Frequently asked questions

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

The lug width of the CODE41 Anomaly-01 is 24mm. This measurement is determined by the distance between the inner lugs of the case and remains fixed across all models in this family. A 24mm lug width is a specific standard that requires dedicated straps and is not compatible with more common sizes such as 20mm or 22mm. All straps for this timepiece must be ordered with this precise lug width measurement.

Which strap material is most suitable for the CODE41 Anomaly-01?

For the CODE41 Anomaly-01 AN01-CA-ST-PER-BK, the most recommended strap material is natural alligator leather with vegetable tanning, in antique grey or cognac brown tones. This choice establishes an aesthetic equilibrium between the industrial modernity of the hybrid case (titanium, forged carbon, stainless steel) and the constructive tradition of the strap. Alternatively, calf leather with visible grain or a rubberised fabric strap amplifies functional coherence. Material selection must reflect intended use: leather for formal occasions, rubber for dynamic activities.

How do I change the strap on a watch with 24mm lugs?

To change the strap on a watch with 24mm lugs, proceed as follows: 1) Obtain a spring bar removal tool and a new 24mm-compatible strap. 2) Position the watch on a soft pad to protect the case. 3) Insert the forked end of the spring bar tool into the access hole of the pin (inner side of the case). 4) Press gently upward to release the pin from its seat. 5) Completely extract the pin and old strap. 6) Align the holes of the new strap with the case lugs. 7) Insert the new pin in reverse sequence until you hear the locking click. If unfamiliar with the procedure, consult a professional watchmaker.

Can I use an aftermarket strap compatible with the CODE41 Anomaly-01?

Yes, any artisanal strap with 24mm lug width is compatible with the CODE41 Anomaly-01 AN01-CA-ST-PER-BK, provided constructive tolerances are correct. Artisanal straps produced by specialised ateliers, such as those offered by Milano Straps, guarantee superior material and construction quality compared to generic aftermarket alternatives. Always verify that the lug width is exactly 24mm and that the buckle (if present) is manufactured from material compatible with the hybrid case—preferably titanium or stainless steel. A well-crafted artisanal strap substantially extends the aesthetic potential of the Anomaly-01.

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

The lifespan of a leather strap depends on material quality and intensity of use. A natural alligator or vegetable-tanned calf leather strap, subjected to moderate daily wear (8-10 hours per day) in dry environments, maintains structural integrity for 2-3 years. Constant exposure to moisture, perspiration, or water reduces useful life to 12-18 months. The patina that develops on leather over time is an appreciated element among connoisseurs: it signifies authentic ageing. To maximise longevity, protect the strap from intense rain, avoid prolonged exposure to direct heat, and periodically apply leather conditioner (not oil). A high-quality artisanal strap can be restored by a specialist before it becomes unusable.
