Frequently asked questions

What is the lug width of the CODE41 Anomaly-02 AN02-BK-ST-PER-BK?

The lug width is 24mm. This is the distance between the two spring bar attachment points on the case where the strap sits. To verify compatibility, measure the linear distance between the lugs: if your strap measures 24mm wide, it will fit perfectly into the attachment points without forcing or creating play.

Which strap do you recommend for the Anomaly-02 AN02-BK-ST-PER-BK?

For this skeletonised timepiece with satin steel case and black dial, we recommend an alligator strap in cognac or dark brown for material contrast, or black calf for formal sobriety. A dark grey NATO offers daily versatility. Your choice should reflect intended use: formal occasions warrant fine leather; sport and daily wear prefer vulcanised rubber or NATO construction.

How do I change the strap on the CODE41 Anomaly-02 AN02-BK-ST-PER-BK?

The strap is secured by two spring bars attached to the case lugs. Use a spring bar removal tool—press the bar laterally to release it—and remove the old strap. Insert the new strap into the spring bars, ensuring they click fully into place. Do not force: smooth, fluid movement indicates correct seating. This operation requires care to avoid damaging the lug holes.

Can I use aftermarket straps compatible with 24mm lug width?

Yes, any strap with a 24mm lug width is mechanically compatible with the AN02-BK-ST-PER-BK. Milano Straps specialises in 24mm straps—leather, NATO, rubber—all tested for mechanical fit and aesthetic harmony with the Anomaly-02's proportions and character. Always verify the actual width is 24mm edge-to-edge.

How long does a leather strap last on this watch?

The lifespan of a leather strap depends on wear frequency and material quality. A premium alligator or calf leather strap, with proper care (avoid prolonged water exposure; dry promptly if wet), maintains structural integrity for 3–5 years with daily wear. Vegetable-tanned leather naturally develops a rich patina. NATO and rubber straps typically last 5–7 years owing to their non-porous construction and inherent resilience.
