Frequently asked questions

What is the lug width of the Oris Artix GT 01 778 7661 7784-Set LS?

The lug width of the Oris Artix GT is 22mm. This measurement refers to the distance between the two spring bar holes that connect the strap to the case. To verify this precisely, measure the inner diameter of the left lug pin to the inner diameter of the right lug pin using a digital calliper or ruler. Tolerances are minimal: exactly 22mm ensures perfect fit without lateral play.

What is the best strap for the Oris Artix GT?

The optimal choice depends on intended usage. For formal elegance, we recommend an alligator strap with vegetable tanning or cognac calf leather with deployante buckle: the contrast between the soft material and titanium case is compelling. For intense daily use, a nylon ballistic NATO in grey or dark blue offers durability and quick-change capability. For water sports, dark grey FKM rubber with fine grain texture is essential. All these straps are available in the compatible 22mm size.

How do you change the strap on the Oris Artix GT?

To change the strap, you will need a spring bar tool or a small flathead screwdriver. Position the watch on a soft, stable surface with the case back facing upward. Insert the spring bar tool into the hole beneath the lug, then gently press the lateral pin to release the strap from the opposite side. Completely extract the pin and repeat on the other side. For the new strap, align the hole to the left pin, insert the pin from above, and secure the right hole onto the pin. Verify that both sides are fully locked before wearing the watch.

What aftermarket strap is compatible with the Artix GT 01 778 7661 7784-Set LS?

Any strap with a 22mm lug width is compatible, provided the case lugs—the lateral protrusions—have the same width. Milano Straps offers a dedicated collection of 22mm straps in alligator, vegetable-tanned calf, ballistic NATO, and FKM rubber. All are handcrafted to ensure precision tolerances and superior build quality. Verify that the strap is shipped with appropriate keeper loops to maintain aesthetic order.

How long does a leather strap last on the Oris Artix GT?

The lifespan of a leather strap depends on usage intensity and care. A vegetable-tanned calf or alligator strap, worn daily in formal contexts, may last 3–5 years before showing fatigue signs at keeper corner edges. If the watch is used intensely (sports, perspiration, sun exposure), durability reduces to 18–36 months. Factors accelerating wear: constant humidity, intense heat, contact with chemical liquids. To maximise longevity, rotate the strap with others (using NATO or rubber during intense periods) and periodically apply a natural leather conditioner. Patina—the natural ageing of the material—is desirable and does not compromise functionality.
