Damasko
Three-hand Models DA20— lug 20mm

The lug width of the Damasko DA20 is 20mm. This measurement represents the distance between the two lugs on the case where the strap attaches. It is essential to verify that your chosen strap measures exactly 20mm in width to ensure a precise and secure fit, avoiding lateral movement.

For the DA20, a strap in alligator or calf leather with vegetable tanning represents the finest choice, as it reinforces the watch's instrumental philosophy. Colours such as dark tobacco brown, absolute black, or deep burgundy integrate harmoniously with the 40mm satin case. For intensive use, a natural rubber strap or a heavy canvas NATO fabric strap are both functional and elegant alternatives.

To change the strap, you must remove the spring bars connecting the strap to the case lugs. Use a dedicated spring bar tool or consult a watchmaker. Position the tool tip into the small slot on the spring bar, apply gentle pressure to release the internal spring, and withdraw the old strap. Insert the new strap by threading the spring bars into their designated slots, ensuring the spring snaps back into position.

Absolutely. Any 20mm-width strap is compatible with the DA20. Quality aftermarket straps often offer greater variety in materials, colours, and finishes compared to original manufacturer offerings. Verify that the strap width measures between 19.8 and 20.2mm at the case contact point to ensure precise compatibility.

A quality vegetable-tanned leather strap on a daily-wear watch like the DA20 typically lasts 3 to 5 years, depending on frequency of use, water exposure, and climate conditions. The ageing of leather is not a defect but part of its natural evolution: it develops patina, colours shift, and texture transforms. Minimal maintenance—periodic cleaning and occasional conditioning—significantly extends longevity, transforming the strap into a tangible chronicle of elapsed time.
