Strap for Saxonia Big Date Platinum / Black

The A. Lange & Söhne Saxonia 105.035 features a lug width of 18 millimetres. This dimension is specific to the 33.90 mm case and maintains the elegant, restrained proportions of the model. To verify strap compatibility, measure the distance between the lugs at the spring bar seat, excluding the spring bar body itself.

For the platinum Saxonia 105.035, an alligator or vegetable-tanned shell cordovan strap is recommended. Alligator in cognac or toasted brown tones creates visual continuity with the platinum case, whilst cordovan develops extraordinary depth as it ages. Avoid rubber or fabric straps, which lack the material dignity appropriate to this timepiece.

Strap replacement is performed by removing the spring bar connecting the lug to the strap. Use a dedicated spring bar tool to gently compress the spring and slide the bar out of the lugs. Insert the new 18 mm strap, ensuring the spring bar clicks firmly into position. If unfamiliar with this procedure, entrust the task to a specialist service.

Yes, any strap with an 18 mm lug width is compatible with the Saxonia 105.035. We recommend selecting straps from specialist artisans who employ premium materials (alligator, cordovan, vegetable-tanned calf) rather than industrial alternatives. Compatibility is determined by lug width, not brand.

Durability depends on material and usage patterns. An alligator or vegetable-tanned cordovan strap, worn daily, typically lasts 5–8 years before functional replacement becomes necessary (buckle wear or leather deterioration). Vegetable-tanned calf offers similar longevity. With regular maintenance (gentle cleaning, periodic conditioning), the strap extends its service life and develops an aesthetically beneficial patina over time.
