Frequently asked questions

What is the lug width of the Zenith Defy 32.9005.9004/05.R944?

The Zenith Defy 32.9005.9004/05.R944 features a lug width of 23mm. This measurement, specifically calibrated for the 44mm case proportions, requires careful consideration when selecting an aftermarket strap. To verify accurately, measure the distance between the inner lug attachments, perpendicular to the case body.

What is the best strap for the Zenith Defy 32.9005.9004/05.R944?

Alligator leather represents the most coherent choice with the Defy's aesthetic identity: its natural grain dialogue with the case's angular geometries. A sophisticated alternative is vegetable-tanned calf, which develops a noble patina over time. For a sportier approach, a technical canvas NATO or vulcanised rubber amplify the chronograph's functional vocation.

How do I change the strap on the Zenith Defy 32.9005.9004/05.R944?

Strap replacement requires a dedicated spring bar tool, available from specialist retailers. Position the watch on a work base, locate the lug pins and gently compress the internal spring using the tool, extracting the old strap and inserting the new one. If inexperienced, entrust the task to a certified watchmaker to avoid case damage.

Can I fit a made-to-measure aftermarket strap with 23mm lug width on the Zenith Defy 32.9005.9004/05.R944?

Yes, provided the strap has been manufactured specifically for 23mm lug width and correctly executes the connection with the case pins. Milano Straps offers an extensive selection of straps compatible with this width. For total customisation, the Casati Milano atelier creates bespoke straps to measure, with direct leather selection and personalised finishes.

How long does a natural leather strap last on a wristwatch like the Zenith Defy?

A natural leather strap, subject to daily wear, has a lifespan of 4-6 years with proper maintenance. Factors such as humidity, direct sunlight exposure and intensity of use influence longevity. Vegetable-tanned straps age more nobly, developing a unique patina. Casati Milano provides an 18-month guarantee on bespoke straps, covering manufacturing defects and abnormal wear.
