Strap for SportTaucher Stainless Steel / Black / Black Leather

The lug width of the Archimede Sporttaucher UA8974-TS-A4.5 is 20 millimetres. This measurement refers to the distance between the two metal lugs anchoring the strap to the case. A compatible 20 mm strap ensures perfect positioning without visual gaps or mounting instability.

The choice depends on your usage context. For formal elegance, we recommend alligator with vegetable tanning or chrome-tanned calf leather with magnetic deployante. For sport-nautical wear, a NATO fabric strap or hydrophilic rubber strap guarantees security and practicality. The stainless steel satined case pairs excellently with all these materials, allowing personalised aesthetic selection.

The strap is secured via two metal lugs on the case. To remove the strap, use a specialised tool (spring bar tool) to compress the internal spring pin and extract it from the lug side. The process requires care to avoid scratching the case. Once the previous strap is removed, a 20 mm strap inserts easily into the same seat. For those unfamiliar with the procedure, the Casati Milano atelier provides technical consultation and support.

Yes, milanostraps.it offers a specialised selection of compatible straps for the 20 mm lug width. The handcrafted straps are made with premium leathers (alligator, shell cordovan, high-quality calf), hand-stitched, carefully finished, and equipped with reliable deployante clasps. Each strap is designed to respect the case geometry and amplify the timepiece's overall construction quality.

A high-quality leather strap, subjected to moderate daily use, maintains structural integrity for 3–5 years. Straps made with vegetable tanning develop an aged patina that increases aesthetic appeal over time. Factors such as sun exposure, salt sweat, and environmental humidity accelerate wear. Regular maintenance (cleaning and conditioning) significantly extends the useful life of the strap.
