The Artelier 01 733 7670 4051-07 5 21 70FC, seen from the bench

The Oris Artelier 01 733 7670 4051-07 5 21 70FC is a 40mm stainless steel watch with a silver dial, powered by the manual-wind Oris 733 calibre. It features a lug width of 21mm and represents a minimalist approach to Swiss watchmaking, with visible caseback and readable dauphine hands. The stainless steel case ensures durability and develops a refined patina over time without problematic oxidation.

Frequently asked questions

What is the lug width (ansa width) of the Oris Artelier 01 733 7670 4051-07 5 21 70FC?

The lug width is exactly 21 millimetres. This measurement refers to the distance between the two lugs (the eyelets where the strap attaches to the case). To verify, use a callipers to measure the internal distance between the two lugs with the watch positioned case-downwards. A 21mm strap is the only correct fit for this model; incorrect dimensions will result in poor fitment and instability.

Which leather strap do you recommend for the Oris Artelier?

Vegetable-tanned calf leather represents the optimal choice for daily wear: soft on the wrist after the first 48 hours, it develops a natural patina that increases character, and resists 5–8 years with proper maintenance. Alternatively, alligator (especially in burgundy, brown or black) offers superior sophistication for semi-formal occasions. For maximum longevity and long-term investment, shell cordovan in 1.6–1.8mm thickness is practically indestructible and ages magnificently.

How do I change the strap on my Oris Artelier 01 733 7670 4051-07 5 21 70FC?

The watch uses fixed lugs (non-folding). To remove the strap: place the watch on a soft surface, locate the metal pin (spring bar) that passes through the lug, use a dedicated tool (spring bar tool) to gently push the pin downwards while simultaneously extracting the strap. To install the new strap: align the strap eyelets with the case lugs, insert the pin manually, use the spring bar tool to compress the pin and secure it firmly. The operation takes 3–5 minutes for an experienced hand.

Is an aftermarket strap compatible with this Oris Artelier?

Yes, any strap with a 21mm lug width is geometrically compatible. However, the construction quality of the strap must respect the sober elegance of the Artelier: we advise against rough synthetic straps, glossy plastics, or excessive decoration. Milanostraps' selections specifically curated for this lug width guarantee both compatibility and aesthetic coherence with the Swiss watch. Always verify that the pin (spring bar) is of standard diameter 1.8–2.0mm.

What is the lifespan of a leather strap on a daily-worn watch?

A vegetable-tanned calf strap typically lasts 5–8 years with daily wear (8–12 hours daily), depending on personal perspiration, ambient humidity, and maintenance. Shell cordovan reaches 10–15 years. Alligator sits at 7–10 years. To extend lifespan: dry the strap after rain exposure, apply a cream conditioner (not spray) every 6–8 months, avoid prolonged direct sunlight which accelerates ageing. When the strap begins to crack along the folds, replacement is recommended for safety and aesthetic reasons.
