Strap for Oris Rectangular 01 561 7692 4031

The lug width of the Oris Rectangular 01 561 7692 4031 is 18mm. This measurement, taken from spring bar to spring bar, is specific to this model and represents the ideal proportion for maintaining visual balance between the rectangular case and the strap. All compatible straps must have exactly 18mm lug width.

The finest choice for the Rectangular is Mississippi alligator leather in natural brown tonality. The wide and symmetrical scale pattern of this material echoes the linear geometry of the case, amplifying its formal vocabulary. Alternatively, black calfskin offers a more discrete yet equally elegant option, particularly suited to formal occasions.

To change the strap, you require a spring bar tool. Gently remove the spring bars from the holes located at the case extremities by inserting the tool beneath the spring. Fully extract the original strap, then align the new strap and secure the spring bars into position. Verify the strap is properly locked on both sides.

Any strap with an 18mm lug width is mechanically compatible with the Rectangular. Options include alligator leather, calfskin, shell cordovan, cotton NATO, heavy canvas, and FKM rubber. Mechanical compatibility is guaranteed by width, whilst material choice depends upon desired aesthetics and intended use.

A quality leather strap (alligator or calfskin) typically lasts 3-5 years under daily wear, depending upon exposure to moisture, perspiration, and mechanical stress. Vegetable-tanned leather offers greater longevity than modern tannery methods. Proper maintenance (periodic cleaning and conditioning) significantly extends the useful life of the strap.
