Frequently asked questions

What is the lug width of the Longines Equestrian L6.131.4.57.0?

The lug width of the Longines Equestrian L6.131.4.57.0 is 14mm. This measurement represents the distance between the two lugs on the case where the strap attaches. It is essential to verify this dimension before purchasing an aftermarket strap to ensure complete compatibility.

Which strap is best suited for the Longines Equestrian L6.131.4.57.0?

For this 30mm model, we recommend alligator or vegetable-tanned calf leather for elegant daily wear, or structured rubber for equestrian or humid environments. Dark brown or cognac alligator creates the most elegant visual contrast with the guilloché dial. Your choice depends on intended use and personal maintenance preference.

How do I change the strap on a Longines Equestrian?

Remove the strap using a spring bar tool to compress the internal springs of the lugs. Position the tool in the lateral groove of the pin, apply gentle pressure to lever it out, and extract the pin. Replace the strap by aligning the new pins with the lugs, then reinsert the pins until you feel the locking click. If unfamiliar with the process, Casati Milano atelier offers this service by appointment.

Can I use a quality aftermarket strap on this watch?

Absolutely. A quality artisanal aftermarket strap with the correct 14mm lug width is completely compatible and causes no damage to the watch. It actually offers stylistic freedom and personalisation. Milano Straps offers 14mm straps crafted from selected leather and artisanal finishes that enhance your Longines proportions.

How long does a leather strap last on a Longines Equestrian?

A quality artisanal leather strap with vegetable tanning lasts on average 3-5 years of intensive daily use, up to 7-8 years with seasonal rotation. Durability depends on exposure to perspiration, humidity and storage. Milano Straps straps carry an 18-month warranty and can be regenerated or replaced. Technical rubber lasts considerably longer, up to 10 years.
