Frequently asked questions

What is the lug width of the Blancpain Léman 2041-1230-64B?

The lug width of the Blancpain Léman 2041-1230-64B is 22 millimetres. This measurement is specific to this model and is taken between the inner edges of the lug shoulders on the case. All straps with a 22mm lug width are compatible with this timepiece.

Which strap material is most suitable for the Blancpain Léman 2041-1230-64B?

For the Blancpain Léman 2041-1230-64B, we recommend straps in vegetable-tanned calf leather (such as our Tuscan Supreme Leather in antique tobacco) or genuine alligator in dark tones. Both materials enhance the sporty-elegant character of the titanium case. For greater versatility, a natural rubber strap offers durability and ease of use without aesthetic compromise.

How do I change the strap on this watch?

To change the strap on your Blancpain Léman 2041-1230-64B: remove the watch from your wrist, place the case on a soft surface, locate the lug shoulders (small lateral pins), gently lift the internal pin using a spring bar tool, remove the old strap, insert the new 22mm strap, and reinsert the pin. If you are uncertain, consult a professional watchmaker.

Can I use an aftermarket strap that is compatible with my Léman?

Yes, the Blancpain Léman 2041-1230-64B is fully compatible with high-quality aftermarket straps provided they have a 22mm lug width. Milano Straps offers artisanal straps crafted from noble materials (alligator, vegetable-tanned calf, shell cordovan) that fit this model perfectly.

How long does a leather strap last on a watch like the Blancpain Léman?

A high-quality leather strap (vegetable-tanned or genuine alligator) on a watch such as the Léman, worn daily, typically lasts 3-5 years. The factors affecting longevity are: frequency of wear, exposure to sunlight and humidity, and periodic maintenance. Milano Straps provides straps with an 18-month guarantee on manufacturing defects and recommends rotating between multiple straps to extend the lifespan of each.
