The Anomaly-01 AN01-BK-ST-LEA-PER-COU-SP, seen from the bench

The CODE41 Anomaly-01 AN01-BK-ST-LEA-PER-COU-SP is a Swiss minimalist watch with a 42 mm stainless steel case and Miyota caliber 82S7 quartz movement featuring a fixed 24-hour hand for extended-cycle professionals. The sapphire crystal and steel crown at 3 o'clock reflect a purist design philosophy rejecting complications and aggressive aesthetics. With 24 mm lugs, this unconventional lug width requires specialized strap selection, positioning the watch as a platform for personal customization through careful strap choice.

Frequently asked questions

What is the lug width of the CODE41 Anomaly-01 AN01-BK-ST-LEA-PER-COU-SP?

The lug width of the Anomaly-01 is precisely 24 mm. This measurement represents the internal distance between the two lugs (metal protrusions) of the case. A 24 mm lug width requires specific straps, as not all mainstream manufacturers produce passants and buckles in this dimension. To verify compatibility of an aftermarket strap, simply ensure that the internal passant has been cut to 24 mm width.

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

The choice depends on intended use and personal taste. For formal-elegant wear, an Italian or Swiss quality calfskin, vegetable tanned, in Cognac brown or deep black, paired with a satin steel deployante, is ideal. For daily-sporting use, a grey or navy NATO offers versatility and durability. Shell cordovan develops a fascinating patina over time. For marine or humid environments, vulcanised FKM rubber guarantees grip and durability without degradation.

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

The strap of the AN01-BK-ST-LEA-PER-COU-SP is removed by acting on the passants that run through the lugs. Using a dedicated tool (spring bar tool), apply gentle inward pressure to release the spring that supports the metal shaft, then carefully extract the shaft from its housing. The operation requires precision but no specialist technical knowledge. The new strap must have passants of identical width (24 mm) for the lug to fit perfectly onto the case lugs.

Are there aftermarket straps compatible with this lug width?

Yes. Although 24 mm is an uncommon dimension in the mainstream market, quality artisanal manufacturers and specialised ateliers produce straps custom-made or in stock for this lug width. MilanoStraps offers a dedicated selection of 24 mm straps in leather, NATO fabric and rubber, all compatible with the Anomaly-01. Online personalisation allows you to choose material, colour, closure type and finishes, ensuring aesthetic coherence with the minimalist philosophy of the CODE41 model.

How long does a leather strap last on the CODE41 Anomaly-01?

The durability of a natural leather strap depends on the type of tanning, intensity of use and environmental conditions. A vegetable-tanned calfskin, subjected to moderate daily use and regular but not prolonged sun exposure, maintains structural and aesthetic integrity for an average of 3-5 years. With periodic maintenance (conditioning with natural balms, air drying), durability extends. Shell cordovan resists longer due to superior fibre density, easily reaching 7-10 years. Leather naturally develops an aged patina; this does not constitute deterioration but rather aesthetic evolution characteristic of biological material.
