Strap for Oris Classic 01 733 7719 4375

The lug width is 20mm. This is the standard distance between the two lugs of the case where the strap is attached. Always verify with a digital calliper before purchase to exclude minor production variations.

Vegetable-tanned leather, particularly Florentine Tuscan leather, is the primary recommendation for this watch. Traditional Italian tanning develops a natural patina that harmonises with the steel case over time. For versatility, elegant black calf or a technical NATO offer practicality whilst maintaining aesthetic balance.

Position the watch face-down on a soft surface. Locate the lateral lugs and use a spring bar removal tool (or small screwdriver) to push the fixing pin outward, allowing it to emerge. Remove the old strap and insert the new one by aligning the holes with the lugs, then snap the pin back into position.

Yes, provided the lug width is exactly 20mm. Aftermarket straps of superior quality (vegetable leather, NATO, technical rubber) often offer better finishing and materials than OEM straps. Always verify that the supplier specifies the exact width and supplies quality replacement pins.

A quality vegetable-tanned leather lasts 5–10 years with moderate use and regular maintenance (gentle cleaning, natural drying, protection from prolonged water exposure). Durability increases if you frequently alternate between multiple straps, reducing stress on a single material. Leather ageing is part of the aesthetic appeal, not a defect.
