Tangente 101.S16— lug 18mm

The lug width (misura ansa) of the Tangente 101.S16 is precisely 18 millimetres. This measurement is the critical parameter for selecting a compatible strap. To verify, position the watch on your wrist and measure the distance between the centres of the lugs (the pins holding the strap): you will find exactly 18 mm. There is no tolerance—straps of 16 mm or 20 mm will not fit correctly.

The optimal strap depends on your intended use and aesthetic preference. For formal elegance, we recommend alligator with vegetable tanning in cognac, honey, or black tones, which develops a natural patina over time. For raw artisanal robustness, Tuscan calf leather in deep brown is uncompromising. For versatile multi-context wear, a grey-slate NATO canvas or black FKM rubber offers adaptability. The material should have appropriate thickness and restrained texture that does not visually compete with the Tangente's white dial.

The procedure is straightforward. Locate the spring bars (the small metal pins at the lug shoulders). Using a spring bar tool or small lever, press the pin inward and the strap releases. Insert the new 18 mm strap, aligning the holes, then push the pin until it clicks shut. The operation requires care to avoid scratching the case. If you prefer professional assistance, Casati Milano offers strap changes by appointment in Milan.

Lifespan depends on material and usage frequency. Quality alligator or vegetable-tanned calf leather typically lasts 5–8 years with moderate wear (3–4 days weekly). With natural aging, it develops patina and character. Daily wear may reduce this to 3–4 years before signs of stress appear (cracking, loosening). FKM rubber has comparable longevity. Shell cordovan, being denser, can last 10+ years. Maintenance is essential: keep the strap dry, avoid immersion, and apply protective balm every 6–12 months. When a strap eventually fails, it is not a tragedy—it is an opportunity to explore a new colour or material.
