Frequently asked questions

What is the lug width of the D. Dornblueth & Sohn 99.1 (6) RG?

The lug width is 22mm. This measurement represents the thickness of the compatible strap and ensures a perfect fit without slipping or forcing. When ordering a strap for the 99.1 (6) RG, ensure that specifications clearly indicate 22mm.

Which strap is recommended for the D. Dornblueth & Sohn 99.1 (6) RG?

For the 99.1 (6) RG in rose gold, genuine nilotius alligator with fine grain texture offers the finest aesthetic dialogue. Vegetable-tanned leather represents an excellent alternative for those who appreciate patina evolving over time. A heavy cotton NATO or fluoroelastomer rubber allow seasonal versatility whilst maintaining architectural elegance.

How do you change the strap on a watch with 22mm lugs?

Strap replacement requires a spring bar removal tool to depress the elastic pins beneath the lugs. Position the tool in the dedicated groove of the pin, gently lift whilst extracting the strap. Insert the new strap by aligning the holes to the lugs and press until the locking click. This operation is recommended at a professional watchmaker to avoid damage to the case.

Is the strap compatible with other watches besides the 99.1 (6) RG?

Yes, any 22mm strap is compatible with all watches featuring 22mm lugs. Simply verify the measurement specified in your watch manual or measure directly between the suspension pins. Compatibility is universal within the same lug width.

What is the average lifespan of a leather strap?

A quality leather strap, whether vegetable-tanned or genuine alligator, typically lasts between 3 and 7 years depending on usage, sun exposure, and wearing frequency. Daily wear accelerates ageing; occasional use extends longevity considerably. The patina that develops is acquired character, not wear. A heavy cotton NATO strap typically lasts 5–10 years due to simple construction.
