Frequently asked questions

What is the lug width of the D. Dornblueth & Sohn 99.2 (01) ST?

The D. Dornblueth & Sohn 99.2 (01) ST features a lug width of 22mm. This measurement is essential for selecting compatible straps and is determined by the internal spacing between the two pins anchoring the strap to the case.

Which strap is recommended for the D. Dornblueth & Sohn 99.2 (01) ST?

For this model, a vegetable-tanned leather strap represents the most aesthetically coherent choice with the watch's artisanal character. Calf or cowhide leather in dark brown amplifies the sobriety of the satin-brushed case. For more intensive use, FKM rubber offers practicality without visual compromise. NATO and canvas are suitable for informal contexts.

How do I change the strap on the D. Dornblueth & Sohn 99.2 (01) ST?

The strap is replaced by loosening the screws anchoring the pins to the case lugs. Use a precision tool (watchmaker's screwdriver or dedicated lever) to avoid damaging the brushed finish. Once the pins are removed, the old strap detaches. Insert the new strap, ensure proper alignment of the holes, and fasten the screws with gradual, uniform pressure.

Which aftermarket straps are compatible with the 99.2 (01) ST?

Any strap with a 22mm lug width is compatible with the D. Dornblueth & Sohn 99.2 (01) ST. Available in leather (cowhide, calf, alligator), rubber, NATO, canvas and various textiles. Always verify that the strap features holes sized for the watch's standard pins.

How long does a leather strap last on a daily-worn timepiece?

The lifespan of a leather strap depends on the quality of tanning, the type of leather, and the intensity of use. A vegetable-tanned leather strap, with proper care (avoiding prolonged moisture exposure), typically lasts 3-5 years in daily use. A natural patina develops progressively, narrating the history of wear. More robust hides (vegetable-tanned cowhide) offer greater longevity.
