I would wait a bit and see if the watch still speaks to you after trying it a few times. One of the thing I realised (at least for me) is that watches infatuation is a thing. So you might love it very intensively but then, with time, you realise that some things might not be right, Winding, etc. Since you want a tourbillon in your collection you should go for something that you enjoy and can easily service long term. I would also about the warranty (e.g. 5 years with GP, is it just 2 years with MB ? If that is the case take that into account as 2 years run out very quickly in a watch rotation) and servicing costs/timing. Price would also be an important consideration I would just take as much time as you can to be 99% sure that this is the right watch for you e.g. that you will wear it and find it superior, from YOUR standpoint, to other options.
