Help with 15300 Bracelet

[Rumpolejim]

hi all

I recently acquired a 15300. Everything seems ok to me but the only thing that has thrown me a little is this engraving on the bracelet that looks like a MN but very very round font and a rather odd looking “Swiss Made” next to the clasp.

Are these normal markings on the bracelet or should I be worried?

I have a 15300 H-series (2010 or thereabouts i believe) and it also has the cursive”MN”. I have asked the AP House sales team in passing and they were unsure either.

I know Maspoli SA makes the current bracelet for the Royal Oak, but they didn't start until 2012. Before then, Werthanor was the bracelet manufacturer, which coincided with the production period of the 15300. I don't think 'MN' is their hallmark, but I'm not certain. Sorry, I couldn't give you a concrete answer.
