Strap for 99.1

The lug width of the D. Dornblueth & Sohn 99.1 (02) RG is precisely 22 millimetres. This specification determines the strap width required for proper fitment on the spring bars. Measurement should be taken perpendicularly between the inner diameter of the lugs using a digital calliper or rigid ruler to ensure accuracy.

We recommend vegetable-tanned alligator in cognac or bordeaux tones, which complements the warmth of the rose gold case. Shell cordovan in vitello offers elegant versatility with natural patination over time. For daily wear, a quality linen NATO maintains sophistication whilst providing practical durability. FKM rubber with fine texture finish permits seamless sport-to-formal transitions.

Position the watch on a soft mat. Using a spring bar tool, gently compress the small spring bar beneath the lug pin. Apply steady pressure towards the case centre, then extract the pin by sliding away the current strap. Repeat on the opposite side. Align the new strap's holes with the lugs and press the pin until it clicks into place securely.

Yes, entirely. The standard 22mm lug width accommodates any high-quality aftermarket strap. Milano Straps curates a collection of 22mm artisanal straps in fine leathers, technical fabrics, and specialist rubbers, each tested for perfect fitment on the 99.1's lugs without play or friction.

A premium leather strap (alligator, cordovan, fine vitello) typically endures 3–5 years with daily wear and proper care. Longevity depends upon exposure to moisture, perspiration, and ultraviolet radiation. Vegetable-tanned leather matures more nobly than synthetic treatments, developing characteristic patina. Rotating two to three straps seasonally substantially extends each strap's service life.
