Strap for Presence 38.5 Automatic PVD Gold / Champagne / Strap

The lug width of the Longines Presence L4.921.2.42.2 is 20 mm. This dimension is crucial for aftermarket strap selection and is not compatible with 18 mm or 22 mm lugs. It is measured by calculating the distance between the centre of the upper lug hole and the centre of the lower lug hole on the case shoulder.

For the Longines Presence L4.921.2.42.2, we recommend alligator leather with vegetable tanning and fine grain first and foremost, as it highlights the soberness of the brushed stainless steel case. Alternatively, cognac-coloured calf or shell cordovan offer character and durability. Straps must have sufficient thickness to respect the case proportions.

To change the strap, you need to access the case lugs using a dedicated tool (spring bar removal tool). Gently remove the two side spring bars by pushing them laterally and extracting them, then replace the old strap with the new one, ensuring that the bars click firmly into position.

Yes, it is possible to use quality aftermarket straps with a 20 mm lug width. However, we recommend choosing specialised manufacturers that respect both the physical dimensions and the construction standard of the Longines case. A poor-quality strap can compromise both the aesthetics and functionality of the watch.

A quality leather strap, such as alligator or shell cordovan, typically lasts 3-5 years with regular maintenance and rotation with other straps. Durability depends on daily use, climate and the tanning method employed. Vegetable-tanned straps tend to last longer and develop a fascinating patina over time.
