Strap for Elegant Collection 34.5 Automatic Stainless Steel / MOP / Bracelet

The lug width of the Longines Elegant L4.809.4.87.6 is 19 mm. This is an exceptionally rare measurement in contemporary watchmaking, inherited from European dress watches of the 1960s. To verify compatibility, measure the internal space between the two metal lugs perpendicular to the movement using a digital calliper: the value must fall between 18.8 and 19.2 mm.

Alligator is the canonically correct choice for this reference: its fine grain and naturally geometric texture evoke the tonic elegance proper to Swiss dress watches. Alternatively, shell cordovan offers a crystalline luminous reflection that is equally compelling, while vegetable-tanned calf introduces a textural roughness that ages dramatically. Natural rubber straps are functionally compatible but visually compress the formal proportions.

The Longines Elegant utilises a fixed lug system. To remove the current strap, you must extract the spring bars (pins) connecting the strap to the metal lugs of the case. Use a spring bar tool (dedicated lever) to compress the small internal hook of each pin and slide it away from the lug. Insert the new strap by aligning the holes to the lugs, reintroduce the pins (ensuring the internal hook faces inward), and verify they are fully seated. If you are inexperienced, manual replacement risks scratching the case: entrust the work to Atelier Casati Milano for professional execution.

Yes, any strap with a 19 mm lug width is technically compatible. However, construction quality and material selection significantly influence final aesthetics. The artisan straps at milanostraps.it are designed specifically for dress watch proportions, guaranteeing aesthetic coherence and superior durability compared to industrial standard straps. Always verify that the spring bar pins (typically 14 mm) are compatible with your lugs before purchase.

The lifespan of a leather strap varies according to material and usage. Alligator and shell cordovan, if properly maintained, retain structural integrity for 5–8 years of intense daily wear; vegetable-tanned calf can reach 4–6 years. Proper maintenance (drying leather after moisture contact, avoiding sharp creases, applying natural wax every 6–12 months) extends useful life significantly. Casati Milano artisan straps carry an 18-month defect warranty; for natural wear arising from the biological ageing of leather, replacement becomes predictable but should not surprise beyond the third year of daily use.
