FAQ

What is the lug width of the Oris Rectangular 01 561 7783 4063-07 5 19 16?

The lug width (ansa width) of this model is 19mm. This is the distance between the two pins that support the strap. It is essential to measure this accurately before purchasing an aftermarket strap to ensure mechanical compatibility and prevent damage to both the strap and the watch case.

Which strap is most recommended for the Oris Rectangular 01 561 7783 4063-07 5 19 16?

The choice depends on primary use. For formal or business contexts, a strap in alligator or vegetable-tanned calf leather represents the most elegant combination. For daily and sports use, a technical NATO or FKM rubber guarantee practicality and durability. Atelier Casati Milano recommends evaluating your personal wardrobe and intended use before deciding on material and colour.

How do you change the strap on an Oris Rectangular 01 561 7783 4063-07 5 19 16?

Strap replacement requires the use of a dedicated tool (spring bar tool) and the ability to extract the pins without scratching the case. If you are not an experienced hand, it is advisable to consult a qualified watchmaker. Atelier Casati Milano offers personalized consultations and can assist with the installation of artisanal straps by appointment.

Is there an aftermarket strap compatible with the 19mm lug width?

Yes, milanostraps.it offers a complete collection of handcrafted Italian straps in 19mm: alligator, calf, NATO and rubber. All straps are available with snap or screw-down deployment clasps, ensuring mechanical security and total compatibility with the Oris Rectangular. Shipping is fast and online customization is available.

How long does a leather strap last on the Oris Rectangular 01 561 7783 4063-07 5 19 16?

Durability depends on material, tanning process and usage. A strap in vegetable-tanned calf leather lasts on average 3-5 years under normal daily conditions. Alligator, being more robust, can last 5-7 years. FKM rubber offers superior longevity (7-10 years) in harsh environments. Proper maintenance, drying after water contact and protection from heat sources significantly extend the useful life of the strap.
