Frequently asked questions

What is the lug width of the Damasko DA373.black?

The lug width of the Damasko DA373.black is 22 millimetres. This measurement is taken between the spring bars that connect the strap to the case at 12 and 6 o'clock. All compatible straps must have exactly 22mm lug width to fit correctly.

What is the best strap for the Damasko DA373.black?

There is no single 'best' option, but choices that reflect usage patterns. For formal contexts, vegetable-tanned Tuscan leather in black with contrasting stitching. For robust professional environments, grey-charcoal NATO in polyamide. For aquatic or marine applications, vulcanised silicone in black or deep blue. Selection depends on the operational mission you assign to the watch.

How do you change the strap on a DA373.black?

Strap change involves removing the spring bars from the case lugs. Use a spring bar tool – a small flattened instrument – to compress the bar on one side, reducing its diameter, and slide it out from the housing. Repeat on the other side. Insert the new strap by aligning the holes, reintroduce the bars, and ensure they click fully into the lugs. Operation takes less than two minutes once technique is mastered.

Does the DA373.black accept aftermarket 22mm straps?

Yes, completely. Since 22mm is a standardised measurement, the DA373.black is compatible with any artisanal strap designed for 22mm lug width, regardless of manufacturer or material. Leather, alligator, NATO, rubber, shell cordovan – if they declare 22mm, they will fit perfectly. Consult our dedicated 22mm strap catalogue to discover available options.

How long does a leather strap last on a Damasko DA373.black?

A vegetable-tanned leather strap, worn daily, maintains structural and aesthetic integrity for 18-36 months. Patina and signs of use increase appeal, they do not compromise the strap. Alligator, being denser and more fibrous, extends durability to 36-48 months. Longevity depends on frequency of wear, ambient humidity, and maintenance – regular cleaning with a damp cloth and air drying. Replacing the strap requires no watchmaker intervention; it is recommended periodic maintenance.
