The Oris Classic 01 733 7719 4371-07 5 20 32 exemplifies conscious Swiss watchmaking tradition with essential design and no superfluous complications. The 42mm stainless steel case houses the Oris caliber 733 automatic movement displaying hours, minutes, seconds, and date through a sapphire caseback. The 20mm lug width ensures balanced proportions and precise strap compatibility, while 316L steel provides corrosion resistance and natural patina development over time.

Frequently asked questions

What is the lug width of the Oris Classic 01 733 7719 4371-07 5 20 32?

The lug width is 20mm. This means the strap must be exactly 20mm wide at the mounting point to the case lugs. An incorrectly sized strap will not fit properly and compromises both aesthetics and wearing security. Always verify the lug width before purchasing a replacement strap.

Which strap material is best suited for the Oris Classic 01 733 7719 4371-07 5 20 32?

Material choice depends on usage and aesthetic preference. For formal contexts, we recommend sliced alligator or shell cordovan. For daily wear, Italian vegetable-tanned calf develops beautiful patina over time. A NATO canvas strap offers sporting versatility. FKM rubber ensures durability in humid or aquatic environments. All materials are compatible with this 20mm lug width.

How do you change the strap on this Oris watch?

The Oris Classic features removable lugs. Use a spring bar tool to gently remove the spring bar securing the strap to the lugs. Insert the new 20mm strap under the spring bar, ensure symmetrical positioning, and reinsert the spring bar until you hear a slight click. Avoid forcing to prevent case damage. Milanostraps supplies pre-assembled straps ready for installation.

Is an aftermarket 20mm strap truly compatible with the Oris Classic 01 733 7719 4371-07 5 20 32?

Yes, provided the lug width is precisely 20mm and strap thickness is proportionate (typically 3-4.5mm). Milanostraps artisanal straps are constructed specifically for this measurement, guaranteeing perfect fit and superior build quality compared to mass-produced alternatives. Compatibility is complete with standard Oris lugs.

How long does a leather strap last on a 42mm Oris like this one?

Longevity depends on material and usage. A vegetable-tanned calf strap worn daily typically resists visible wear for 2-4 years. Shell cordovan can last 5-7 years or longer due to natural leather density. Alligator offers comparable durability to calf. Factors including perspiration, humidity, and wearing frequency affect lifespan. Regular maintenance—cleaning and conditioning—significantly extends strap life.
