Omega, IWC, GO all in the same breath as deBethune?
James, you already have a very impressive and esoteric collection.
I think you'd be diluting it with any of the Omega/IWC/GO choice.
You should not worry abt the deBethune servicing.
Whichever watch you own, you still need to send it back to the manufacture e.g. your HW?
That's just my opinion…..
good luck and if its the deBethune, I'd love to see it in the metal…. the others? not so much as I can see those anywhere, anytime and on most people's wrists…incl. my own as I have watches from all those 3 brands..good solid brands no doubt but lacking the panache of the deBethune…or best said by the French…je ne sai quoi
For your 40th milestone watch it has to be something really special…
You can get a Omega/IWC/GO for those other lesser occasions….
