Suggestion for my collection

Hi everyone, I recently started getting into the world of watches, and I’m expanding my small collection.

At the moment I own:

∙	Hamilton Khaki Field Murph 38

∙	Tissot Le Locle

∙	Festina Swiss Made F20016/1

∙	Sea-Gull 1963 International Edition

At this point I’d like to introduce something more “prestigious” and I’m very undecided between two great desires: the Omega Moonwatch and the Tudor Black Bay One 41.

Which one would you choose? Regarding the price, I’d also consider the second-hand market, so more or less they’re close (even though the Tudor costs less)
