Strap for Presence 40 Automatic Stainless Steel / Blue

The lug width of the Longines Presence L4.922.4.92.2 is 20mm. This measurement refers to the internal distance between the spring bar attachments on the case sides. Any compatible strap must be exactly 20mm wide to ensure a precise fit without play or excessive tension.

The optimal strap choice depends on your use case. For formal occasions, black alligator with stainless steel deployante is unmatched. For daily elegant wear, vegetable-tanned calf in burgundy develops a warm patina that complements the grey dial beautifully. For humid professional environments, black FKM rubber maintains proportions and practicality without compromise. Atelier Casati Milano personalises each strap to your preference.

To change the strap, obtain a spring bar tool (available online or from jewellers). Place the watch on a soft surface. Locate the spring bar connecting the strap to the case and insert the tool into the small lateral hole, applying gentle pressure to release the spring. Remove the old strap. Insert the new 20mm strap, aligning the holes, and allow the spring to close into the case. If uncertain, consult a professional watchmaker.

Yes, any quality 20mm strap is compatible with the L4.922.4.92.2, provided the spring bars are dimensioned for 20mm. We recommend artisanal leather straps (alligator, calf, shell cordovan) or technical rubber for durability and comfort. Always verify that your supplier confirms the 20mm lug width specification.

A high-quality leather strap—such as alligator or artisanal calf—typically lasts 3 to 5 years with moderate daily use and proper care. Longevity depends on usage frequency, climate (humidity accelerates ageing), sun exposure, and maintenance. Atelier Casati Milano offers 18 months warranty and maintenance services. FKM rubber straps last 5–7 years; well-maintained shell cordovan reaches 8+ years.
