Frequently asked questions
What is the lug width of the D. Dornblueth & Sohn 99.1 (1) ST?
The lug width of the D. Dornblueth & Sohn 99.1 (1) ST is 22mm. This measurement indicates the internal space between the watch's lugs and is essential for selecting a compatible strap. You can verify this by extracting the spring bar using a dedicated tool (pin remover) and measuring the internal gap. Any strap specified as 22mm will fit perfectly on this model.
Which strap is best for the D. Dornblueth & Sohn 99.1 (1) ST?
There is no absolute 'best,' but rather choices based on intended use. For formal elegance and daily versatility: vegetable-tanned calf leather in havana or black. For maximum aesthetic sophistication: alligator in black or cognac. For practicality and warm climates: nylon NATO in navy blue or anthracite grey. For intensive use and water resistance: vulcanised rubber with deployante clasp. The aesthetic sobriety of the 99.1 (1) ST pairs best with straps that complement rather than compete visually with the watch.
How do you change the strap on a watch with 22mm lugs?
The procedure is straightforward and requires a pin remover (a dedicated tool that extracts the spring bar) or alternatively a small flathead screwdriver. Position the watch on a soft cloth to prevent scratches. Locate the small steel pin that runs through the lugs on one side. Use the pin remover to extract the pin with a firm but controlled motion. Remove the old strap. Insert the new strap by aligning the holes with the lug, then reintroduce the pin from the opposite side until it is fully seated. If you lack the tool, consult a watchmaker: the cost is minimal and guarantees no damage to the case.
Are aftermarket straps compatible with the D. Dornblueth & Sohn 99.1 (1) ST?
Yes, all straps specified for 22mm lug width are compatible with the 99.1 (1) ST. This means you can choose from dozens of material, colour, and style options: leather from various tanneries, NATO, rubber, shell cordovan, and alligator. Always verify that the strap you purchase is explicitly marked as '22mm lug width' or similar. Many specialised suppliers also offer custom 22mm straps, allowing you to personalise your watch completely and create combinations that reflect your personal aesthetic and use case.
How long does a leather strap last on a watch like the D. Dornblueth & Sohn 99.1 (1) ST?
Durability depends on material and usage patterns. A vegetable-tanned calf leather strap, with minimal maintenance (avoiding prolonged immersion, drying after rain), lasts 5–8 years in daily wear. Alligator and shell cordovan easily exceed 10–15 years due to the superior density of the leather. A nylon NATO strap in ballistic fabric is practically indefinite, though colour may fade after years of sun exposure. Vulcanised rubber lasts 8–12 years before elasticity diminishes. Recommendation: rotate between at least two straps (if possible) to distribute wear and extend the life of both. A worn strap need not be discarded: it can be resealed by a leather specialist or transformed into smaller accessories.
