I think the Khaki Field Murph is a good example. I can see a person who is just getting into watches buying the Murph as their first nice watch. I can also see someone who's been several years into watches adding the Murph to their five- or ten-watch collection.
I don't feel like the same can be said for, say, a Tissot Gentleman, although it's a great watch no doubt.
This is probably very subjective. You may disagree with the examples I gave. But I hope you get what I mean. What is your example of a such watch?
Another way to put it: What do you wish you have bought as your first watch (or early in your hobby journey), knowing what you know now about watches, about your taste, and so on?
The Seiko 5 Rowing Blazers edition is really cool.
