Strap for Flagship 35.6 Automatic Pink Gold

The lug width of the Longines Flagship L4.774.8.22.2 is 18 mm. This measurement represents the internal distance between the two attachment points where the strap is inserted. It is a classic dimension characteristic of elegant models in the Genevan watchmaking tradition, distinct from the larger standards (20-22 mm) found on sports chronographs.

For the Flagship in 18k rose gold, American alligator represents the most coherent choice: its regular grain and refined texture reflect the minimalist elegance of the watch. Valid alternatives include vegetable-tanned calf for natural softness, shell cordovan for durability and patina development, or a structured rubber for a contemporary approach.

Strap replacement is accomplished using the spring bars located on the sides of the case. With a dedicated spring bar tool, compress the spring to extract the pin from the upper attachment, slide out the old strap, and insert the new one by aligning it with both attachment points. The operation requires care to avoid scratching the rose gold case.

Yes, any strap with an 18 mm lug width is fully compatible. At milanostraps.it you will find a selection of artisanal straps in alligator, calf, cordovan and rubber, all manufactured or customisable at 18 mm. The Casati Milano atelier also offers the possibility of completely bespoke straps with custom finishing.

Durability depends on material and usage. A quality alligator or calf leather, with appropriate vegetable tanning, typically lasts 3-5 years with moderate daily use. Shell cordovan can exceed 7-8 years due to its inherent strength. Factors such as exposure to perspiration, water and sunlight affect ageing. The Casati Milano warranty covers 18 months from delivery.
