Strap for 99.1

The lug width of the D. Dornblueth & Sohn 99.1 (07) RG is 22mm, measured as the internal distance between the case lugs. Measure this distance with precision millimetre accuracy before ordering a compatible strap, as even 1mm variance compromises mechanical fit and security of the strap.

An alligator strap in cognac or dark brown enhances the luminosity of rose gold without visual competition. Alternatively, shell cordovan offers colour evolution over time parallel to the natural patina of the case. For daily versatility, a vegetable-tanned calf strap or robust NATO guarantees practicality whilst maintaining formal elegance.

Strap replacement requires specific tools: a strap removal tool or small flat lever to extract the spring bars without marking the rose gold case. Proceed carefully, supporting the watch on a soft surface. If inexperienced, contact the Casati Milano atelier for professional strap change ensuring zero risk to your case.

Yes, any strap with 22mm lug width is mechanically compatible. However, artisanal straps of superior quality are recommended to respect the noble materials of the rose gold case. Always verify that strap thickness (3.5-4.5mm) creates no friction within the case lugs.

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts typically 3-5 years with daily use, developing natural patina and personal character. Lifespan depends on frequency of use, sweat exposure, humidity and tanning quality. A 2-piece NATO fabric strap resists 5-7 years. Periodic maintenance and drying significantly extend useful life.
