Frequently asked questions
What is the lug width of the Longines Master Collection L2.128.8.87.3?
The lug width of the Longines Master Collection L2.128.8.87.3 is 13mm. This measurement is relatively uncommon in the watch market and reflects the miniature proportions of the 25.50mm case. The <a href="/pages/termine-glossario/misura-ansa">lug width</a> is measured from the centre of one lug to the centre of the other and determines strap compatibility. Do not confuse this dimension with the overall case length.
What is the best strap for a Longines Master Collection in rose gold?
For a rose gold timepiece such as the L2.128.8.87.3, <a href="/pages/termine-glossario/alligatore">alligator</a> leather represents the most natural choice thanks to its fine grain that complements the precious case. Cognac, dark brown, or deep burgundy tones create harmonious colour progression. Alternatively, vegetable-tanned calf leather offers a texture that develops patina over time, or <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> for those seeking more pronounced character and metallic reflections.
How do you change the strap on a Longines Master Collection L2.128.8.87.3?
Strap replacement on the L2.128.8.87.3 is accomplished via the two 13mm lugs that connect case and spring bars. Using a spring bar tool, gently compress the internal spring by pushing downward, then extract the pin from the case. The new strap, with its bar pre-installed, is inserted into the case lugs. The operation requires care to avoid scratching the rose gold case.
Are there aftermarket straps compatible with the Longines Master Collection L2.128.8.87.3?
Yes, artisanal straps in 13mm width are available specifically designed for the L2.128.8.87.3. Online at milanostraps.it you can find several options in alligator, calf, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> and rubber, all customisable in length, initials and stitching thread. The Casati Milano atelier also creates bespoke straps with direct consultation and 18-month warranty.
How long does a leather strap last on a Longines watch?
A quality artisanal leather strap, worn daily with proper maintenance, typically lasts 3–5 years before requiring replacement. Durability depends on usage intensity, leather type (alligator and <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> are more resistant), and environmental conditions. Prolonged sun and humidity exposure accelerates wear. A <a href="/pages/termine-glossario/concia-vegetale">vegetable-tanned</a> calf strap develops patina and character over time, improving aesthetically even as it structurally ages.
