The Benu MG-000001, seen from the bench

Frequently asked questions

What is the lug width of the Moritz Grossmann Benu MG-000001?

The Moritz Grossmann Benu MG-000001 features a 20mm lug width. This measurement is specific to the 41mm case proportion and is crucial when selecting a compatible strap. Correct lug width measurement is taken from the outer edge of one lug pin to the outer edge of the other, with the strap removed.

What strap is best suited for the Moritz Grossmann Benu MG-000001 in rose gold?

For a rose gold Benu, an alligator strap with vegetable tanning in deep cognac brown represents the traditional reference choice. Alligator offers the right tensile strength to support the 20mm lug width and develops natural patina harmonising with the ageing of rose gold. Alternatively, vegetable-tanned calf provides better initial elasticity, or a grey anthracite NATO for contemporary solutions.

How do I change the strap on a watch with 20mm lugs?

To change a strap on a 20mm lug watch, you will use spring bars anchoring the strap to the case lugs. With a dedicated spring bar remover tool, apply controlled pressure to one lug pin to release one strap end, then extract the strap. Align the new strap holes with the pins and insert the spring bar until you hear a click. Repeat on the other side. If inexperienced, seek professional strap change service.

Can I use an aftermarket compatible strap on the Moritz Grossmann Benu MG-000001?

Yes, you can use high-quality aftermarket straps in the 20mm size, provided construction meets specifications for thickness and rigidity. Milano Straps offers a range of artisanal straps in leather, NATO and rubber specifically calibrated for the 20mm lug width, ensuring mechanical compatibility and aesthetic coherence with the rose gold Benu.

What is the average lifespan of a leather strap on a watch like the Benu?

The lifespan of a leather strap depends on intensity of use and tanning quality. An alligator strap with vegetable tanning, worn daily, has an average life of 3-5 years before structural wear becomes evident. Calf leather duration is similar. The determining factor is exposure to moisture and perspiration. Moderate use significantly extends lifespan. The patina developing increases aesthetic character even during controlled ageing.
