Are you looking for new, used, vintage, specific model? What region of planet do you live? There are a number a very trustworthy and professional sellers around these forums and can be recommended. Any further specifics you can provide to assist us in pointing you in the right direction?
Thanks! Yes: I live in New York, looking for a second hand Omega Seamaster Planet Ocean. Any reliable vendor recommendations would be greatly appreciated. And - do you think it's possible to find one of these in good condition for under $2800?
Yes, Jomashop is fine. I suggest you send a PM to @Kringkily here on the forum. He is NYC based and has or can get just about anything you need. Fair prices and a great guy. I have purchased WAY too many Omegas from him.
@WatchVaultNYC would be another excellent option as well as the fore mentioned @Kringkily. Many's experiences with Jomashop have been okay, mine was garbage and wouldn't personally use them again. Especially knowing now there's so many other great sellers around here. Good luck and happy hunting!
$2800 for a planet ocean will be difficult to find. Your probably looking more at $3000-$3500 give or take. Just from what I see on most forum sites.
