Frequently asked questions

What is the lug width of the Norqain Adventure NNB1001BBWA/IL107-DLC?

The lug width of the Norqain Adventure NNB1001BBWA/IL107-DLC is 20mm, a specific dimension requiring dedicated straps. To verify compatibility, measure the distance between the inner edges of the left and right lugs: the value must match exactly 20mm. This precision is essential to avoid aesthetic gaps or fitting issues.

Which strap is most suitable for the Norqain Adventure NNB1001BBWA/IL107-DLC?

For this Swiss field watch, we recommend straps in vegetable-tanned alligator, which emphasise the minimalist character of the case. Alternatively, vegetable-tanned calf leather develops natural patina over time, or NATO straps in cotton-linen for intensive use. The choice depends on the balance desired between formal elegance and sporting practicality.

How do I change the strap on the Norqain Adventure NNB1001BBWA/IL107-DLC?

The strap is replaced by extracting the spring bars that connect the strap to the case. Use a dedicated spring bar tool: insert the tip into the release lever slot and apply slight upward pressure to free the pin. Repeat the operation on both lug attachments. Install the new 20mm strap by reversing the procedure, ensuring the pins are correctly seated.

Can I use a quality aftermarket strap on this watch?

Yes, absolutely. The Norqain Adventure NNB1001BBWA/IL107-DLC accepts aftermarket straps of any material—provided the lug width is exactly 20mm. Artisanal leather straps with vegetable tanning offer superior value compared to original straps, with the possibility of colour and buckle customisation (pin buckle, deployante, folding buckle).

How long does a leather strap last on this watch?

An artisanal leather strap with vegetable tanning has an average lifespan of 4-7 years with daily use, influenced by exposure to perspiration, humidity and UV rays. The Norqain Adventure, given its versatile intended use (urban and sporting), benefits from straps that age gracefully: the natural patina they develop emphasises the character of the watch. To extend durability, alternate use with different straps and protect the leather during intensive water activities.
