Strap for Super Antarctic 3.6.9. Brown - Beige Luminous / Stainless Steel / Flat Link

The lug width is 20mm, measured from the inside edge of one lug to the other. This width is specific to this model and corresponds to Swiss manufacturing standards from the 1950s. It is essential to verify that the compatible strap has been constructed for exactly 20mm width, as even minor deviations result in imprecise fit.

The ideal strap depends on your aesthetic intent: vegetable-tanned leather emphasises sober elegance, NATO maintains historical military fidelity, vulcanised rubber guarantees hydrophobic performance. Genuine alligator strap represents the highest level of sophistication. We recommend consulting the 20mm strap section at milanostraps.it to view available options.

The strap is replaced by removing the spring bars that attach the strap to the case lugs. Use a dedicated spring bar tool, inserting it gently into the small lateral hole and extracting the pin outward. Install the new strap by reversing the process: position the spring bar on the upper and lower lug holes, then press until you feel the securing click. Proceed carefully to avoid scratching the case.

Yes, provided the lug width is exactly 20mm. High-quality bespoke straps offer far greater freedom in material and finish selection than original straps. Ensure the strap has been constructed specifically for this width and uses spring bars of quality appropriate to the watch's value.

The lifespan of a vegetable-tanned leather strap depends on usage intensity and climate. Under normal conditions (daily wear, temperate climate), expect 3-5 years before the strap begins showing significant wear. Humid climates or chemically aggressive environments reduce this duration. Vulcanised rubber, conversely, resists for 5-7 years with less aesthetic degradation, though tactile resilience declines progressively.
