Strap for Presence 38.5 Quartz Stainless Steel / White

The lug width of the Longines Presence L4.790.4.12.2 is 30mm, an uncommon specification requiring specifically sized straps. You can measure it using a digital calliper positioned between the two lug terminals, or by verifying the width of the original strap. This measurement allows no tolerance: a 28mm or 32mm strap will not fit properly.

For the Presence, we recommend alligator leather in black, dark blue, or cognac brown: its natural grain elevates the watch's understated elegance. Calf leather is an excellent alternative, softer and more adaptable, whilst shell cordovan suits those seeking pronounced patina development. For informal occasions, a cotton NATO strap also works admirably, maintaining aesthetic coherence.

Changing the strap on the L4.790.4.12.2 requires a dedicated tool (spring bar removal tool) or professional assistance. Place the watch face-down on a soft cloth, locate the lug pins on the case back, insert the removal tool into the hole, and gently push the pin outward. Once extracted, the strap disengages. Install the new strap by aligning its holes with the pins and press until you hear a click.

Yes, Milano Straps offers a comprehensive range of 30mm aftermarket straps, customisable in leather type (alligator, calf, shell cordovan, vegetable-tanned) and finishing details (thread colour, initials). All straps are tested for dimensional compatibility. Alternatively, Casati Milano creates bespoke straps by appointment with personalised measurements and an 18-month guarantee.

Durability depends on leather quality and usage patterns. Premium alligator can exceed 5-7 years with routine maintenance (periodic cleaning, avoiding direct sunlight). Calf leather typically lasts 3-5 years, shell cordovan 4-6 years. Vegetable-tanned leather develops patina quickly and requires regular conditioning with wax, but exceeds 7 years if properly maintained. Milano Straps straps carry an 18-month guarantee under all conditions of use.
