Strap for Oris Classic 01 561 7650 4331

The lug width of the Oris Classic 01 561 7650 4331 is 14mm, measured horizontally between the two horizontal spring bar holes on the case lugs. This dimension ensures compatibility with aftermarket straps specifically engineered for a 28.5mm case diameter.

For the 01 561 7650 4331, we recommend an alligator strap with vegetable tanning, grey vitello calf leather, or cotton NATO webbing. Dark grey mélange alligator amplifies the geometric severity of the case, vitello offers a smooth and compact texture, whilst cotton NATO provides a sports-oriented alternative. Avoid highly polished materials that contrast with the restrained aesthetic of the watch.

The strap on the 01 561 7650 4331 is replaced via two horizontal spring bar pins positioned at the case lugs. Use a spring bar removal tool to gently disengage the elastic spring mechanism from below, then slide the pin upward to extract the worn strap. Repeat symmetrically on the opposite lug. Installation of the new strap follows the reverse process: insert the pin through the strap loops, verify the spring is correctly positioned in its housing, and press until it locks.

Yes, the 01 561 7650 4331 is fully compatible with any quality aftermarket strap featuring a 14mm lug width. Milanostraps.it offers an exclusive selection of leather, alligator, shell cordovan and NATO straps, all precisely dimensioned for this reference. Choosing an aftermarket strap permits complete aesthetic personalisation without any mechanical compromise to the case.

A natural leather strap, with daily wear and ordinary care, maintains structural integrity and colour for 2–4 years. Durability depends upon intensity of use, climatic conditions (humidity, solar exposure), and maintenance frequency. Vegetable-tanned leathers, such as Hermès alligator or English Bridle calf, develop a distinguished patina over time and may exceed 5 years longevity if protected from excessive moisture. Avoid prolonged water immersion, even though the 01 561 7650 4331 offers 50 metres water resistance.
