The Anomaly-01 AN01-IN-SIL-ST-PER-BK, seen from the bench

The CODE41 Anomaly-01 AN01-IN-SIL-ST-PER-BK is a 42mm stainless steel watch featuring a sapphire crystal and transparent caseback for full movement visibility. It houses the Miyota caliber 82S7 quartz movement with 24-hour subdial, small seconds, hours and minutes. The 24mm lug width maintains proportional design consistency with the case diameter, requiring precise strap compatibility where the internal distance between lugs must measure exactly 24mm.

Frequently asked questions

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

The Anomaly-01 AN01-IN-SIL-ST-PER-BK is equipped with a 24mm lug width. This measurement must be taken between the spring bars (the metal protrusions that connect the case to the strap). It is essential to verify compatibility before purchasing an aftermarket strap, as a narrower width causes micro-movements, whilst a wider width is physically incompatible.

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

For the Anomaly-01 AN01-IN-SIL-ST-PER-BK, the most appropriate choice depends on intended usage. A high-quality alligator leather or calf leather with vegetable tanning offers elegance and develops natural patina over time. For a technical-sporting profile, NATO straps in technical fabric maintain the watch's industrial character. Vulcanised rubber is ideal for those prioritising functionality and water resistance. Every material must respect the 24mm lug width.

How do I change the strap on the CODE41 Anomaly-01?

To replace the strap on the AN01-IN-SIL-ST-PER-BK, you need to use a spring bar tool. Position the tool beneath the side spring bar, apply gentle inward pressure to compress the spring, and extract the bar from the case. Repeat on both sides. Insert the new 24mm strap by aligning the side holes with the spring bars, then snap the bars into their seats. Ensure the bars are fully inserted and secure.

Are there compatible aftermarket straps available for the CODE41 Anomaly-01 AN01-IN-SIL-ST-PER-BK?

Yes, a wide range of 24mm aftermarket straps is compatible with the Anomaly-01 AN01-IN-SIL-ST-PER-BK. Milano Straps offers handcrafted straps in leather (alligator, calf with vegetable tanning), NATO, and rubber, all available in 24mm size. These straps are designed to fit perfectly with your watch's spring bars and offer various finishes and colours to personalise your instrument.

What is the lifespan of a leather strap for the CODE41 Anomaly-01?

The lifespan of a leather strap varies based on material quality, frequency of use, and environmental conditions. A high-quality leather strap, such as alligator or calf with vegetable tanning, maintains structural integrity for 3–5 years with regular use. Exposure to high humidity, intense perspiration, and thermal variations accelerates ageing. Proper care—gentle cleaning with a dry cloth and periodic conditioning—significantly extends strap longevity.
