Frequently asked questions

What is the lug width of the Moritz Grossmann Benu MG-000779?

The lug width of the Moritz Grossmann Benu MG-000779 is precisely 18 mm, measured internally between the two spring bars. This measurement represents the maximum space the strap must occupy. The external width of the strap attachment pad should not exceed 17.8 mm to ensure seamless integration with the white gold case lugs.

Which strap is most suitable for the Moritz Grossmann Benu MG-000779?

For the Benu MG-000779 in white gold, genuine alligator leather with vegetable tanning is the most coherent choice. Its fine grain creates sophisticated contrast with the case geometry. Alternatively, vegetable-tanned calf offers a patina that ennobles over time, whilst shell cordovan is ideal for those seeking declared elegance. Avoid synthetic rubber, as chemical reactivity accelerates white gold oxidation.

How do I replace the strap on a Moritz Grossmann Benu?

Strap replacement requires removal of the spring bars from the case lugs. Use a dedicated spring bar tool: insert the lever into the small lateral slot of each bar, applying gentle inward pressure to compress the spring. Extract the old bar, align the new strap's attachment pad with the lug holes, and reinsert the bar until it clicks into position. If inexperienced, consult a professional: the Benu deserves conscientious maintenance.

Can I use an aftermarket compatible strap on this model?

Yes, any strap with an 18 mm lug width is compatible with the Moritz Grossmann Benu MG-000779. However, manufacturing quality directly influences user experience and longevity. Artisanal leather straps with traditional tanning age nobly, whilst industrial alternatives show premature wear. For a timepiece of this calibre, a high-quality aftermarket strap enhances the investment.

How long does a leather strap last on this watch?

Lifespan depends on material and usage. Genuine alligator with vegetable tanning maintains structural integrity for 5-7 years under regular moderate wear. Vegetable-tanned calf lasts 4-6 years before aesthetic replacement becomes necessary. Shell cordovan, owing to superior natural density, resists up to 8 years. Critical factors are: prolonged direct sunlight exposure, constant humidity, and lack of periodic leather conditioning. Monthly cleaning with a damp cloth significantly extends functional life.
