I think you either need to buy it or pick a watch, but wait months before buying. It might help to see it in person. You don’t need one of every type of one of every dial color. So get your favorite type in your favorite dial color. Think about what works for you, rather you working for it. I learned quickly that I don’t like mechanical watches. Erring on the smaller size is better looking and more comfortable as the watch slides around on the wrist, for example.
