Frequently asked questions

What is the lug width of the Louis Erard Excellence 85358TT02.BTT88?

The lug width of the Louis Erard Excellence 85358TT02.BTT88 is 23 millimetres. To verify this measurement, remove the existing strap and measure the internal distance between the two spring bars located at the extremities of the case. Precise measurement is essential for purchasing compatible straps and ensuring correct fit.

Which strap is recommended for the Louis Erard Excellence 85358TT02.BTT88?

For this titanium brushed model, we recommend an alligator strap in cognac brown, which enhances the neutral tonality of the case, or vegetable-tanned calf leather in black for formal contexts. A grey or regimental blue NATO canvas creates an attractive sporty contrast. The 23mm width allows you to exploit an extensive range of high-quality artisanal proposals.

How do you change the strap on the Louis Erard Excellence 85358TT02.BTT88?

To change the strap, you will need a spring bar removal tool. Insert the tool into the small slots beneath the lateral pins of the case, applying light pressure to trigger the retention mechanism. Once the pins compress, the strap can be gently removed. Repeat the procedure from the opposite side and insert the new strap by aligning the holes with the pins.

Are aftermarket straps compatible with the Louis Erard Excellence 85358TT02.BTT88?

Yes, aftermarket straps with a 23mm lug width are perfectly compatible with the Louis Erard Excellence 85358TT02.BTT88. Ensure you verify the lug width precisely before purchase. Milano Straps offers an extensive selection of artisanal straps in leather, alligator, canvas and rubber, all available in the 23mm size specific to this model.

What is the lifespan of a leather strap for the Louis Erard Excellence 85358TT02.BTT88?

A quality leather strap (alligator or vegetable-tanned calf) for the Louis Erard Excellence 85358TT02.BTT88 has an average lifespan of 3-5 years with daily use, provided appropriate maintenance is observed.
