Frequently asked questions

What is the lug width of the Longines Equestrian L6.138.0.71.2?

The lug width of the Longines Equestrian L6.138.0.71.2 is 16mm. This measurement represents the distance between the case lugs and is essential for selecting compatible straps. Always verify this specification before purchasing an aftermarket strap, as an incorrect width would result in excessive play or mounting impossibility.

What strap is most suitable for the Longines Equestrian L6.138.0.71.2?

For the Longines Equestrian L6.138.0.71.2, we recommend straps in alligator with vegetable tanning, which impart formal elegance and develop natural patina over time. Shell cordovan in brown represents an excellent narrative alternative given the connection to the equestrian world. For intense daily use, vegetable-tanned calf leather in neutral tones (cognac, black, stone grey) offers durable versatility.

How do you change the strap on the Longines Equestrian L6.138.0.71.2?

The Longines Equestrian L6.138.0.71.2 uses spring bar lugs for strap attachment. Using a dedicated spring bar tool, deactivate the internal spring on the left lug, remove the old strap, insert the new one by aligning the holes with the case lugs, and reactivate the spring. Proceed with care to avoid damaging the case: professional assistance is advisable for the first time.

Is an aftermarket strap compatible with the Longines Equestrian L6.138.0.71.2?

Yes, any strap with a 16mm lug width is compatible with the Longines Equestrian L6.138.0.71.2. Ensure the strap features standard lugs (not proprietary) and that total length is sufficient for your wrist. Artisanal straps from Milano Straps are specifically crafted for this size with noble vegetable-tanned materials.

How long does a leather strap last on the Longines Equestrian L6.138.0.71.2?

The lifespan of a leather strap depends on the tanning method, usage, and care. A strap in alligator or vegetable-tanned calf, if kept dry and protected from excessive moisture, has a lifespan of 5-10 years with daily use. Shell cordovan, given its intrinsic density, can reach even 15 years. Technical rubber straps offer 3-5 years of durability. Casati Milano's 18-month warranty covers manufacturing and stitching defects.
