Frequently asked questions

What is the lug width of the Longines Presence L4.804.2.11.7?

The lug width of the Longines Presence L4.804.2.11.7 is 18 mm. This measurement is essential for selecting a compatible strap: it represents the distance between the two lateral lugs of the case. An 18 mm strap fits perfectly without play or excessive tension, ensuring comfort and correct aesthetics.

What is the best strap for the Longines Presence L4.804.2.11.7?

The ideal strap depends on usage and personal preference. For formal elegance, we recommend alligator mississippiensis or shell cordovan in dark tones—both amplify the minimalist character of the Presence. For daily practicality, vegetable-tanned calf leather offers durability and visible patina development. Bespoke straps from Casati Milano allow full customisation: choice of leather, colour, thickness, and closure type (classic buckle or deployante).

How do I change the strap on the Longines Presence L4.804.2.11.7?

Strap replacement involves removing the spring bars—small lateral pins holding the strap. You will need a spring bar tool to compress the internal spring mechanism, releasing the old strap. Once removed, insert the new strap and reposition the spring bars until fully secured. This is straightforward for experienced users; alternatively, entrust the operation to Casati Milano for maximum precision.

Can I use a third-party compatible strap with the Longines Presence L4.804.2.11.7?

Yes, any strap with 18 mm lug width is mechanically compatible. However, we recommend selecting quality certified straps: artisanal makers like Casati Milano guarantee noble leathers, French double-stitching, and construction that respects the refined aesthetic of the Presence. Online straps from milanostraps.it offer extensive material and personalisation choices, all validated for 18 mm lugs.

What is the lifespan of a leather strap for the Longines Presence L4.804.2.11.7?

Lifespan depends on material and usage patterns. A high-quality shell cordovan strap can last 5–7 years with daily wear, thanks to its superior fibre density. Vegetable-tanned calf typically lasts 3–4 years; alligator mississippiensis, 4–5 years. Exposure to moisture, heat, and abrasion accelerates wear. Casati Milano warrants 18 months on bespoke straps; maintenance with specialised creams (avoid hot water and aggressive detergents) significantly extends service life.
