Frequently asked questions

What is the lug width of the D. Dornblueth & Sohn 99.1 (06) ST?

The lug width of the D. Dornblueth & Sohn 99.1 (06) ST is 22mm. This measurement represents the distance between the two spring bar pins protruding from the case at 12 o'clock and 6 o'clock positions. Any strap compatible with 22mm lug width will fit perfectly into the case lugs, ensuring a secure fit without lateral play.

What strap is most recommended for this model?

For the 99.1 (06) ST, we recommend an alligator strap with vegetable tanning or shell cordovan. Both enhance the minimalist Saxon aesthetic: alligator provides organic texture, whilst shell cordovan offers superior grip. For intensive daily wear, structured calf leather in medium grain represents the most versatile solution.

How do I change the strap on this watch?

Strap replacement requires a dedicated tool (spring bar tool). Position the watch on a stable surface, insert the thin tip of the tool into the hole beside the spring bar pin, push gently inward to release the pin from its housing. The pin will slide out of the case. Repeat for the second pin and insert the new strap in reverse. This operation is suitable for those with manual dexterity; we recommend contacting an official service centre for precious watches.

Can I use an aftermarket strap compatible with 22mm lug width?

Yes, any strap designed for 22mm lug width is compatible with the D. Dornblueth & Sohn 99.1 (06) ST. Milanostraps artisanal straps are crafted from vegetable-tanned leather, structured calf, alligator and technical materials, all available in 22mm size. Superior artisanal construction quality guarantees comfort and durability exceeding industrial products.

How long does a leather strap last on this watch?

A vegetable-tanned leather strap lasts 3-5 years under moderate daily use (4-5 days weekly). Vegetable tanning develops a natural patina that progressively darkens, improving aesthetics. Wear accelerates with exposure to perspiration, humidity and direct sunlight. Shell cordovan straps last up to 7 years owing to superior leather density. Rotating between multiple straps significantly extends useful life.
