Strap for Tangente 38 Datum Lemonbiscuit

The lug width of the Tangente 179.S10 is 18mm. This measurement represents the distance between the two lugs (pins) that connect the case to the strap passants. It is important not to confuse this dimension with the total width of the strap at the wrist, which depends on the case geometry and passant construction. To verify the correct measurement, use a digital calliper or ruler, positioning it perpendicularly between the two lugs.

The Tangente 179.S10 responds magnificently to high-quality alligator straps, particularly in natural tones such as cognac, miel brown, or glossy black. The geometric pattern of alligator scales amplifies the minimalist language of the case. Alternatively, vegetable-tanned calf leather with natural ageing represents a sophisticated choice for those seeking progressive patina development. For more casual contexts, certified canvas NATO straps maintain Bauhaus aesthetics without compromise. Natural or synthetic rubber remains ideal for humid or sporting environments.

To change the strap, first obtain a spring bar tool (lug pin remover) designed for the purpose. Position the Tangente 179.S10 on a stable surface and access the lateral lugs using the extraction tool: gentle pressure inward on the lug pin releases the internal spring, allowing pin extraction. Once removed, the strap slides free. For installing the new strap (always 18mm width), insert the pin through the passant holes, then reinsert the spring using the tool. Verify that the pin is fully seated on both sides. Inspect the case for scratches during the procedure.

Yes, the use of aftermarket straps is entirely compatible with the Tangente 179.S10, provided they respect the 18mm lug width and are manufactured with equivalent or superior materials. We recommend consulting specialised suppliers such as Milano Straps, which guarantee straps in vegetable-tanned leather, certified alligator, premium NATO, and natural rubber. The use of poor-quality straps, industrially produced without proper quality control, may compromise the minimalist aesthetics of the watch and accelerate case wear.

The lifespan of a leather strap depends on frequency of wear, environmental conditions, and the quality of tanning. A high-quality alligator or vegetable-tanned calf strap, worn daily on a Tangente 179.S10, maintains structural functionality for 3–5 years. The leather develops natural patina and aged texture, enriching aesthetic character. Humidity, perspiration, and sunlight exposure accelerate ageing: regular maintenance (cleaning with soft cloth, occasional application of specialist balm) extends useful life. Beyond 5 years, the strap begins to show structural failure at stress points, making replacement advisable for safety reasons.
