Frequently asked questions
What is the lug width of the Longines Master Collection L2.628.4.51.6?
The lug width of the Longines Master Collection L2.628.4.51.6 is 20 mm. This is the net distance between the two lugs (the attachment points of the strap to the case). It is a specific standard for this model, not universal: ensure you measure correctly with a digital calliper before purchasing a compatible strap.
Which strap is best suited for the Longines Master Collection L2.628.4.51.6?
For the Master Collection L2.628.4.51.6, we recommend alligator in medium brown or calf leather with vegetable tanning. These materials respect the minimalist aesthetic of the watch and age with dignity, developing natural patina over time. If you prefer a sporty style, black FKM rubber or a Cordura canvas strap with titanium buckle are valid alternatives.
How do I change the strap on the Longines Master Collection L2.628.4.51.6?
The Longines Master Collection L2.628.4.51.6 uses hinged lugs. To remove the strap: position the watch on a support rod, locate the small release button on the underside of each lug, press gently with a flat tool (a spring bar tool is ideal), and the strap will detach. Inserting the new strap follows the reverse procedure. If you feel uncertain, entrust the task to a professional watchmaker.
Can I use an aftermarket compatible strap on my Longines?
Yes, any strap with a 20 mm lug width is compatible with the Longines Master Collection L2.628.4.51.6. Important: verify the exact width (20 mm measured between inner shoulders), the strap thickness (must slide smoothly through the passant without forcing), and construction quality. Milano Straps artisanal straps guarantee superior finishing standards and certified materials.
How long does a leather strap last on the Longines Master Collection L2.628.4.51.6?
Durability depends on the material and usage. Alligator or vegetable-tanned calf lasts 3-5 years in daily wear, requiring minimal maintenance (occasional cleaning, drying after sweat exposure). Shell cordovan can last 8-10 years whilst developing an increasingly beautiful patina. FKM rubber has a longevity of 5-7 years with gradual degradation. Always store the strap in a dry place, away from direct heat sources.
