Frequently asked questions

What is the lug width of the D. Dornblueth & Sohn 99.1 (1) RG?

The lug width of the D. Dornblueth & Sohn 99.1 (1) RG is 22mm. This dimension represents the distance between the inner shoulders of the lugs and determines the width of any compatible strap. Precise measurement is essential to ensure proper fitment without play or binding.

Which strap type pairs best with the D. Dornblueth & Sohn 99.1 (1) RG?

The D. Dornblueth & Sohn 99.1 (1) RG, given its minimalist philosophy, harmonises exceptionally well with alligator in vegetable-tanned honey-amber or grained calf leather. Alligator reflects the formal clarity of the case, whilst calf introduces an organic texture that echoes the watchmaking craftsmanship. Canvas NATO straps equally preserve the understated aesthetic of the piece.

How do you change the strap on the D. Dornblueth & Sohn 99.1 (1) RG?

Strap replacement is accomplished by releasing the locking pins (spring bars) at the extremities of the lugs. Using an appropriate tool, depress the inner pin, extract the worn strap, and insert the new one, ensuring both pins engage properly. For the 99.1 (1) RG, consultation with a specialist is recommended to avoid scratching the rose gold case.

Are aftermarket straps compatible with the D. Dornblueth & Sohn 99.1 (1) RG?

Yes, all straps featuring a 22mm lug width are compatible with the D. Dornblueth & Sohn 99.1 (1) RG. It is imperative to verify that your strap presents this exact dimension. Milano Straps provides a comprehensive selection of artisanal 22mm straps in Tuscan leather, alligator, shell cordovan, and NATO, all tested to guarantee compatibility and construction quality.

What is the typical lifespan of a leather strap for the D. Dornblueth & Sohn 99.1 (1) RG?

Strap longevity depends on usage patterns, maintenance, and material quality. A high-grade strap in vegetable-tanned Tuscan leather typically endures 3–5 years of daily wear before exhibiting aesthetic deterioration. Shell cordovan, owing to its superior density, can perform for 5–7 years. Regular maintenance—gentle cleaning, natural drying, and occasional protective treatments—significantly extends service life.
