FAQ
What is the lug width of the Arnold & Son Royal Collection 1TBAP.B01A.C113A?
The lug width of the 1TBAP.B01A.C113A is 20mm. This measurement represents the distance between the inner edges of the case lugs and determines compatibility with aftermarket straps. To verify it, measure the inner base of each lug with a calliper without removing the original strap.
Which strap is best suited for the Arnold & Son Royal Collection 1TBAP.B01A.C113A?
For the technical and formal dignity of the 1TBAP.B01A.C113A, we recommend alligator in cognac or havana tones, or shell cordovan with vegetable tanning that ages magnificently. Alternatively, fine-grained calf in black or brown. The rose gold case benefits from warm-toned straps. NATO remains practical for informal wear, vulcanised rubber for sports contexts.
How do you change the strap on a watch with 20mm lugs?
Use a springbar removal tool to gently push the lug pin downward. The pin will release from its seat and you can remove the old strap. Reinsert the new strap by sliding the pin through the lug holes, ensuring the pin is fully seated on both sides. Do not force: an authentic 20mm strap fits without excessive pressure.
Which 20mm aftermarket strap is compatible with the 1TBAP.B01A.C113A?
All straps in 20mm lug width are compatible with the Arnold & Son 1TBAP.B01A.C113A. The 20mm lug width is standard for this case. Always verify that your chosen strap features a deployant clasp in rose gold or compatible precious metal, and that the leather thickness (typically 3.5–4mm at the base) is proportioned to the case lugs.
How long does a leather strap last on a luxury watch like the 1TBAP.B01A.C113A?
Durability depends on material, use and maintenance. A quality alligator or shell cordovan can last 3–5 years with moderate wear and regular care (gentle cleaning, moisture protection). Calf tends to last 2–3 years. Factors such as perspiration, humidity and sun exposure accelerate ageing. A premium strap with conscious maintenance can last considerably longer, developing a patina that increases its aesthetic value.
