Strap for Presence 34.5 Automatic Yellow Stick

The lug width of the Longines Presence L4.721.2.18.2 is 18 millimetres. This measurement is determined by positioning a calliper between the two internal lug pins that secure the strap to the case. An 18 mm lug width ensures balanced proportions on a 34.50 mm diameter watch and significantly simplifies the search for compatible aftermarket straps.

For the Presence L4.721.2.18.2, we recommend straps in natural alligator (bordeaux, black, chocolate brown), vegetable-tanned calf leather for authentic patina development, or shell cordovan for a more formal and durable character. The brushed stainless steel case is best expressed with leathers that naturally patina over time, emphasising the timepiece's classical essence. For a contemporary alternative, fine-grained rubber offers practicality and versatility.

Strap replacement requires a spring bar tool or small flathead screwdriver. Position the watch with the lug facing upwards, insert the tool into the spring bar slot and lift gently, then remove the pin. Repeat on the opposite side. To install the new strap, reinsert the spring bars into the appropriate holes, ensuring they are perfectly seated. If you prefer to avoid any risk, professional watchmakers can perform the strap change in minutes.

Yes, any strap with an 18 mm lug width is compatible with the Longines Presence L4.721.2.18.2, provided the strap's spring bars fit the case diameter properly. We recommend always verifying the seller's specifications and opting for manufacturers who guarantee compatibility with classic Longines watches. Bespoke artisan straps offer the opportunity to choose leather type, colour, buckle and stitching according to your personal preferences.

Durability depends on leather quality and intensity of use. A high-quality alligator or vegetable-tanned calf strap typically lasts 5-7 years with standard maintenance (regular cleaning and water protection). Shell cordovan is even more durable, often exceeding 10 years. Leather deteriorates faster if exposed to excessive moisture, unwiped perspiration, or repeated flexing. Active wrist wear can reduce lifespan by 2-3 years; occasional use can extend it considerably.
