Strap for Oris Classic 01 561 7650 4351

The Oris Classic 01 561 7650 4351 features an exactly 14mm lug width. This non-standard dimension is specific to the compact proportions of the 28.5mm case and should be verified by measuring the distance between the inner case lugs with a calliper.

An alligator strap in dark brown or black represents the utmost choice of elegance for this model. Alternatively, vegetable-tanned calf leather develops rich patina over time. For daily wear, cotton NATO straps offer versatility whilst maintaining proportions suitable for the compact case.

Position the watch face-down on a soft surface. Locate the attachment pins (spring bars) at the lug ends. Use a dedicated strap change tool or thin needle, press the pin inward to release the old strap, then slide the new 14mm strap inside the same pin until you hear the locking click.

Any strap with a 14mm lug width is compatible with this Oris model. Milano Straps offers a dedicated selection of handcrafted 14mm straps in leather, NATO and rubber, manufactured to quality standards specific to this non-standard lug width.

A quality leather strap, subject to proper maintenance, lasts an average of 4-7 years with daily wear. Durability depends on frequency of use, moisture exposure and periodic application of protective balms. Vegetable-tanned alligator straps develop characteristic patina over time, improving aesthetically.
