Strap for Presence 34.5 Automatic Yellow Roman Bracelet

The Longines Presence L4.721.2.11.8 features 18 mm lugs, meaning the strap must have an 18 mm inner distance between the keepers to fit correctly on the case. This measurement is critical and tolerates minimal deviation, so any strap you purchase must be specifically designated as 18 mm compatible.

For the Presence L4.721.2.11.8, we recommend an alligator strap finished with vegetable tanning in dark brown or tobacco. This choice enhances the minimalist aesthetic of the watch and creates elegant contrast with the white dial. Alternatively, smooth calf leather (box calf) offers chromatic versatility and superior dust resistance, ideal for daily wear.

Strap replacement requires a spring bar tool with a forked tip. Position the tool's fork under the elastic pin from the side opposite the spring, apply gentle pressure to release the pin, then remove the old strap. Slide the new strap's keepers onto the pins, ensuring the pins lock firmly into their seats.

Yes, the Presence L4.721.2.11.8 is fully compatible with artisanal aftermarket straps provided they feature 18 mm lug width. MilanoStraps offers customisable straps in various materials (alligator, calf, shell cordovan) with choice of colour, thickness, and stitch thread, ensuring a bespoke result.

A high-quality artisanal leather strap, if worn moderately (5–6 days per week), typically lasts 18–24 months before replacement is necessary. Wear concentrates at the closure area. MilanoStraps guarantees 18 months on atelier-made straps, and vegetable-tanned material develops a patina that enhances its appearance over time.
