This is the Speedmaster Moonphase I bought around 2005/2006 for USD2,050. It is a brand new parallel goods from a reputable grey dealer in my area, thus it doesn't have the dealer stamp on the warranty card. With the reliable Lemania movement, there is really nothing to worry about it, and besides nothing has happened during the warranty period if I was to purchase it from there for USD4,600. This particular cream dial model has already been discontinued.

I have not worn this watch for quick some time, it is sitting in the case. Here is my question, would you sell it (and I mean not for gain purpose but simply offlord it if I am not wearing at all)? I don't need the money and I don't have anything in mind that I would like to buy thus in need for watch money. What would you do? Moreover, Omega experts, what do you see for this watch down the road in say 5-10 years; would it become a classic (yes, I have a 7 years old boy and 3.5 years old girl and my watches will go to them whether they will like / treasure it or not)?
Once again, thank you very much for reading, and I look forwrad to your valuable advice / opinion.
