Strap for Datograph Platinum / Black

The lug width of the Saxonia 403.035 is 20 mm. This measurement should be taken internally between the spring bar posts using a digital calliper, positioning it at the inner shoulder of the case. Precise measurement is essential to ensure the strap fits perfectly on the case without play or binding.

For the platinum Saxonia 403.035, black alligator is the most coherent choice: the natural texture of the leather dialogues elegantly with the satin-finished brilliance of the case. Alternatively, vegetable-tanned calf offers a finer grain surface with veining that develops over time, or burgundy shell cordovan for those who appreciate tonal complexity and natural mirror patina.

Changing the strap on the Saxonia 403.035 requires removal of the spring bars that retained the previous strap. Use a dedicated spring bar tool to compress the pin and slide it out of the lug. Next, insert the new strap by aligning the internal holes at the ends of the spring bar, then snap it into place until you feel the security click. A tolerance of 0.3 mm on the lug width is still acceptable; greater tolerances require specialist intervention.

Yes, any strap with a 20 mm lug width is compatible with the Saxonia 403.035, provided it meets high construction standards. Specialist makers of artisanal straps guarantee precise tolerances, finishes coherent with the watch's character, and the use of noble leathers. The choice of material (alligator, calf, shell cordovan) should reflect the Saxonia's classicist philosophy and the quality of the case finishing.

A high-quality leather strap, made from noble leathers and vegetable-tanned, typically lasts 3 to 7 years depending on usage, climate, sun exposure, and wearing frequency. Natural leather gradually wears, developing patina and micro-cracks; a well-maintained strap can continue functioning aesthetically and technically beyond 7 years. Warranty on manufacturing defects typically covers the first 18 months; thereafter, wear is a natural attribute of organic material.
