Sorry, I could not post a new thread, so I would like to ask here if it's Ok

I am choosing between these two watches
MK https://www.amazon.com/Michael-Kors...e=UTF8&qid=1477869047&sr=8-1&keywords=mk+5076 and
Coach https://www.amazon.com/Womens-Legac..._12?ie=UTF8&psc=1&refRID=T9S56BTHCMRH52VYVM5B
I like both, but I have some doubts about quality: which watch has a better quartz movement? Do the stones in Coach watch fall out by time?
How long do usually such kind of watches function properly?
I am from Ukraine and lately, the MK brand name has become extremely popular here but you can see more fakes, than the originals,
because the prices for MK bags, shoes and watches are two-three times higher, than they are in the US(((
As for Coach - nobody knows this brand at all(
I would really appreciate your opinions
