Integrated attachment: measurements, the most common questions, and the way to a made-to-measure strap.

Lug width to be confirmed

On this Longines Record L2.321.5.57.7 the lug width doesn't convince me, and I don't want to give you a number I'm not sure about. Write to me on WhatsApp with the reference or a photo of the watch: I'll check it and tell you myself.

Frequently asked questions

How do you change the strap on the Longines Record L2.321.5.57.7?

Strap replacement requires a spring bar remover tool (small dual-tipped screwdriver) or dedicated extractor. Position the watch face-down on a soft surface. Insert the flat tip of the tool under the spring bar from one side, applying gentle outward pressure until the pin compresses. Remove the old strap and insert the new one by aligning the holes. Repeat on the other side. Verify that the spring bar is perfectly seated to prevent accidental loss.

How long does a leather strap last on the Longines Record L2.321.5.57.7?

Durability depends on material and usage. An alligator or shell cordovan strap, with ordinary care (drying after water exposure, protection from direct heat), maintains structural integrity between 3 and 5 years of daily wear. Vegetable-tanned leather visibly evolves during the first year, developing patina and tonal variations, without losing functionality. A NATO fabric strap lasts over 5 years. The buckle represents the critical point: deployante mechanism wear may require replacement even if leather remains intact. Casati Milano offers 18-month warranty on all custom-made artisanal straps.
