Strap for Presence 33 Quartz Stainless Steel

The Longines Presence L4.720.4.12.2 requires watch straps with an 18mm lug width. This measurement is taken between the lateral lugs of the case and is specific to this 33mm model, incompatible with standard 16mm or 20mm widths.

For the Presence L4.720.4.12.2, we recommend alligator in medium brown for classic elegance, vegetable-tanned calf for daily wear, or navy alligator for blue dials. Your choice depends on intended use: formal, business, or casual.

Obtain a spring bar tool (dedicated instrument). Position the tip in the lateral hole of the lug pin, gently lift and release one end of the strap. Repeat on the other side. Insert the new 18mm strap and depress the pin until it clicks into position.

Yes, any artisanal strap with 18mm lug width is compatible. Choose models featuring a stainless steel deployant clasp and quality materials (alligator, shell cordovan, calf). Avoid synthetics and generic straps that fail to honour the case quality.

A quality alligator or calf strap lasts 3–5 years with daily wear, up to 7–8 years with seasonal rotation. Vegetable-tanned leather ages elegantly, developing patina. Longevity depends on climate, humidity, and maintenance—avoid prolonged perspiration exposure.
