Frequently asked questions

What is the exact lug width of the Oris Rectangular 01 561 7526 4061-07 5 16 42FC?

The lug width of the Rectangular is 16mm, a non-standard dimension in contemporary watchmaking. This measurement is precisely calculated to match the proportions of the 24mm rectangular case. To verify compatibility, measure the distance between the lateral attachment points of the case: it must correspond exactly to 16mm.

Which strap type do you recommend for the steel Rectangular?

For the Rectangular, we recommend three categories: alligator leather with pronounced grain for vintage authenticity, vegetable-tanned calf for natural elegance and progressive patina, NATO with tight weave for casual versatility. Each choice must respect the Art Deco geometry of the case. Avoid straps with excessively modern textures or light colours, which conflict with the restrained personality of the piece.

How do I change the strap on my Oris Rectangular 01 561 7526 4061-07 5 16 42FC?

Strap replacement is accomplished through removal of the spring bars. Position the watch with the case facing downward, locate the spring bar beneath the lug (a small metal rod with springs at both ends), and use a flat, thin tool to gently compress the spring, freeing the old strap end. Extract the strap and insert the new one, ensuring the spring bar locks securely in both seats. Avoid abrupt movements that could dislodge the delicate attachment points.

Can I use aftermarket straps compatible with other brands on my Oris Rectangular?

No, the 16mm lug width is specific to the Rectangular. Straps manufactured for 18mm, 20mm, or other dimensions will not fit correctly into the case attachment seats. Compatibility requires millimetre precision. We recommend exclusively straps designed and tested for the 16mm lug width, such as those in the dedicated collection on Milano Straps.

How long does a leather strap last on the Rectangular in daily use?

A high-quality leather strap (alligator or vegetable-tanned calf) typically lasts 2-4 years with moderate daily use, developing patina and gradual wear marks. Factors such as frequency of wear, ambient humidity, sun exposure, and personal perspiration influence longevity. A NATO strap, owing to its fibrous composition, can last 4-7 years. To extend strap life, apply protective balms every 6-12 months and store in dry environments when not worn.
