For reference, there’s a very popular variant of the Speedmaster Professional that uses a sapphire crystal rather than a hesalite (basically plastic) crystal. Despite never having been used in space (since the shattering crystal is a risk) the sapphire model is still considered a “professional” edition and highly sought after. People who wear it enjoy the aesthetic of the spacefaring version with the earthly practicality of scratch-proof sapphire. The Swatch version’s desirability is just the same logic a taken a few more steps. It’s made by Omega, has the same basic design, and evokes the imagery of the space race.
Alternatively, consider the popularity of the Tesla toy car for kids. It’s not anything like the real Tesla in terms of functionality but is still a cool electric vehicle, especially if you already have a Tesla.
