Zenith
Defy 6.9200.670/01.MI001— lug 22mm

The lug width of the Zenith Defy 6.9200.670/01.MI001 is 22mm. This specification determines compatibility with aftermarket straps: the distance between the lugs must be exactly 22mm to ensure secure and proportionate attachment to the case.

For the 36mm Defy, we recommend three options: Mississippi alligator for maximal elegance with natural patina evolution over time; Florentine vegetable-tanned leather for austere material character and visible ageing; satin-finished calf leather for balance between formality and daily practicality. The choice depends on usage context and personal preference for durability versus minimalist aesthetics.

Use a dedicated tool (spring bar tool) to remove the elastic tappets that secure the strap to the lugs. Insert the flat tip of the tool into the small lateral space of one tappet, release the tension, then extract the old strap. Insert the new strap aligning the holes to the 22mm diameter specification, then reinsert the elastic tappets until the safety click is felt.

Yes, provided the lug width is exactly 22mm as specified for this model. Always verify the dimensions stated in the strap's technical sheet before purchase. Milano Straps designs all straps to this tolerance and tests compatibility with the Zenith attachment system.

The lifespan of a leather strap depends on daily usage, climate conditions, and maintenance. A quality alligator strap with traditional vegetable tanning lasts 4-6 years before requiring replacement due to natural wear. Leather ages visibly and develops patina: this is constructive character, not defect. The Milano Straps warranty covers manufacturing defects for 18 months.
