Strap for Flagship 38.5 Automatic Stainless Steel / White / Bracelet

The lug width of the Longines Flagship L4.974.4.12.6 is 20 mm. This measurement represents the distance between the lugs of the case and is essential for selecting a compatible strap. You can verify it by measuring directly inside the lugs or consulting the official Longines documentation.

There is no universal choice, but it depends on your style. Black alligator with a silver deployante is ideal for formal occasions; cordovan shell in burgundy or deep brown offers incomparable aesthetic patina; vegetable-tanned calf in dark grey is perfect for those seeking softness and everyday versatility. The stainless steel case of this model pairs well with an extensive range of materials.

The Flagship L4.974.4.12.6 features straight lugs. To change the strap, use a spring bar tool to extract the lug pin, remove the old strap, and insert the new strap by threading the pin through the case lugs. Ensure the pin is secure and the strap is properly aligned with the case.

Any strap with a 20 mm lug width is compatible. Our collection offers handcrafted straps in alligator, shell cordovan, vegetable-tanned calf, NATO, and structured rubber, all customisable in length, initials, and thread colour. Explore our dedicated 20mm strap section to discover available options.

A high-quality artisanal leather strap lasts an average of 3-5 years with moderate daily use, especially with good rotation between straps. Alligator tends to last longer (5-8 years), whilst vegetable-tanned calf may require replacement sooner if frequently exposed to excessive moisture or heat. Regular maintenance (gentle cleaning, dry storage) significantly extends the strap's lifespan.
