Strap for Avant-Garde Date Lady Black MOP / Strap

The lug width of the 2940.41.40.1357 model is precisely 20 millimetres, measured internally from one lug wall to the other. This specification is standardised across the Contemporary Eterna line and compatible with all 20mm aftermarket straps. Always verify the measurement with a digital calliper before purchasing.

For the Contemporary with a 28mm stainless steel case, we recommend alligator leather or vegetable-tanned calf in brown, cognac, or grey tones. A cotton NATO provides sportive versatility, whilst FKM rubber in black suits rigorous professional environments. Selection depends on intended use and your watch's dial colour.

The 2940.41.40.1357 features standard straight 20mm lugs. Use a spring bar tool to gently push the spring bars downward, releasing the old strap. Insert the new 20mm strap ensuring both spring bars click into position. Do not force: smooth movement indicates correct alignment.

Yes, the 2940.41.40.1357 accepts any quality 20mm strap featuring standard straight lugs. Artisanal milanostraps.it straps in leather, NATO, and rubber are fully compatible. Verify that the spring bars are parallel and internal width is exactly 20mm.

A vegetable-tanned calf or alligator leather strap, with regular maintenance, typically lasts 2-3 years on a 28mm daily-wear watch. Durability depends on humidity, wearing frequency, and sun exposure. An annual service at Casati Milano significantly extends strap life through conditioning and buckle adjustment.
