“Wearable” is an adjective that we throw around a lot. It might not have a codified definition, but it represents a combination of comfort, functionality and versatility.
As silly as it sounds, the easiest way to think about it is that the more wearable a watch is, the more you want to wear it.

For example, the Concorde Titanium from Pequigent maximizes wearability through its size, weight and appearance. The 36mm case, integrated solid-link bracelet and dial plate are all made from titanium, creating a refined, uniform appearance and minimal impact on the wrist.
The Concorde is one of the French watchmaker‘s marquee designs, but it has previously only been produced in steel. It is a smoothed-off take on a 1970s-style integrated sports watch, with a cushion case and rounded bezel.

Because of its shape, the 36mm case size leaves a slightly larger visual impression on the wrist, but being made primarily of Grade 5 titanium, it weighs only 84 grams.
The Concorde Titanium represents the prevailing trend in watchmaking toward smaller cases that are more comfortable and practical for daily wear, and doubles down by cutting weight as well.
