Frequently asked questions
What is the lug width of the Longines Flagship L4.774.4.27.2?
The lug width is 18 mm. This specific measurement is characteristic of the Flagship 35.60 mm case and requires custom-made straps, as commercial standards (18.5 mm, 20 mm, 22 mm) are not compatible. To verify compatibility, measure the distance between the horizontal pins at the case ends.
Which strap material is most suitable for the Flagship L4.774.4.27.2?
Alligator represents the premium choice, featuring fine grain and patina that evolves over time. For robust everyday wear, box calf offers discretion and durability. Vulcanised rubber is ideal for a versatile and active style. Shell cordovan is reserved for collectors seeking a strap with marked patina and intense chromatic depth.
How do you change the strap on the Longines Flagship L4.774.4.27.2?
Strap replacement is performed by removing the spring bars that connect the strap to the case. Use a spring bar tool to gently compress the internal spring and extract the pin. Insert the new strap by aligning the lugs with the case pins and push the pin until it clicks into place. Verify that the strap is symmetrically aligned before wearing the watch.
Are aftermarket straps available that are compatible with the Longines Flagship L4.774.4.27.2?
Yes, 18 mm straps compatible with the Flagship are available online, ready for shipment and customisable in measurements, initials and thread colour. For a bespoke experience, the Casati Milano atelier crafts custom straps with personal hide selection and 18-month warranty.
How long does a leather strap last on the Flagship L4.774.4.27.2?
Durability depends on material and usage patterns. Alligator and shell cordovan, if properly maintained, last 4–6 years of regular wear. Box calf requires moderate maintenance (hydration with specific creams) and lasts 3–5 years. Vulcanised rubber, being more resistant to wear, can last 5–7 years. Avoid prolonged moisture exposure and store the strap away from direct heat sources.
