Strap for Flagship 40 Stainless Steel - Yellow Gold / Gilt / Bracelet

The Longines Flagship L4.984.3.32.7 features a 21mm lug width, measured between the inner edges of the spring bars. This dimension is specific to this model and is not compatible with 20mm or 22mm straps. Precise measurement ensures proper fitment and secure attachment.

Material selection depends on intended use. For formal settings, alligator or vegetable-tanned shell cordovan develop a natural patina over time. Fine-grained calf in cognac or chocolate tones offers daily versatility. For resistance and practicality, an FKM rubber strap with canvas inserts provides contemporary functionality without compromising construction quality.

Use a dedicated spring bar removal tool inserted gently into the small slot of each spring bar, pushing outward until disengaged. Repeat on the opposite lug. Once freed, the strap slides away. For installation, align the new strap's lugs with the spring bars and push until fully seated with an audible click.

Longevity varies by material and usage patterns. Fine-grained calf typically lasts 2–3 years with regular maintenance. Vegetable-tanned shell cordovan lasts 4–5 years, developing distinctive patina. Alligator offers similar durability to calf with superior humidity resistance. Regular maintenance—cleaning, periodic conditioning, and post-humidity drying—significantly extends operational life.
