Strap for BC4 4E RHFS

The lug width of the Oris BC4 01 674 7616 4284-Set is 22mm. This measurement represents the distance between the metal pins (lugs) of the case. To verify compatibility, measure with a calliper the distance between the two case lugs: two parallel marks of 22mm confirm the correct size.

The choice depends on intended use and desired finishing. Natural alligator emphasises the formal vocation; vegetable-tanned calf develops a compelling patina over time; NATO in recycled material enhances the professional character; vulcanised rubber transforms the BC4 into a companion for extreme environments. All these materials are available in 22mm size from Milano Straps.

To change the strap, obtain a bar pin removal tool (a small hammer and pin). Position the watch so one lug is accessible, insert the tool's pin into the slot perpendicular to the lug, and push gently upward to extract the pin. Repeat on the other side, then insert the new strap's pins. The operation takes minutes and requires no technical expertise.

Yes, absolutely. Any strap with a 22mm lug width is compatible. Milano Straps offers an extensive selection of artisanal straps in leather, NATO and rubber, specifically tested for watches of this size. Compatibility is guaranteed by the standard lug width measurement.

Durability depends on material and use. Quality vegetable-tanned calf lasts 3-5 years with routine maintenance (periodic cleaning and annual conditioning). Alligator tends to last longer (5-7 years) due to greater leather density. To extend strap life, avoid prolonged exposure to fresh water, constant humidity and contact with harsh detergents. Milano Straps provides specific preservation guidance.
