Frequently asked questions
What is the lug width of the Longines Master Collection L2.628.5.59.7?
The Longines Master Collection L2.628.5.59.7 features a lug width (ansa measurement) of 20 mm. This dimension represents the distance between the inner holes of the fixed lugs (anse). It is essential to verify this parameter before purchasing a strap, as it determines the compatibility between the case and the strap. A measurement error results in a strap that either sits too loosely or fails to fit into the lug holes properly.
Which strap is recommended for the Master Collection L2.628.5.59.7?
For the Master Collection L2.628.5.59.7, three categories of straps are recommended. Alligator leather with vegetable tanning in dark colours (brown, dark tan, black) represents the most elegant and traditional choice, consistent with the case's aesthetic philosophy. Fine-grained calf leather (such as Chamonix or Fjord) offers softness and understatement, ideal for those preferring neutral tones. Canvas NATO straps, particularly in navy blue, allow rapid changeover and versatility in informal contexts whilst maintaining design formality. Rubber or silicone straps are not advisable, as they conflict with the model's classical nature.
How do you change the strap of the Longines Master Collection L2.628.5.59.7?
Changing the strap of the L2.628.5.59.7 requires extraction of the spring bars (pins) that secure the strap within the lugs. The standard procedure is: 1) Obtain a spring bar tool (a purpose-designed lever instrument). 2) Position the lever under the pin from one side, applying gentle lateral pressure to compress the internal spring. 3) Extract the pin. 4) Repeat from the opposite side. 5) Align the new strap's holes with the pins and press until the safety click is felt. We recommend entrusting this operation to a professional if you lack experience, to avoid scratching the case.
Is an aftermarket strap compatible with the Longines Master Collection L2.628.5.59.7?
Yes, any strap with a 20 mm lug width is compatible with the Master Collection L2.628.5.59.7, regardless of brand. Compatibility depends solely on the lug measurement (20 mm) and the total strap length (typically between 115 and 140 mm for this watch category). A quality aftermarket strap, crafted from premium leather with appropriate finishing, causes no damage to the case and allows greater personalisation compared to Longines original straps, usually at lower cost.
What is the lifespan of a leather strap on the Longines Master Collection L2.628.5.59.7?
The lifespan of a leather strap depends on construction quality, the tanning method used, frequency of wear and maintenance practices. An alligator strap with vegetable tanning, if worn daily and subjected to regular maintenance (dusting, occasional treatment with appropriate balm), easily achieves 3–5 years of functional life. Calf leather, less resistant to abrasion, typically requires replacement more frequently (2–3 years). Factors accelerating wear include prolonged sun exposure, salty environments, contact with greasy substances and lack of rotation between multiple straps. Periodic replacement is not damage but intelligent conservation: straps are consumable parts, like shoe heel taps.
