Frequently asked questions

What is the lug width of the Berneron Mirage M34LL?

The lug width of the Berneron Mirage M34LL is 18 mm. This measurement represents the distance between the two case lugs where the strap attaches. Compatible straps must be exactly 18 mm wide to ensure perfect fitment without play or forcing.

What is the best strap for the Berneron Mirage M34LL?

For the M34LL in white gold, the best strap choice is alligator leather with vegetable tanning in neutral tones such as stone grey or honey. This material dialogues beautifully with the precious case, creating a rare aesthetic harmony. Alternatively, shell cordovan or grey pearl satinised calf leather offer excellent chromatic results whilst maintaining absolute refinement.

How do I change the strap on my Berneron Mirage M34LL?

Strap changes are accomplished using spring bars that connect the strap to the case. Using a dedicated tool (spring bar tool), insert the pin into the lateral hole of the lug, releasing the spring tension. The old strap detaches easily. The new 18 mm strap is attached in the same manner, ensuring the spring bars are securely locked on both sides of the case.

Can I use an aftermarket strap with my Mirage M34LL?

Yes, absolutely. The Berneron Mirage M34LL is compatible with any high-quality aftermarket strap featuring an 18 mm lug width. Numerous artisanal manufacturers offer premium 18 mm straps in alligator, shell cordovan, calf leather and NATO options, allowing you to personalise your watch according to your stylistic preferences and usage requirements.

How long does a leather strap last on my watch?

The lifespan of a leather strap depends on material quality and usage conditions. A high-quality artisanal strap in alligator or shell cordovan can last 5-10 years with proper care, especially if not constantly exposed to moisture or temperature variations. Vegetable-tanned leather tends to patina and improve with age, making the strap increasingly fascinating over time.
