FAQ
What is the lug width of the Oris Rectangular 01 561 7656 4034-07 5 17 71FC?
The lug width (anse width) of this Oris model is precisely 17mm. This specific measurement is critical when selecting a compatible strap: standard 18mm or 20mm straps cannot be used without risking imprecise contact with the lugs. Correct measurement is performed by positioning a digital calliper perpendicular to the inner shoulders of both lugs.
Which strap material is most suitable for the Rectangular Oris?
For the Rectangular, we recommend alligator with vegetable tanning for those seeking aesthetic evolution over time; European calf leather (Hermès, Tuscan) for stable elegance; cotton NATO for sporty versatility. Rubber remains the technical choice for aquatic activities. The vertical geometry of the case is enhanced by leather straps with visible texture, which amplifies the optical depth of the rectangular case.
How do I safely change the strap on the Oris Rectangular?
Use of a spring bar remover tool is essential. Position the watch on a soft surface with lateral visibility, gently press the spring bar inward with the tool, carefully extract one end, then repeat from the opposite side. The operation must be slow to avoid scratches on the case and accidental loss of the spring bar. For 17mm lugs, use only certified spring bars with 17mm external diameter.
Can I use an aftermarket strap from other brands that claims 17mm compatibility with the Rectangular Oris?
Only if the lug width is identical (17mm) and the attachment has no micro-tolerance variations. Many Chinese manufacturers claim false compatibility; we recommend exclusively 17mm-certified straps from recognised European producers or specialised artisans who guarantee manual compatibility verification. Absolutely avoid universal straps with elastic openings, which compromise the aesthetic precision of the Rectangular.
How long does a leather strap last on the Oris Rectangular under normal conditions?
A quality leather strap (vegetable-tanned alligator or European calf) withstands 3–5 years with moderate daily use (4–5 days per week). Durability increases if rarely exposed to water and humid environments, and if subjected to occasional maintenance with natural creams. Vegetable tanning develops natural patina without structural weakening until the 5th–6th year. Rotation with other straps significantly extends useful life.
