If you like it, keep it, it's that simple. Is there anything nicer or more interesting for what's it's worth? Very possibly not, the 'Great White' Seamaster is a very cool piece and quite rare.

If you've had it a while you may even have made some money but it's probably not an investement piece. Although who knows!

I'd love one - currently don't have a modern Omega, this might do it...
