Strap for Spirit Automatic 42 Blue / Bracelet

The lug width of the Longines Spirit L3.811.4.93.6 is 22mm. This dimension represents the space between the two lugs (spring bar attachment points) on the case and is essential for selecting a compatible strap. To verify it, use a digital calliper positioned on the inner plane of one lug to the other.

For the L3.811.4.93.6, we recommend vegetable-tanned leather in tobacco brown or European calf with matte finish. These materials respect the technical and instrumental identity of the model. For humid environments, a synthetic NATO or vulcanised rubber strap offers practicality without aesthetic compromise.

Remove the watch from your wrist. Position a spring bar tool underneath the lug side and gently push downward to release the internal spring. Remove the old strap and, while keeping the spring open with the tool, insert the new strap ensuring the spring clicks firmly into the holes. Repeat on the other side.

Yes, entirely. Any strap with a 22mm lug width is compatible with the L3.811.4.93.6. Milano Straps' handcrafted straps are manufactured in Italy from certified leather and handmade construction, guaranteeing superior quality and longevity compared to standard OEM alternatives.
