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

The lug width of the Longines Presence L4.821.2.32.2 is 18mm. This dimension is specific to the 34.50mm case and ensures harmonious proportions. To verify it, measure the perpendicular distance between the two case lugs: it should measure exactly 18mm. An incorrectly sized strap will not fit properly or will be unstable.

Alligator in vegetable tanning is the philological choice: the geometric grain enhances the case's sobriety without competing visually. Calf leather, a versatile alternative, allows for fascinating natural patina development and offers tactile softness. Shell cordovan is excellent for extreme durability and colour evolution over time. Rubber or NATO straps are functional but tend to excessively casualise the minimalist elegance of this model.

Strap change requires the use of a spring bar tool (small, flat implement). Position the watch on a stable surface, insert the tool into the slot beneath the lug pin from inside the case, gently lift to release the pin, remove the old strap. Repeat on the other side. To insert the new strap, align the holes with the lugs, reinsert the pins using the tool until you hear a click. Avoid excessive force to prevent case damage.

Yes, with the essential condition that the lug width is 18mm. Quality aftermarket leather or rubber straps do not damage the watch and allow aesthetic versatility. MilanoStraps offers handcrafted 18mm straps in alligator, calf and shell cordovan that are customisable. For superior quality and guaranteed durability, the Casati Milano atelier creates bespoke straps with personal leather selection and 18-month warranty.

A natural leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with regular daily use. Durability depends on the material (shell cordovan lasts up to 7-8 years), frequency of use, environmental humidity and maintenance. Vegetable-tanned leathers age naturally, acquiring fascinating patina. Avoid prolonged contact with water and extreme moisture. A rubber or textile strap lasts 2-3 years. Replacement is simple and affordable: strap change does not require watchmaker services.
