Strap for Artelier Date 31 Stainless Steel - Yellow Gold / Silver

The lug width measures 14mm. This dimension requires precise measurement using a digital calliper, positioned perpendicularly between the internal attachment points of the spring bars on the lugs. A 14mm width is proportionally ideal for compact cases such as the 31mm diameter of this Artelier and ensures visual coherence at the wrist.

An alligator in vegetable tanning or a calf leather with natural ageing are the most appropriate choices for an Artelier of this category. Both materials will evolve over time, developing a patina that integrates with the stainless steel case. For daily versatility, a heavy cotton NATO allows rapid colour changes whilst maintaining constructive elevation.

The strap is changed using a small tool (a spring bar removal tool or microscrewdriver) to depress the springs positioned laterally inside the case at each lug. Once the springs are freed, the lug releases from its seat. Installing the new strap requires aligning the lugs to the holes and pressing until the spring locking mechanism clicks into place. This operation requires patience and precision, particularly with small-format cases.

Yes, aftermarket straps configured for 14mm lugs are fully compatible. It is essential to verify precise lug measurement of your unit before purchase, as minor manufacturing variations could compromise fitting. Bespoke artisanal straps offer maximum aesthetic and functional cohesion with this Oris model.

A high-quality artisanal alligator or calf strap, subject to moderate and consistent use with periodic maintenance (cleaning, protection from heat sources and prolonged humidity), maintains structural integrity for 4–6 years. Vegetable tanning slows natural fibre degradation compared to chrome tanning. Visual ageing is acquired character; structural failure depends on usage intensity and preventive care.
