I can't speak for Omega and how they decide these things. I can tell you I bought a lot of watches last year from the boutique (a couple I haven't mentioned on the forum). I've brought in some friends who have also purchased watches, which doesn't hurt, I suppose. I have forged relationships with my local boutique to the point I consider them my personal friends. I have met many of the other local clients, some of whom I am friends with now. I'm sure it doesn't hurt to be an honest to goodness Omega fanatic, and to be active on social media and with other clients (we are more valuable than a whole department of marketing people). The perks are nice, I won't lie, Omega really has some amazing events, but I wouldn't have done anything different had I received none - I love my Omega watches, and I love my local boutique.
My advice, buy more watches 馃榿
