO straps for a more contemporary and sporty look. The choice depends on the context of use: formal settings suit alligator and calf, whilst casual and sport scenarios work well with NATO and rubber.

To change the strap, use a spring bar tool to gently lift the spring mechanisms located inside the lugs. Insert the flat tip of the tool into the lateral groove and apply steady pressure until the spring releases. Remove the old strap, align the shoulders of the new strap with the lugs, and snap the springs back into their seats. Verify that the strap is secure before wearing the watch.

Technically yes, any strap with a 22 mm lug width is compatible. However, the Defy deserves an artisanal, high-quality strap: genuine leather (alligator or calf), precise double stitching, and solid deployante clasps. Generic straps in cheap leather or synthetic materials diminish the tactile and visual experience of a movement-focused timepiece of this calibre.

Durability depends on leather quality and usage patterns. A high-quality alligator strap with natural tanning lasts 5 to 7 years in daily use, developing a fascinating patina over time. Vegetable-tanned calf has a similar lifespan of 4 to 6 years, as the softer leather is subject to accelerated wear from perspiration and friction. Rubber and synthetic NATO straps typically last 3 to 4 years. Regular maintenance—cleaning and occasional conditioning—significantly extends longevity.
