Strap for Presence 34.5 Automatic Small Seconds

The lug width is 18 mm. This measurement is specific to the Presence model and does not correspond to more common standards (19, 20 mm). To verify strap compatibility, check that the lugs insert into the case slots without lateral play and that the strap does not protrude beyond the case profile.

Given the elegant proportions of the Presence (34.50 mm), vegetable-tanned alligator is the ideal formal choice: it ages with uniform patina and maintains sober aesthetics. Vegetable-tanned calf leather (chromexcel) is a robust and practical alternative. Avoid rubber and sports materials, which would visually burden the thin wrist. NATO cotton is appropriate only for casual summer contexts.

Use a spring bar tool to compress the internal spring of each lug. Insert the tool into the lateral slot of the lug, compress the spring inward, and slide the lug out of the case slot. Repeat for the opposite lug. To install a new strap, align the lugs with the case guides and press until you hear a click. The procedure takes just over a minute.

Yes, provided the strap has 18 mm lugs and is constructed with quality comparable to Longines manufacturing standards. A high-quality artisanal alligator or calf strap often exceeds aesthetic expectations compared to the original Longines strap. Ensure that the buckle or deployant clasp is brushed steel to harmonise with the case.

Durability depends on material and usage. Vegetable-tanned alligator lasts 18–36 months with moderate daily wear. Vegetable-tanned calf (chromexcel) resists 12–24 months. Shell cordovan can reach 40–50 months. Patina develops naturally, and the strap ages rather than failing suddenly. Minimal maintenance (cleaning with a soft cloth, protection from direct rain) extends service life. Casati Milano offers an 18-month warranty and discounted replacement services.
