The differences with bicycles and cars is that lighter weight is a feature (all else equal, it helps you go faster, and in the case of cars, use less fuel). With watches, the extra heft is insignificant in the grand scheme of things, but adds a premium "feel" since aluminum is more easily dented.
Who decided heavy = Premium ?
Genuinely interested, as this must hard back to something very very old.
If you had babies, never told them anything about this type of thing, I don't feel they would be mentally able to decide that a heavier item was in some way better.
There is just as much chance that they would think. Well, I have to strap this to my body, carry it around all the time, so lighter and more unnoticeable would be better (more premium)
I am guessing, but I can only think this harks back to very old industrial revolution mentality, when things were made from metal and durability was king, and metal cost a lot of money.
If something was heavier, this much mean it used more metal, and more metal meant stronger, lasted longer, so weight was associated with a higher quality.
If it was lighter, as they did not have any modern materials back then, even aluminium, light meant it was made from thin materials, so was going to be weaker, less durable, and hence cheaper.
Heavy = premium quality = expensive.
Light = lesser quality = cheap.
We of course, know better now, and have a vast array of materials, and ways to use those materials in newer ways.
This is all a guess, but I wonder if that is where this concept started.
Of course, this means nothing now. You can make something cheap and heavy, or expensive and light.
Many still have this thing from the past stuck in their brains, passed on my generations.
To the point where people actually stick a lump of metal into something modern and light to make it heavier, simply so it feels better quality.
Humans are very slow animals to change
