Frequently asked questions

What is the exact lug width of the CODE41 Anomaly-01 AN01-BK-ST-PER-BE?

The lug width of the CODE41 Anomaly-01 AN01-BK-ST-PER-BE is 24mm. This width is specifically calibrated to the proportions of the 42mm case and ensures perfect aesthetic integration. To verify the measurement correctly, use a digital calliper positioned perpendicularly to the case, from the inner centre of one lug to the inner centre of the other, excluding any decorative elements.

Which type of strap do you recommend for the CODE41 Anomaly-01?

For the CODE41 Anomaly-01, we recommend vegetable-tanned leather straps (alligator or satin calf) for formal contexts, as their natural texture does not compete visually with the mechanical skeleton of the case. For everyday use, NATO-style straps in technical fabric keep the steel as the protagonist. If the destination is sporty or aquatic, vulcanised FKM rubber guarantees superior water-repellent performance whilst maintaining aesthetic coherence with the industrial design of the visible movement.

How do you change the strap on a CODE41 Anomaly-01?

Strap replacement is performed using a dedicated spring bar tool for watches. Locate the small metal springs (spring bars) that connect the strap to the case lugs. Insert the tool into the appropriate notch to compress the spring, then gently remove the old strap. Repeat the operation on the other side. Insert the new strap aligning it with the lugs and allow the springs to lock automatically. Ensure both sides are securely anchored before wearing the watch.

Can I use an aftermarket 24mm strap on this model?

Yes, any strap with a 24mm lug width is compatible with the CODE41 Anomaly-01 AN01-BK-ST-PER-BE. The watch enthusiast community has developed high-quality artisanal straps in this size, from specialist brands to bespoke productions. Always verify that the strap has the correct spring bar hole dimensions (standard 1.5mm) and that the thickness does not exceed 4mm, to ensure clean insertion into the lugs.

How long does a vegetable-tanned leather strap last on a daily-wear watch?

A quality vegetable-tanned leather strap, subjected to moderate daily wear (5-6 days per week), has an average lifespan of 18-24 months before replacement is required. Longevity depends on usage intensity, environmental humidity and tanning method. Alligator or shell cordovan straps last longer (24-36 months) thanks to greater natural leather density. Regular maintenance with natural wax extends the lifespan by 30-40%. NATO and FKM rubber straps have longer durability (3-5 years), as they do not degrade hydrologically like natural leathers.
