Strap for 99.1

The D. Dornblüth & Sohn 99.1 (05) ST features a 22mm lug width. This measurement is the optimal calibre for a 42mm case diameter, ensuring balanced proportions and stable wrist wear. Lug width is the internal distance between the two spring bar pins that connect the strap to the watch case.

For this Saxon timepiece, we recommend a black or dark brown alligator strap with vegetable tanning for formal elegance; Italian calf leather for those who appreciate organic patina development over time; a navy blue NATO strap to maintain the sporty character whilst respecting the technical heritage; an FKM rubber strap for those alternating between office and outdoor activities. Your choice depends on context of use and personal colour preferences.

The process is straightforward: obtain a spring bar tool (lever with rounded tip) or consult a watchmaker. Insert the tool tip into the lower hole of the lug spring, press gently to release the pin and remove the old strap. Repeat on the other end. Insert the new 22mm strap, aligning the holes, then lower the spring until you hear a secure click. Verify that the strap is firmly secured before wearing the watch.

Yes, absolutely. The 22mm lug width of the 99.1 (05) ST is compatible with all straps featuring a 22mm lug width, regardless of brand or material. You can choose from leather (alligator, calf, shell cordovan), fabric (NATO, Cordura), rubber and other artisanal solutions. Always verify that the width is precisely 22mm to guarantee correct fit.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years with daily wear, depending on frequency of use, climate and care. Natural leather develops patina over time, acquiring character and visual depth. To extend strap life, avoid prolonged moisture exposure, occasionally apply specialist watch leather balm and alternate with other straps. Proper maintenance can extend durability to 7-8 years.
