Frequently asked questions
What is the lug width of the CODE41 Anomaly-01 AN01-IN-BK-ST-ALIG-BK?
The lug width of the CODE41 Anomaly-01 AN01-IN-BK-ST-ALIG-BK is 24 mm. This non-standard measurement requires dedicated straps and precise measurement of the inner edges of the lugs to ensure perfect fit and smooth strap changes.
Which strap is best suited for the Anomaly-01 AN01-IN-BK-ST-ALIG-BK?
The ideal strap depends on your intended use and aesthetic preference. A deep black alligator emphasizes the technical modernity of the skeletal movement, whilst vegetable-tanned calf leather offers timeless elegance with natural patina development. For sports contexts, robust NATO fabric straps or fine-grained rubber ensure practicality without compromising readability.
How do you change the strap on a watch with 24 mm lugs?
To change the strap, insert the spring bar tool into the lateral grooves of the lugs, applying gentle pressure to release the spring. Once the spring is freed, slide out the old strap and insert the new one, ensuring the spring snaps back into its seat with an audible click. Precision is critical given the non-standard 24 mm lug width.
Are straps compatible with the AN01-IN-BK-ST-ALIG-BK interchangeable with other watches?
No. Due to the specific 24 mm lug width, straps designed for the Anomaly-01 are incompatible with the majority of watches, which use standard measurements (18, 20, 22 mm). Always verify lug width before purchasing an aftermarket strap.
What is the average lifespan of a leather strap for this model?
A quality leather strap (alligator, calf, shell cordovan) maintains full functionality for 3–5 years with regular use, depending on sun exposure, humidity, and frequency of wear. Vegetable-tanned leather develops patina and character over time, whilst root-dyed leather may show slight tonal variations. With periodic maintenance (gentle cleaning, conditioning with specialist balms), longevity extends considerably.
