Strap for TEC1

The lug width of the Arnold & Son Royal Collection 1CTAG.U02A.C113G is 20mm. This dimension is determined by the geometry of the 44mm case and the distance between the attachment pins. It is essential to measure precisely between the two inner lugs to ensure strap compatibility.

The ideal strap depends on intended use: for formal elegance, a vegetable-tanned alligator in smoked brown complements the luminosity of palladium; for versatility, Italian calf leather in bruised tobacco; for sportiness, a charcoal grey NATO ribbon with a deployante buckle. The choice reflects the technical character of the watch without obscuring its mechanical complexity.

Strap replacement requires precision. Use a dedicated spring bar tool to gently push the pin from one side without applying excessive pressure to the palladium case. Insert the new strap by aligning the holes with the pin diameter (approximately 1.5mm), then reposition the pin ensuring it clicks securely into both lugs. Avoid impacts that might damage the precious metal.

Yes, any strap with a 20mm lug width is mechanically compatible. However, we recommend selecting straps from specialised artisans who understand the design constraints of luxury watches: the finish quality, stitch density, and material durability must reflect the standard of the palladium case and tourbillon movement.

A high-quality leather strap (vegetable-tanned alligator or Italian calf) lasts between 3 and 5 years with daily wear, depending on ambient humidity and frequency of water exposure. Vegetable tanning develops a natural patina that enhances aesthetics over time; however, the strap should be replaced when fibres begin to fail around the stitching. A 44mm palladium watch deserves regular strap maintenance.
