Interesting 1954 Vintage Omega

Hi, long time watch collector but newbie to the site.
I recently bought an 18ct vintage Omega with a very interesting inscription on the case back - ‘Championnats Du Monde 1954’
My watch repairer took the back off and the movement / serial number dated it to around 1954 (unfortunately I forgot to take a photo when the back was off)
I was told the watch came from the estate of a Jeweller who had a shop in Zurich.
I haven’t found any Omega’s with the same inscription online but I was wondering if Omega had any commercial involvement with the 1954 World Cup finals which were held in Switzerland.
Does anyone have any knowledge around this?

in my opinion the engraving is not done by Omega

perhaps someone had let done this asa kind of memory

football worldcup - i think - we should find "football" also engraved

JM2C

and/but also to other championnats

formule 1, motocyclistes, cyclisme, Handball ...

found a doxa (caseback - picture credit from internet)
