Strap for Super Antarctic 3.6.9. Brown - White Luminous / Stainless Steel / Beads of Rice

The lug width of the 32040A04 is 20 millimetres. This measurement is taken by inserting a calliper between the two lugs of the case, from the inner edge to the inner edge. It is essential to respect this dimension to ensure compatibility with quality aftermarket straps.

The best strap depends on intended use and aesthetic preference. For formal elegance, we recommend alligator or vegetable-tanned calf leather; for daily versatility, a NATO strap in heavy cotton or robust calf; for humid environments or sports activities, rectangular Tropic rubber. All these materials emphasise the functional nature of the instrument whilst maintaining proportional balance with the 38mm case.

Obtain the correct tools: a spring bar tool with sharp tips and a flat work surface. Position the watch securely, supporting the case. Gently insert the spring bar tool into the lug slot, applying upward pressure to extract the retaining bar. Once removed, slide the old strap out and insert the new one, securing it with the bar. The procedure requires patience to avoid scratching the steel.

Any strap equipped with a standard 20-millimetre lug width is compatible, provided it is manufactured to precise tolerances. We advise against low-quality generic straps, which compromise the aesthetics and functionality of the instrument. Prefer specialised craftsmen who understand the proportional requirements of a 38mm watch and guarantee noble materials with accurate finishing.

A quality leather strap—alligator, vegetable-tanned calf—lasts on average 3–5 years with moderate daily use, up to 7–8 years with seasonal alternation. Lifespan depends on exposure to moisture, direct sunlight, perspiration and the type of tanning. Vegetable-tanned leather ages nobly, developing natural patina. Regular maintenance—gentle cleaning, post-moisture drying—significantly extends longevity.
