Strap for Oris Classic 01 561 7718 4071

The lug width (ansa width) of the Oris Classic 01 561 7718 4071 is 14 millimetres. This measurement represents the distance between the two attachment points of the strap on the case and determines compatibility with any aftermarket strap. It is important to measure it directly on your watch using a digital calliper to ensure accuracy.

For a watch with contained proportions like the Classic 01 561 7718 4071, we recommend three primary options: vegetable-tanned alligator for formal elegance with evolving patina, grained calf leather for daily versatility, and technical NATO for those seeking practicality without aesthetic compromise. Rubber represents the modern choice for informal contexts. Your decision depends on your intended use and the personality you wish to convey to the watch.

The procedure requires minimal tools: a spring bar tool (bayonet-style extractor) and gentleness. Position the tool in the lateral slots of the lugs, exert light pressure to release the spring bars, and slide the old strap out of the lugs. Insert the new strap ensuring the springs engage correctly in their housings. If you lack experience, Atelier Casati Milano offers strap changes by appointment at no additional cost for customers purchasing from milanostraps.it.

Yes, any strap with a 14-millimetre lug width is technically compatible. However, we recommend verifying the strap thickness (typically between 4 and 5 millimetres) and the type of buckle or deployante clasp to ensure aesthetic coherence with the watch's proportions. milanostraps.it artisanal straps are designed to respect these specific proportions.

A quality leather strap (alligator, calf, shell cordovan) with vegetable tanning typically lasts 5 to 10 years of regular wear, conditioned by frequency of use, sun exposure, and climate. Leather evolves, developing a characteristic patina that testifies to its use. milanostraps.it artisanal straps utilise leather from established suppliers, guaranteeing longevity superior to industrial straps. Periodic maintenance (cleaning, drying) significantly extends lifespan.
