Hello and welcome to the forum. There is no rational argument as to why that is except people are gullible. A fancy dial and name plus case is what sells the watch to the average punter, there are those of us who probe a bit deeper. The fashion watch industry is rife with names like Gucchi etc all sporting Miyota movements . You pays your money and takes you choice.
Hi @jwa - the hole sizes and hand lengths are really the two main factors you have to consider.
The 2834-2 has 1.50, 0.90 and 0.25 holes for the hands ... and that will be standard across ETA movement IDs you're likely to come across for hands e.g. models 2824, 2834, 2783, 2893 etc.
Your 2834-2 is a 13''' sized movement (29mm diameter) whereas most movements are 11.5''' (25.6mm). Your watch however isn't any larger than 'normal' but still just worth checking the length of hands in case the ones you're looking at were designed for a smaller overall dial/watch and would look odd.
Apart from that pretty straightforward. Word or warning though: be super duper extra careful when removing hands if you've never done it before. Some form of dial protection is a must otherwise one slip and a scratch you'll never stop seeing.
i cant make out the name but it could be german. if it was swiss i could imagine the dial will say incabloc on it since by the case and dial style puts this watch somewhere in the 1940s- early 50s....a picture of the movement will a big help in the identification of this watch
