Strap for Defy Extreme Carbon Copper X Prix

The lug width of the Zenith Defy Extreme 10.9100.9004-5/27.I307 is 23mm. This measurement is specific to the 45mm case and is determined by the internal distance between the upper and lower lugs. It is essential to respect this measurement when changing the strap to avoid lateral play or instability.

The best strap depends on usage: for a classic elegant approach, black alligator or vegetable-tanned calf represent the optimal choices; for those preferring durability and natural patina, Japanese Shell Cordovan is unbeatable; for daily sporting use, a technical rubber or 23mm NATO strap guarantees practicality without compromise.

Strap replacement is performed by removing the spring bars from the lugs using a specific tool (spring bar tool). Insert the flat tip of the tool into the small slot of the lug, gently push downward to compress the spring bar, remove the old strap and insert the new one by aligning the holes perfectly with the lugs. Verify that the spring bar is fully inserted on both sides.

Yes, provided the strap is specific to 23mm lug width. Milano Straps supplies artisanal straps fully compatible and customisable in leather, colour, initials and stitching type. Casati Milano atelier also creates bespoke straps with direct consultation and 18-month guarantee.

Duration depends on material and usage: alligator and Shell Cordovan last 3-5 years with daily wear, developing natural patina; vegetable-tanned calf evolves over 2-3 years before requiring replacement; technical rubbers maintain properties for 1-2 years. Casati Milano atelier offers 18-month warranty and maintenance services to extend strap life.
