Strap for Oris Classic 01 561 7718 4373

The lug width (ansa width) of the Oris Classic 01 561 7718 4373 is 14mm. This measurement refers to the internal space between the lugs of the case where the strap attaches. It is essential to measure the lug width and not confuse it with the total strap width, which may be slightly larger if it has side edges. For this model, the 14mm lug width is mandatory to ensure perfect fit and secure fastening.

For the Classic 01 561 7718 4373 with its 28.5mm case diameter, fine leather straps (alligator, shell cordovan with vegetable tanning) are recommended for formal aesthetics, or medium-thickness calf leather for daily versatility. For sporty use or humid climates, heavy-duty NATO canvas or vulcanised rubber straps offer practicality and durability. Your choice depends on the intended context: leather for elegance, textile or rubber for functionality.

To change the strap, you will need specialist tools (spring bar removal pins, small hammer and support block) to extract the pins connecting the strap to the lugs. It is advisable to practise on a less valuable watch before working on the Classic 01 561 7718 4373. Alternatively, contact an authorised Oris service centre or a specialised watchmaker. Always verify that the new strap has a 14mm lug width to ensure perfect compatibility.

Any strap with a 14mm lug width is compatible with the Oris Classic 01 561 7718 4373. The market offers numerous alternatives in leather (calf, alligator, shell cordovan), textile (NATO, canvas) and rubber. Your choice depends on aesthetic preference and intended use. We recommend purchasing from specialised suppliers who guarantee build quality and documented compatibility with 14mm lugs.

The lifespan of a leather strap depends on material quality and intensity of use. A good-quality calf leather strap typically lasts 3–5 years with regular daily wear, whilst shell cordovan with vegetable tanning can exceed 7–10 years thanks to greater resistance to cracking. Prolonged exposure to sunlight, moisture and perspiration shortens strap life. Regular maintenance (cleaning and periodic conditioning) significantly extends longevity. Textile or rubber straps have variable lifespans but generally shorter than noble leathers.
