Strap for Saxonia Automatik Yellow Gold - Diamond / MOP

The lug width of the A. Lange & Söhne Saxonia 840.021 is 19 millimetres. This dimension represents the horizontal space between the two lugs of the case, where the watch strap attaches. To verify strap compatibility, measure the internal space between the lugs using a digital caliper: if the reading falls between 18.8 and 19.2mm, the strap will fit with proper constructive tolerance.

For the 840.021 in 18-carat yellow gold, we recommend straps in alligator leather with vegetable tanning, in black or dark brown tones: the grain texture of alligator complements the watchmaking craftsmanship of the case without competing visually. Alternatively, cognac or hazelnut vegetable-tanned calf leather offers a softer tactile feel and develops noble patina through ageing. For those who appreciate brilliance, cordovan bordeaux transforms under light, shifting from reddish-brown to nocturnal violet. Avoid saturated colours that contradict Glashütte's minimalist language.

To change the strap, use a quality spring bar tool: insert the tip into the lateral slot of the lug spring, apply gentle pressure to compress the spring towards the case centre, and slide the lug itself out of the aperture. Repeat for the opposite lug. Insert the new strap by aligning it perpendicularly to the lug space, and allow the spring to re-engage naturally. Verify that both lugs are perfectly seated before wearing the watch. If you are inexperienced, consult a professional watchmaker.

Yes, all straps with a 19mm lug width are compatible with the 840.021. MilanoStraps offers a curated selection of artisanal 19mm straps crafted from premium leather (alligator, calf, cordovan) with vegetable tanning and high-level constructive finishing. You can choose from standard models available online or commission a bespoke strap at the Casati Milano atelier, where you personalise every aspect of the craftsmanship.

A premium leather strap (alligator, calf, cordovan) with vegetable tanning, subjected to daily wear and appropriate maintenance, maintains structural integrity between 2 and 4 years. Durability depends on intensity of use, exposure to moisture, and preservative treatment. MilanoStraps supplies all straps with an 18-month warranty against manufacturing defects. To extend service life, avoid prolonged exposure to salt water, store in a dry environment, and condition the leather with specific natural oils if necessary. Cordovan tends to last longer than other leathers due to structural density.
