Strap for 99.2

The lug width of the D. Dornblueth & Sohn 99.2 (7) RG is 22mm. This dimension defines the strap attachment between the lugs. To verify correctly, measure with a calliper the internal distance between the two spring bars, not the external width of the case. Accurate measurement ensures complete compatibility with aftermarket straps.

For the 99.2 (7) RG in rose gold, we recommend full-grain leather straps with vegetable tanning (dark brown, cognac, black) or shell cordovan, which create aesthetic continuity with the case. Quality alternatives: alligator for formal contexts, heavy canvas NATO for versatile daily use. The 42mm diameter with 22mm lug width accommodates straps of 3-4mm thickness without creating excessive bulk.

Position the watch on a stable support. Use a rounded-tip tool (spring bar tool or dedicated extractor) to gently press inward on the spring mechanism securing the strap to the lug. Once released on one side, slide the spring bar completely through. Repeat on the other side. Insert the new strap by aligning the holes and reinsert the spring bar with a smooth sliding motion until the spring locks into place. Verify that the strap sits symmetrically against the case.

All straps with a 22mm lug width are compatible. On milanostraps.it the 22mm collection includes Italian leather, shell cordovan, alligator, NATO and technical rubber. Verify that strap thickness (typically 3-4.5mm) does not create excessive tension on the lugs. Higher quality straps maintain aesthetic value and durability over time, particularly vegetable-tanned leather that develops natural patina.

A high-quality full-grain leather strap (vegetable-tanned or shell cordovan) worn daily lasts 3-5 years before showing signs of structural wear. Durability depends on: frequency of use, moisture exposure, protective treatments applied. NATO and technical rubber straps have superior durability (5-7 years). Vegetable-tanned leather, whilst ageing visually, remains functional longer because the fibre maintains natural elasticity. To extend lifespan: avoid prolonged immersion, treat periodically with specific wax or conditioner, rotate with other straps to reduce concentrated wear.
