Hi Tony. Congratulations on reaching a life phase when are in the “spending” rather than the “saving” phase of life. I hope you enjoy yourself and time with the family.
Personally, I would hesitate to sell any watches until I’ve sorted out any major lifestyle changes. You may find the “cheaper” watches suit you more than others. I would question why you want to sell as well (just my opinion).
But looking at that set and having to sell - I’d keep the Omega PO sell the rest.
