Defy 97.9000.9004/01.R787— lug 23mm

The Zenith Defy 97.9000.9004/01.R787 features a 23-millimetre lug width. This measurement indicates the space between the two spring bars (pins) located at the lugs where the strap attaches to the case. To verify strap compatibility, measure the distance between the attachment points at the case shoulders: it must be precisely 23mm.

Your selection depends upon intended use and aesthetic preference. Vegetable-tanned alligator offers sophistication and decade-long durability; calf leather develops a compelling natural patina; heavyweight cotton NATO ensures robustness and visual versatility; FKM rubber guarantees full waterproofing during sporting activities. On a 44mm titanium watch with 23mm lugs, each material articulates a legitimate interpretation of Defy philosophy.

Obtain a spring bar removal tool (strap removal kit) or consult a qualified watchmaker. Position the watch on a soft surface, insert the removal tool beneath the lateral spring bar from the interior side, and apply gentle pressure to extract the pin. Once removed, your existing strap disconnects; align the new strap's holes with the pin positions, then reinsert the spring bars from both sides until you hear an audible click.

Yes, provided they respect the 23mm lug width specification. All straps with 23mm width attach mechanically to the case without difficulty. Custom artisanal straps permit additional personalisation: leather selection, colour choice, initial embossing, and thread colour customisation, transforming your Defy into a uniquely personal object.

A vegetable-tanned alligator strap typically lasts 10–15 years under daily wear, developing an increasingly compelling patina. Calf leather maintains full functionality for 5–8 years, after which it progressively softens and thins. Rubber exhibits variable longevity: 3–5 years of intensive use before elasticity diminishes noticeably. Climate-controlled storage and occasional cleaning substantially extend any strap's operational lifespan.
