Strap for 99.2

The lug width (ansa width) of the D. Dornblüth & Sohn 99.2 (07) ST is 22 millimetres. This measurement is critical for strap compatibility and is calculated by measuring the distance between the two metal lugs (spring bar holes) that hold the strap to the case.

For a timepiece of German purism such as the 99.2 (07) ST, we recommend a vegetable-tanned leather strap (e.g., Firenze leather) that develops patina over time and reflects the minimalist aesthetic of the watch. Alligator represents the most elegant option for formal occasions, whilst a NATO in heavyweight cotton offers daily versatility without compromising the character of the model.

Strap replacement requires a specialised tool (spring bar tool). Position the tool under the metal lug pin on the underside of the case, apply gentle pressure to compress the internal spring, then extract the pin. Repeat on the opposite side. To install the new strap, insert the pin into the lug holes, ensuring the spring is fully compressed before release.

Yes, any strap with a 22-millimetre lug width is compatible with the D. Dornblüth & Sohn 99.2 (07) ST. Milano Straps offer certified artisanal quality and perfect fit for this exact specification.

A vegetable-tanned leather strap, subject to ordinary maintenance (gentle cleaning and annual conditioning), has a useful life of 3–5 years under regular daily wear. Firenze leather, vegetable-tanned, develops a distinctive patina that extends its aesthetic appeal even with natural wear. Shell cordovan, by virtue of superior structural density, may exceed 7 years of service.
