Ah ok, I thought you meant that those brands are high demand (as in the only real high demand brands on the planet).
I misunderstood.
But yeah I reckon they're golden times to now trade in top tier steel sportswatches (mens models).
Submariner, daytona are now probably the best investments you can make, not even limited to watches but also regarding stock etc (or at least could have made 5 years ago, but thats hindsight), not to speak of the vintage ones
