Strap for Oris Classic 01 733 7719 4371

The lug width of the Oris Classic 01 733 7719 4371 is 20mm. This measurement represents the distance between the two lugs (spring bar guides) that attach the strap to the watch case. To verify this measurement correctly, place a ruler from the centre of the metal pin on one lug to the centre of the pin on the opposite lug. Any strap compatible with this width will fit perfectly into the lugs without play or forcing.

Tuscan leather produced using vegetable tanning is the most congruent choice with this watch's aesthetic and constructive philosophy. The natural texture and irregular grain of bovine leather maintains the sober, functional character of the Classic without the regular geometry that characterises materials such as alligator. Alternatively, a NATO strap in tightly woven fabric, such as Military Grey or Carbon Black, preserves minimalist simplicity whilst adding pairing versatility. For summer use, FKM rubber remains a practical and elegant proposal.

Changing the strap on this watch requires the use of a spring bar removal tool. Procedure: position the watch on a flat surface with the case back visible, locate the two lugs (lateral guides), insert the sharp tip of the removal tool into the groove beneath each lug, apply slight pressure to compress the internal spring, and simultaneously pull the strap away. Once the old strap is removed, align the new 20mm strap with the lugs and gently push until the spring locking mechanism clicks into place. Avoid forcing to prevent damage to the lugs.

Yes, the Oris Classic 01 733 7719 4371 accepts any aftermarket strap produced to the 20mm lug width standard. This measurement is widely available on the market, offering considerable variety in materials and styles: leather (Tuscan, Italian, French), NATO fabrics, technical rubber, and even shell cordovan. The important thing is to verify that the strap is genuinely calibrated for 20mm and that the spring bars used are compatible with the lug holes.

A quality leather strap, produced using vegetable tanning such as Tuscan or Italian calf, has an average lifespan of 3-5 years under standard daily use conditions. Longevity depends on factors such as exposure to body sweat, environmental humidity, maintenance frequency, and intensity of use. A strap frequently exposed to hot, humid climates will age faster; conversely, seasonal use and regular maintenance (cleaning with a damp cloth, air drying) can extend life to 7-10 years. The natural patina that develops over time does not represent structural degradation, but rather a sign of authentic use.
