Strap for Flagship 26 Automatic Diamond Bezel MOP

The Longines Flagship L4.274.0.87.6 features a 12mm lug width. This measurement is specific to the model and reflects the proportionate design of the 26mm case. The lug width is not interchangeable with other sizes and is essential to maintain the aesthetic balance of the timepiece.

For the Flagship L4.274.0.87.6, we recommend a fine-grain alligator in cognac or off-white tones, which emphasises the elegant and timeless nature of the watch. Alternatively, shell cordovan develops an extraordinary patina over time, whilst vegetable-tanned calf leather offers daily versatility. For a sporty approach, fine-weave NATO remains a sober and versatile solution.

Strap changing requires the use of a spring bar remover or similar tool to gently push the spring bar inwards, releasing the strap from the case lugs. Position the new strap by aligning the holes with the lugs, then snap the spring bar in by inserting the strap into the second hole. Work with precision to avoid scratching the stainless steel case.

Yes, any strap with a 12mm lug width is compatible with the Flagship L4.274.0.87.6. It is essential to verify the correct lug width before purchase. Artisanal leather or fabric straps, customisable in every detail, guarantee superior craftsmanship and adapt perfectly to the proportions of the model.

A quality leather strap (alligatore, shell cordovan, vegetable-tanned calf) typically lasts 3–5 years of daily wear, developing a characteristic patina over time that increases aesthetic value. Longevity depends on the type of tanning, frequency of use, and proper maintenance. Noble materials such as shell cordovan or alligator tend to last longer, especially with moderate patination.
