Strap for Flagship 25 Quartz Stainless Steel Silver

The lug width of the Longines Flagship L4.216.4.72.6 is 13mm. This measurement is specific to the refined feminine models within the Flagship collection and is crucial for selecting a compatible strap. To verify correctly, remove the original strap and measure the external distance between the case lugs, or measure internally the space where the strap fits.

The best strap depends on usage and personal preference. Vegetable-tanned alligator is the most noble choice, developing a natural patina over time. Shell cordovan is ideal for those seeking rich and profound ageing of the material. Premium calf leather offers softness and modernity, perfect for daily wear. Structured rubber combines elegance and functionality for dynamic contexts. We recommend choosing the material based on your dial version and personal style.

To change the strap, use a dedicated tool (spring bar tool) to extract the metal terminals (spring bars) that secure the strap to the case lugs. Position the tool on the small groove of the spring bar, gently pushing inward to release the strap. Once the original strap is removed, insert the new strap ensuring that the spring bars fit perfectly into the 13mm lugs. Verify that the strap is securely fastened before wearing the watch.

Yes, quality aftermarket straps are fully compatible, provided they respect the 13mm lug width specification. Many standard straps are designed for 16mm, 18mm, or 20mm lugs, so it is essential to verify that the measurement is exactly 13mm. Custom-made straps from specialised ateliers guarantee a perfect fit and personalised solutions in premium leather, colour, and finish.

The lifespan of a leather strap depends on material quality, frequency of use, and care. A premium-quality alligator or shell cordovan strap, with moderate use (4-5 days per week), typically lasts 5-8 years. Premium calf usually resists for 3-5 years. Rotating between multiple straps significantly extends the life of each, as the leather has time to rest and dry. Regular cleaning with a soft cloth and occasional hydration with appropriate treatments preserve elasticity and aesthetics over time.
