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

The Nivada Grenchen Super Antarctic 32040A20 features a 20mm lug width, compatible with standard strap lugs for Swiss sports watches. This dimension is proportioned to the 38mm case and ensures balanced aesthetics on average wrists. To verify compatibility, position a ruler perpendicular to the lugs and measure the internal distance between the two case shoulders—it must equal exactly 20mm.

The ideal strap depends on intended use. For sophisticated elegance, American alligator in vegetable tanning with warm tan colour offers refined aesthetics and longevity. For daily robustness, vegetable-tanned calf leather in black or deep brown ensures minimal maintenance and natural patina development. For marine environments or extreme climates, woven NATO fabric or Tropic rubber strap provides UV and temperature resistance without compromise. Atelier Casati Milano customizes every option in 20mm width according to your specifications.

The Super Antarctic 32040A20 utilizes fixed integrated lugs. Remove the worn strap by sliding it out from the lugs—no special tools required. Insert the new 20mm strap into the lug slots, ensuring correct corner alignment. If the strap features a deployante clasp, verify that the buckle faces downward correctly. Casati Milano supplies straps pre-finished to professional standards, guaranteeing straightforward installation.

Yes, the 32040A20 accepts aftermarket straps with exactly 20mm lug width. This dimension is standard, allowing broad choice among specialized suppliers. Always verify that the strap is manufactured for 20mm lugs and that the thickness of the lug slots matches the case lugs (approximately 1.6-2.0mm). Atelier Casati Milano guarantees technical compatibility on all 20mm straps produced.

Leather strap longevity depends on tanning method and usage. Vegetable-tanned calf leather, properly maintained, lasts 3-5 years with daily wear. Vegetable-tanned alligator reaches 5-7 years if protected from excessive moisture. Natural patina increases character over time. Casati Milano recommends periodic maintenance with neutral balm and storage in dry conditions. Signs of wear such as creasing or buckle failure indicate replacement timing.
