Strap for Oris Rectangular 01 561 7656 4061

The lug width (misura ansa) of the Oris Rectangular 01 561 7656 4061 is 17 millimetres. This dimension ensures balanced proportions relative to the 24-millimetre rectangular case. To verify compatibility with an aftermarket strap, measure the distance between the lug attachment points (centre to centre) using a digital calliper: you should obtain a value between 16.5 and 17.5 millimetres.

The choice depends on usage and context. For formal professional environments, we recommend a calf leather strap with vegetable tanning in dark brown or black, or shell cordovan with golden patina. For daily versatility, a NATO strap in high-density polyamide in grey or blue offers practicality and style. In summer, smooth leather in light tones (pearl grey, cream) maintains visual freshness without compromise. If alternating different contexts, vulcanised rubber in black is the contemporary and timeless choice.

Before proceeding, ensure you work on a clean, soft surface (microfibre cloth). Locate the pins or spring bars connecting the strap to the lugs. Using a dedicated tool (spring bar tool) or a smooth plastic stick, apply gentle pressure to one of the pins to loosen the old strap. Once removed, align the new strap (remembering that the lug width is 17 millimetres) and insert the pins into the lugs, verifying that they click correctly into position. Avoid applying excessive force to prevent damage to the strap or lugs.

Yes, you can use aftermarket straps compatible with 17-millimetre lug width. We recommend always verifying compatibility before purchase by measuring the distance between the lug attachment points. Leather straps with vegetable tanning, calf leather, alligator, rubber, or NATO are fully compatible with the Oris Rectangular 01 561 7656 4061. Using aftermarket straps does not affect the movement warranty, provided the change is made without damaging the watch.

Durability depends on usage intensity, climate, and material. A vegetable-tanned calf leather strap, if subjected to moderate daily wear, maintains elasticity and functionality for 18–24 months before showing initial signs of wear (buckle enlargement, grain cracking). Shell cordovan, thanks to its denser molecular structure, can last 24–36 months. Vulcanised rubber, if exposed to prolonged direct sunlight, degrades more rapidly (12–18 months), whilst high-density polyamide NATO straps exceed 3–4 years without significant wear. Storing the watch in a cool, dry environment and avoiding excessive humidity and sudden temperature variations significantly extends strap life.
