Strap for Big Crown Pointer Date Father Time

The lug width of the Oris Big Crown 01 754 7741 3161-Set is exactly 20 millimetres. This measurement represents the space between the two holes where the strap attaches to the case. Always verify this dimension before purchasing an aftermarket strap.

The Big Crown 01 754 7741 3161-Set pairs exceptionally well with alligator straps featuring vegetable tanning, calf leather, or robust canvas NATO straps. The watch's aviator heritage calls for minimalist strap designs. Avoid excessive ornamentation: the bronze patina requires restraint.

Remove the strap by extracting the spring bars from the lugs. Use a dedicated tool or small pin to lift the internal ferrule of the spring bar and release it from the case. Proceed with caution to avoid scratching the bronze. Patience is essential—never rush this operation.
