Frequently asked questions

What is the lug width of the Longines Master Collection L2.357.4.72.6?

The lug width is 18 millimetres. This measurement represents the space available between the two lugs of the case, where the strap is inserted. It is essential to measure this dimension accurately before purchase to ensure complete compatibility of the strap with your timepiece.

What is the best strap to pair with the Longines Master Collection L2.357.4.72.6?

The best strap depends on the intended use. For formal occasions, an alligator strap with vegetable tanning in warm brown tones or burgundy shell cordovan maintains the watch's elegance. For versatile daily wear, Taurillon calf leather in brown or linen NATO fabric. Natural FKM rubber suits casual contexts. Your choice should reflect the balance between the austere steel case and the softness of the strap material.

How do you change the strap on a Longines Master Collection L2.357.4.72.6?

Remove the spring bars (lug pins) from the case lugs using a spring bar tool. Gently compress the spring inside the pin and slide it out of the lug. Insert the new strap by positioning the spring bars into the corresponding slots and verify that the attachment is secure. For custom straps, Casati Milano provides detailed instructions and mounting support.

Is an aftermarket strap compatible with the Longines Master Collection L2.357.4.72.6?

Yes, provided it conforms to the 18 millimetre lug width. Aftermarket straps of artisanal quality, such as those available on milanostraps.it, are specifically dimensioned for this width. The lug depth is moderate (approximately 5-6 millimetres), so the strap must fit precisely without lateral play. We recommend artisanal straps that guarantee precise tolerances and durability over time.

How long does a leather strap last on the Longines Master Collection L2.357.4.72.6?

The lifespan of a leather strap depends on the tanning method and frequency of use. An alligator or shell cordovan strap with vegetable tanning typically lasts 3-5 years of regular wear, developing an appreciable patina. Taurillon calf leather has a comparable lifespan. Casati Milano straps come with an 18-month guarantee and can be serviced or replaced over time. Exposure to moisture, perspiration and direct sunlight accelerates leather ageing.
