Strap for TEC1

The lug width of this model is 20mm. This measurement is standard for medium to large-sized sports watches and is essential for ensuring secure attachment to the red gold case. To verify your watch's lug width correctly, measure the internal distance between the two spring bars that connect the strap to the case: it must be precisely 20mm.

For this model, we recommend an alligator strap in dark brown, havana, or black tones, as the granular texture of crocodile leather complements the red gold case beautifully. Vegetable-tanned calf leather is a versatile alternative that develops a rich patina over time. For sporty occasions, a cotton oxford NATO maintains the watch's British character. Satin-finished fluoroelastomer rubber offers an elegant transition to smart-casual settings.

To change the strap, position your watch with the lug facing upward. Using a spring bar tool, gently depress the internal lug: the spring bar will retract, allowing you to remove it from the case. Repeat for the other lug. To install a new strap, align the lugs and insert the spring bars into the case slots, ensuring they lock completely.

Yes, you can use quality aftermarket straps provided they are certified for 20mm lug width and crafted from premium materials. Milano Straps' artisanal straps guarantee structural and aesthetic compatibility with your Arnold & Son, offering finishes, thicknesses, and colours customized to your style. Always ensure the spring bars are original or equivalent quality for security.

A leather strap's lifespan depends on usage and care. An artisanal alligator or shell cordovan strap, worn daily with routine maintenance (occasional cleaning with a soft cloth), typically lasts 5-8 years before replacement is needed. Humidity, prolonged sun exposure, and perspiration accelerate ageing. Adopting a second strap for rotation significantly extends longevity. Atelier Casati Milano recommends seasonal rotation for valuable watches.
