Frequently asked questions

What is the lug width of the Longines Master Collection L2.859.4.78.3?

The lug width of the Longines Master Collection L2.859.4.78.3 is 22 millimetres. This measurement must correspond exactly to your replacement strap. Always verify the lug width with a calliper before purchasing to ensure compatibility and proper fit.

Which strap would you recommend for the Longines Master Collection L2.859.4.78.3?

For the Master Collection L2.859.4.78.3, we recommend alligator straps in dark blue or black for maximum formal elegance, or vegetable-tanned calf in cognac for a warmer aesthetic. For sporty use, a cotton-nylon NATO in grey or vulcanised rubber offers practicality whilst maintaining visual coherence with the stainless steel case and silver dial.

How do I change the strap on a Longines Master Collection L2.859.4.78.3?

Remove the articulation pins that hold the lugs. Use an appropriate tool (pin remover or fine screwdriver) to gently push the pins from the opposite side until they release. Align the new strap with the case lugs and reinsert the pins until fully seated. Never force the process—controlled movement prevents damage to the case.

Is a 22mm strap compatible with other watches besides the Longines L2.859.4.78.3?

A 22mm strap is theoretically compatible with any watch featuring 22mm lugs, regardless of brand. However, the shoulder curve and thickness must match your specific case geometry. Milano Straps straps for the Master Collection are optimised for this reference; always verify complete dimensions before purchase.

How long does a leather strap last on a Longines Master Collection L2.859.4.78.3?

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3–5 years with daily wear, provided proper maintenance: avoid prolonged exposure to water and humidity, protect from direct sunlight, and condition periodically with neutral wax. Milano Straps straps include an 18-month warranty and age beautifully, developing unique patina over time.
