Frequently asked questions

What is the lug width of the Oris Artelier 01 733 7591 4091-07 5 21 71FC?

The lug width of the Oris Artelier is 21 millimetres. This specification is intrinsic to the 40-millimetre case geometry. Any compatible strap must be constructed to precisely 21 millimetres: 20 millimetres will be too tight, 22 millimetres will have play. Measurement is taken with a digital calliper between the two inner lugs where the spring bar sits.

Which strap do you recommend for the Artelier Oris?

For the Oris Artelier 01 733 7591 4091-07 5 21 71FC, we recommend alligator leather in black or deep brown, or aged shell cordovan as first choice. Both emphasize the formal-sportive readability of the design. Secondarily, vegetable-tanned calf leather with visible grain texture offers balanced aesthetics. For practicality, Cordura canvas NATO straps provide versatility and quick changes. Vulcanized rubber in grey-black is ideal for summer or nautical contexts.

How do I change the strap on my 21-millimetre Artelier Oris?

The procedure is straightforward: examine the caseback of the 01 733 7591 4091-07 5 21 71FC, where you will see two metal lugs with a through-pin. Procure a spring bar tool with bifurcated tip. Position the spring on the first lug downward, extract the pin with the tool's prong, then repeat on the second side. Insert the new strap by sliding the pin into the first lug, then push the spring until it clicks. Repeat for the opposite side. The operation takes three minutes and requires no technical expertise.

Can I use aftermarket-compatible straps on this Oris?

Yes, it is recommended. The Oris Artelier 01 733 7591 4091-07 5 21 71FC accepts any strap constructed to exactly 21 millimetre lug width. Artisanal aftermarket straps in leather, NATO, and rubber allow aesthetic variation without modifying the watch. Compatibility is guaranteed if the width is precisely 21 millimetres and the pins are standard Oris specification (1.5 millimetre diameter, 9 millimetre length). Avoid generic economy straps, which frequently oscillate between 20 and 22 millimetres.

How long does a leather strap last on this watch?

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) under daily wear lasts between 5 and 10 years. Durability depends on climatic use—humidity, perspiration, sun exposure accelerate ageing—and maintenance practice. A naturally treated leather strap, such as vegetable-tanned shell cordovan, improves aesthetically with age, developing patina and warm tones. When the leather begins to crack at the fibres, it signals end-of-life. Replacement with a new strap of the same 21-millimetre lug width is rapid and economical.
