Strap for Classic Date 42 Stainless Steel / Silver

The lug width of the Oris Classic 01 733 7594 4061-07 5 20 12 is 20mm. It is measured at the strap attachment points on the case, between the two inner walls, and accommodates straps in leather, fabric, and rubber of the same width. This is a classic standard that permits considerable variety in style and material interpretations.

For the Oris Classic 01 733 7594 4061-07 5 20 12, alligator leather with vegetable tanning is the most authentic choice, as it reinforces the watchmaker's artisanal identity. Hammered or satin calf leather represents a versatile and robust alternative. For a sportier character, a grey or navy NATO fabric strap integrates functionality and balanced aesthetics. FKM rubber with fine grain texture is ideal for those prioritising resistance to environmental exposure and daily practicality.

The strap on the Oris Classic 01 733 7594 4061-07 5 20 12 is replaced by removing the metal lugs from the lug seats, sliding out the old strap and threading the new one through the same seats. If the strap is secured with a deployante or integrated buckle, unscrew or open the fastening mechanism and reinsert the new strap. Perform this operation on a soft, clean surface to avoid scratching the stainless steel case.

An alligator leather strap tends to last beyond 7 years, developing characteristic patina and texture over time. Hammered calf leather straps offer intermediate durability. All leather materials require periodic maintenance and protection from excessive moisture to preserve elasticity and colour finish.
