QUICK ANSWER
A breathable, woven nylon mesh strap with a continuous weave that allows the buckle to fasten at any position along its length.
A Perlon strap is a woven mesh strap made from Perlon — a synthetic polyamide fibre similar to nylon — constructed as a continuous single-layer weave rather than a solid flat band. The result is a strap with no fixed holes; the pin of a standard tang buckle can be inserted through the weave at any point along the strap's length, allowing an infinitely adjustable fit. This is particularly useful in warm weather or during exercise, when wrist size fluctuates slightly.
Perlon straps originated in Germany in the post-war period and became closely associated with German and Eastern European watchmaking culture. They are lightweight, dry quickly after contact with water, and breathe well against the skin — practical qualities that made them popular as everyday and sport straps before rubber and silicone alternatives existed. Their association with vintage German watches, Flieger watches in particular, has kept them in continuous production and given them a nostalgic credibility that synthetic straps with more recent origins lack.
Contemporary Perlon straps are produced in a wide range of colours and weave patterns. Single-pass designs are the most common, using a single piece of woven material that passes through the buckle bar. They pair particularly well with vintage-influenced watches, field watches, and pilot watches, though their casual character makes them less suitable for formal or dress contexts.

Unlike a leather or rubber strap, which has fixed holes, a Perlon strap is adjusted by threading the buckle pin through the weave at whatever position gives the desired fit. Simply thread the strap as you would any tang buckle strap, then insert the pin through the mesh rather than into a drilled hole. Trim any excess length if needed.
Reasonably so, though they are not the most durable strap option. The woven structure can fray over time, particularly at the cut ends, and the material holds odours more readily than rubber or leather. Most Perlon straps are inexpensive enough that replacement is straightforward.
Perlon straps suit vintage-influenced watches, Flieger and field watches, and casual everyday pieces particularly well. They are strongly associated with German watch culture and pair naturally with watches from Nomos, Laco, Stowa, and similar brands. They are generally considered too casual for formal dress watches.
