As for watches, I have a Citizen eco-drive chronometer; I've owned it for over 3 years, the crystal glass face has not got a single scratch on it despite me wearing it each day for work. It's solar powered so doesn't need the battery changing and it connects to the atomic clock in the early hours of each morning to set the time, so it's never more than a second out, and it automatically adjusts when the hour goes back or forward and sorts the date out each month, even during a leap year.
It should have been £400 but I shopped around and paid £299 for it brand new and boxed, and I think it's been worth every penny of that to me, even if it broke tomorrow. To put that in perspective, could you even get a Rolex Oyster or Omega Seamaster serviced at an authorised dealers for £299? Also, how accurate is your Omega, Rolex, Tag Heuer, Patek Philippe, etc? I have a friend who likes and owns some 'premium brand' watches and he tells me it's not about the accuracy... but it should be really, shouldn't it... after all, what use is a watch unless it tells the right time? It would be better off as a non runner, wouldn't it... at least it would be spot on twice a day then!
Each to their own, if I was a multi millionaire then I'd probably buy a Rolex Oyster Perpetual Day Date for 'best'. However, if what's been said here is correct,
I doubt it would be a new one from an authorised dealer, as I never pay full asking price for any premium product, and I don't intend to break the habit of a lifetime for a watch, no matter how pretty and sparkly it might be.
