Strap for Artelier Complication 40 Stainless Steel / Silver / Bracelet

The Oris Artelier 01 781 7729 4031-07 8 21 79 features a lug width of exactly 21 millimetres. This dimension is measured in the internal space between the two lugs of the case and represents an intermediate size, ideal for 40-millimetre cases. It is essential to use straps specifically manufactured for this tolerance to ensure a perfect fit without gaps or forcing.

For the Artelier we recommend three options based on usage: 1) Shell Cordovan for those desiring leather that ages gracefully with deep patina; 2) Taurine leather in vegetable tanning for daily versatility and natural patina development; 3) NATO strap in ballistic canvas for absolute practicality and water resistance. The choice depends on the primary context of use: formal, everyday or outdoor.

Strap replacement on the Oris Artelier is accomplished through the spring bars (lugs) that connect the strap to the case horns. Use a small hammer and a pin remover tool, available from professional watchmakers or online. Gently remove the pin from the outer side, extract the old strap and insert the new one, ensuring that the lug is perfectly aligned to the stated 21 millimetres. It is recommended to consult a professional watchmaker for the first changes.

Yes, any strap manufactured for a 21-millimetre lug width is theoretically compatible with the Artelier. However, we recommend artisanal straps that respect precise tolerances: some industrial straps may present minor variations that, although fitting into the spaces, compromise final aesthetics. Always verify that the strap has been specifically manufactured for the 21mm size and that the width is consistent along its entire length.

A quality leather strap worn daily has an average lifespan of 18–30 months. Shell Cordovan and vegetable-tanned leather extend this duration due to fibre density; strap thickness and stitching quality are critical factors. Lifespan also depends on environmental humidity, direct sunlight exposure and hygiene: sweat and water accelerate wear. With regular maintenance and strap rotation during summer months, useful life can extend beyond three years.
