Hi Hans - what a beauty! If this were mine, I'd not be bothered with such trifling details as the crudeness of the engraving.
Also the MH bezel - remember it was likely possible to choose at the time, and though most Viceroys have the tachy one, MH ones are not uncommon.
It's a wonderful watch, rarely do we see any with so white subdials - and with all the paraphernalia you have. Wear it well and in good health.
Cheers,
Fabrizio
