Strap for TE8

The lug width of the 1SJAR.G01A.C112A is 20 millimetres. This measurement represents the internal distance between the two lugs of the 18k red gold case and is the fundamental parameter for determining compatibility with aftermarket straps. Precise measurement with a digital calliper ensures a perfect fit without lateral play.

Alligator leather dyed in burgundy or cognac represents the most harmonious choice with the 18k red gold case. Alternatively, vegetable-tanned calf leather in warm mahogany offers pronounced texture and a patina that ennobles over time. For formal contexts, polished black calf with a deployante clasp is impeccable. If you prefer versatility, a NATO strap in slate grey maintains elegance without sacrificing practicality.

Strap changes are performed by extracting the spring bars of the lugs. Use a dedicated spring bar tool to apply inward-facing pressure, releasing the bar from one of the two lugs. Proceed with care to avoid scratching the red gold case. Insert the new strap by aligning the holes with the lugs, then reinsert the bars until they click into position. Verify that the strap is positioned square to the case.

Yes, any aftermarket strap with a 20mm lug width is compatible with your Arnold & Son. However, we recommend selecting manufacturers that guarantee elevated constructive quality: premium leather, precise stitching, and finishes that respect the excellence of your red gold case. Artisanal straps in vegetable tanning or alligator maintain aesthetic and functional value over decades, unlike budget solutions that degrade rapidly.

A high-quality leather strap (alligator, vegetable-tanned calf) lasts on average 3–5 years with daily use, and over 10 years with intermittent wear. Longevity depends on factors such as UV exposure, ambient humidity, frequency of wear, and maintenance care. A vegetable-tanned strap develops an increasingly beautiful patina with natural ageing, transforming wear into character. The clasp and spring bars require periodic inspection to prevent sudden failure.
