Strap for Oris Rectangular 01 561 7621 4964

The lug width of the Oris Rectangular 01 561 7621 4964 is precisely 16 millimetres. This measurement represents the distance between the two lugs soldered to the case and is fixed for this reference. Any aftermarket strap must possess exactly this dimension to ensure correct installation without lateral play or forcing. You can verify the measurement using a digital calliper positioned between the two lateral attachments on the case.

For the Rectangular 01 561 7621 4964, alligator leather straps with vegetable tanning represent the most coherent choice from both aesthetic and constructive perspectives. The fine grain texture of alligator naturally complements the rectangular lines of the case. Alternatively, chrome-tanned calf leather with satin finish, natural cotton NATO straps, and FKM rubber offer functional versatility whilst maintaining visual restraint. Your choice depends on intended use: formal elegance for alligator, practicality for NATO and rubber.

The strap is mounted by inserting the lugs into the dedicated slots on the case, secured by spring bars that maintain the strap in position. To remove the original strap, use a dedicated spring bar tool to compress the pins and extract the lug from one end. Position the new strap by aligning the holes with the case lugs, then insert the spring bars. Ensure the strap is fully inserted and the pins are firmly locked in place.

A quality leather strap constructed with vegetable tanning or tannin-chrome tanning, used correctly, has an average lifespan of 3-5 years with moderate daily use. Durability depends on factors such as sun exposure, humidity, frequency of strap rotation, and maintenance. An alligator strap with vegetable tanning develops a desirable natural patina over time, enhancing the aesthetic value of the ensemble. FKM rubber, conversely, possesses superior longevity (7-10 years) as an inert material.
