Frequently asked questions

What is the lug width of the Oris Artelier 01 645 7596 4051?

The lug width of the Oris Artelier 01 645 7596 4051 is 24mm. This measurement is taken between the inner shoulders of the integrated lugs on the case and is proportionate to the 45mm case diameter. To verify the measurement, use a calliper positioned perpendicular to the watch between the lugs.

What strap material is recommended for the Oris Artelier 01 645 7596 4051?

For the Oris Artelier 01 645 7596 4051, we recommend high-quality leather straps with vegetable tanning, such as black alligator or structured calf leather. These materials enhance the formal character of the dress watch whilst maintaining aesthetic coherence with the minimalist case design. Alternatively, thick rubber straps transform the timepiece into a more pragmatic travel companion for everyday use.

How do I change the strap on the Oris Artelier 01 645 7596 4051?

To change the strap on the Oris Artelier 01 645 7596 4051, use a spring bar removal tool: insert the flat end beneath the spring bar (the elastic pin connecting the strap to the lugs), push laterally to compress the spring, remove the old strap and insert the new one. Repeat on the opposite side. If you lack experience, consult a specialised watch repair centre.

Is an aftermarket strap compatible with the Oris Artelier reference 01 645 7596 4051?

Yes, any strap with a 24mm lug width is compatible with the reference 01 645 7596 4051. Ensure the strap thickness is proportionate (approximately 3.5–4.5mm) to guarantee proper spring bar engagement and a harmonious transition from case to wrist. Straps that are too thin or too thick compromise overall aesthetics.

How long does a natural leather strap last on an Oris Artelier?

A naturally-tanned leather strap on an Oris Artelier has an estimated lifespan of 3–5 years with intensive daily use, or 5–10 years when rotated among multiple timepieces. Longevity depends on leather quality, ambient humidity and frequency of use. Vegetable-tanned leather develops patina over time, evolving aesthetically; minimal maintenance (gentle cleaning, annual conditioning) significantly extends strap life.
