Strap for Presence 40 Small Seconds Stainless Steel / White - Roman

The Longines Presence L4.905.4.11.2 features a lug width of 20 millimetres. This is the standard distance between the two metal lugs on the case where the strap attaches. Correct measurement is critical: use a digital calliper perpendicular to the dial, measuring the inner width of both lug housings. Only straps with precisely 20 mm width will fit without anomalous play.

For the Presence L4.905.4.11.2, we recommend Nile alligator in dark brown or cognac tones, which respects the brushed steel case aesthetic. Vegetable-tanned calf is a valid alternative for those preferring finer grain and natural ageing. Shell cordovan suits only if you accept initial stiffness and intense lustre. Avoid sports materials (NATO, rubber) as these undermine the model's elegant proportions.

Strap replacement requires minimal tools: remove the crown protection cap (if fitted), then use a spring bar tool to gently compress the internal spring, lifting the old strap away. Repeat on both sides. To install the new 20 mm strap, align the holes with the lugs and insert gently until the spring snaps into place. Verify secure attachment on both sides before wearing.

Yes, any strap with precisely 20 mm lug width is compatible. Milanostraps.it offers a selection of artisanal 20 mm straps customisable in material, colour, length, initials and stitch type. Compatibility is guaranteed by correct lug width measurement alone: no brand restriction applies, only physical dimension matters.

An artisanal leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years with daily wear, provided routine maintenance is observed: avoid prolonged immersion, dry promptly after perspiration contact, condition with natural wax every 6–8 months. Leather ages visibly (patina, creases), and this evolution is integral to character. Atelier Casati Milano provides 18-month warranty on bespoke straps, covering manufacturing defects.
