Strap for Presence Automatic 34.5mm Stainless Steel / PVD Gold / Champagne / Bracelet

The lug width (ansa width) of the Longines Presence L4.821.2.32.7 is 18mm. This measurement refers to the distance between the two spring bar pins that connect the strap to the case. To verify this precisely, use a digital calliper and measure the internal space between the threaded holes of the case, perpendicular to the dial.

The Presence, with its 34.50mm diameter and 1970s-inspired aesthetic, pairs ideally with leather straps in alligator or vegetable-tanned calf, which enhance the materiality of the stainless steel case. For sportier contexts, choose a NATO strap or FKM rubber option. Recommended colours are burgundy, cognac brown, black, and grey for NATO fabrics. Always select straps with an 18mm lug width.

The strap is changed by removing the spring bars that connect it to the case lugs. Use a dedicated spring bar tool to lift the central portion of the pin and slide it outward. Once both pins are free, the old strap detaches. Insert the new strap by aligning its holes with the case lugs and reinsert the pins until you hear a clear 'click'. This operation requires care to avoid damaging the case.

All artisanal straps made to a lug width of 18mm are compatible. On milanostraps.it you will find a curated selection of ready-made straps in alligator, calf, NATO, and rubber, customisable in length, initials, and stitching thread. For a complete bespoke solution, Casati Milano's atelier creates straps to commission with direct leather selection and an 18-month warranty. Avoid generic 20mm or 22mm straps, which do not fit 18mm lugs.

An artisanal leather strap (alligator, calf, or other quality hides) typically lasts 4–7 years with daily wear, provided it is maintained correctly. Longevity depends on water exposure, perspiration, temperature fluctuations, and conditioning frequency. Alligator straps tend to outlast simple calf thanks to their grain density. To extend strap life, avoid prolonged submersion, apply protective balms every 6 months, and allow leather to breathe during periods of non-use. Casati Milano straps carry an 18-month warranty against manufacturing and material defects.
