Strap for Presence 33.5 Quartz Yellow Gold / White

The lug width of the Longines Presence L4.743.6.12.2 is 18 mm. This measurement, engraved inside the case between the lugs, determines the compatibility of any aftermarket strap. It is essential to verify this dimension before ordering a replacement strap, as an incompatible lug width will not fit securely and may damage the watch.

For a yellow gold 18-carat Presence, alligator is the natural choice: its geometric texture and the patina that develops over time create perfect dialogue with the metal. Excellent alternatives include European calfskin in dark brown tones, or vegetable-tanned leather for those prioritising sustainability and character. Avoid inferior-quality straps that could diminish the watch's elegance.

The strap is removed by unscrewing the spring bars that connect the lugs to the case. Position the watch on a protective support, then use a spring bar tool to apply gentle pressure on the small lateral pins of the bars, allowing them to disengage from the lug holes. Align the new strap's holes with the spring bar and reseat the bar into position. If you lack experience, entrust the task to a professional to avoid damaging the case.

Yes, the Presence is fully compatible with 18 mm aftermarket straps. Ensure that the strap is equipped with spring bars of the correct length (typically 18 mm for this lug width) and that the buckle or deployant clasp is proportioned to the watch's modest case diameter (33 mm). Avoid excessively thick straps that would appear visually oversized relative to the watch.

A high-quality alligator or calfskin strap typically lasts 3–5 years with daily wear, with variation dependent on climate and humidity. Vegetable-tanned leather tends to last slightly less (2–4 years) but develops a more distinctive patina. Deterioration typically begins in zones of greatest flexion (beneath the buckle and at the lug transition). Regular maintenance with leather wax and rotating use with other straps significantly extends the life of the piece.
