Frequently asked questions

What is the lug width of the Oris Rectangular 01 561 7783 4065-07 5 19 17?

The lug width is 19 mm. This measurement represents the distance between the inner base of the left lug and the inner base of the right lug. It is the essential parameter when selecting a compatible watch strap. Any strap intended for this Oris model must have a 19 mm lug width to ensure correct fit and security.

What is the best strap for the Oris Rectangular 01 561 7783 4065-07 5 19 17?

The choice depends on intended use and personal preference. For formal contexts, alligator in dark brown or black tones emphasises the geometric elegance; shell cordovan offers colour depth and distinctive patina development. For versatile daily wear, vegetable-tanned calf leather provides initial softness and durability. A NATO-style cotton strap in heavy gauge represents the contemporary option and is extremely versatile, ideal for warm climates.

How do I change the strap on the Oris Rectangular 01 561 7783 4065-07 5 19 17?

The procedure requires a dedicated tool (spring bar tool) to remove the two elastic pins (spring bars) that connect the strap to the lugs. Position the tool in the groove, compress the spring bar slightly, extract the strap from the first lug. Repeat on the other side. To install the new strap, insert the compressed spring bar into the hole of the new band, align with the lug, release. Verify proper centering.
