Made to Measure

The strap for this watch is made to measure

On the Longines Record the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

How do I change the strap on my Longines Record L2.320.4.57.6?

The Longines Record L2.320.4.57.6 uses the traditional removable spring bar system. Remove the old strap by gently pushing the spring bar to one side with an appropriate tool (spring bar removal tool), extract the strap, and insert the new one by aligning the terminal holes with the bars. Ensure the spring bar is firmly positioned on both sides. If unsure, entrust the strap change to a professional service to avoid case damage.

How long does a leather strap last on the Longines Record L2.320.4.57.6?

The lifespan of a leather strap depends on usage, climatic conditions, and material. A quality alligator or shell cordovan strap, worn regularly on a compact watch like the Record, maintains structural integrity for 3-5 years. Leather develops natural patina and minor creasing is normal. Humidity and sun exposure accelerate ageing. To extend lifespan, avoid prolonged immersion and store in a dry environment. Artisanal vegetable-tanned straps, renewed every 2-3 years, guarantee optimal performance over time.
