Strap for Oris Rectangular 01 561 7693 4031

The lug width (misura ansa) of the 01 561 7693 4031 model is 22 mm. This measurement is critical when selecting a compatible strap. Lug width refers to the distance between the pins that connect the strap to the case. Selecting an incorrect width (such as 20 mm or 24 mm) will render the strap unusable. We recommend verifying the measurement personally with a ruler, or consulting official Oris documentation.

For the Rectangular 01 561 7693 4031, Mississippi alligator in natural brown or black represents the most elegant choice, perfectly aligned with the Art Déco design philosophy of this model. The authentic alligator texture emphasizes the rectangular geometry of the case. Alternatively, barenia calf, vegetable-tanned chromatic leather, or a robust cotton NATO offer aesthetic and functional versatility whilst maintaining the formal character of the timepiece.

To change the strap, you'll need a small spring bar tool with a ball-shaped tip. Position the watch on a soft surface and observe the pins at the lugs—these small metal cylinders connect the current strap to the case. Using the tool, gently press downward on one side: the pin will retract, allowing you to remove the strap. Repeat on the other side. Install the new strap by aligning its slots with the pins, then press firmly until you feel a definitive click. The entire operation takes just a few minutes and requires no prior experience.

Absolutely. The Oris Rectangular 01 561 7693 4031 is compatible with any quality strap featuring a 22 mm lug width. Aftermarket straps—particularly those crafted from artisanal alligator, vegetable-tanned leather, or natural rubber—often offer construction quality equal to or exceeding factory Oris straps, at lower cost and with greater creative freedom. It is essential to verify material authenticity (genuine alligator, not synthetic) and construction precision.

Longevity depends on leather type and usage patterns. A genuine alligator strap, worn daily, maintains structural integrity for 3–5 years before visible wear appears (colour shifts, micro-cracking). Vegetable-tanned calf exhibits similar durability. Chromatic leather lasts 4–7 years with proper maintenance. Natural rubber, whilst not leather, typically performs for 2–3 years before natural hardening occurs. Factors that reduce lifespan: constant humidity exposure, aggressive perspiration, lack of periodic cleaning. To extend durability, avoid wearing the strap in showers and apply leather conditioner 2–3 times annually.
