Depends on why you are getting it. If it is for your own enjoyment then set a target price and simply find the one you like the most.
If it is to impress women then you have to buy something that will fit your unique style. For example Daniel Craig’s
Omega fits his style but it may be completely wrong for you.
Now if you don’t have your own unique style then you can buy any watch you feel like since it won’t make any difference to women either way. Someone commented that women notice wedding rings, watches and shoes. This is only partially correct. You can have the best shoes in the world but if they don’t fit in with your style she will be completely turned off.
