I have to agree with this. The sentiment of some people in this thread (as it reads to me) like they feel they are walking on hallowed ground in a boutique and need to tread carefully is patently ridiculous.
If one owns a luxury watch like an Omega, let alone a special and modern one like a recent LE, and they wish to sell it to a buyer who wishes to collect because they might be concerned for its condition or legitimacy, what better place is there to do it for everyone's comfort than inside a boutique? Why should one visit under the pretence that they are here with their friend or life partner to look around? Why should the store staff be unhappy at all, assisting known patrons of their brand; the two people in the shop are known owners or soon to be owners, whereas the other 80% coming in are window shoppers. This is part of their job description. What is all this pretentious bullshit?
I'm sure I am not the only one on this forum who has sold watches inside an AD or a boutique before, but personally I've been treated exceptionally every single time I have done so. Knowing the employees in the boutique so they are more liable to 'give permission' has nothing to do with it. I've been inside boutiques which I've never stepped in before, because often the location is dictated by the buyer's meeting preference, especially when one travels a lot like I do. I have been treated well every time and it would negatively affect my perception of the brand if I was not.
Besides, it is not like this must happen every day surely? More often than not more recent watches are sent in the post, or have been serviced and come with documentation confirming this. It's not like this is some endemic of shady people intermixed with genuine collectors coming in off the street to hawk their wares that the boutique is trying to deal with in their policy. If it's store policy, they should have asked you to leave and it sounds like they did not do this for whatever reason. If so, this is down to poor training and bad management if you ask me.
Also Omega and most brands carry out checks with the timegrapher and pressure testing machine as the norm for owners who walk into their boutiques, irrespective of context, and even for watches that are not in warranty. As relates to a failed pressure test, this isn't as big of a deal as one might think. A watch that has spent its life in a cardboard box can fail a pressure test after a few years. What is most important from any checks carries out is the visual inspection of the movement by the watchmaker and the timekeeping.
Which boutique was this by the way? Did the seller look shady or something?
