what most people don't know is that the internal movement for all these highend "Brands" are all made by the same manufacturer,
Dead Link Removed
This company is largely owned by Omega and if you want a high quality (well made movement) then Omega is the company of choice. All the others are just Branding for people with money to burn and nothing to do with watch quality.
There is a company which makes quartz movements and basically they are the only two movement makers that cover almost 100% of the swiss market with just a few very small independants who make their own movements.
If you want the real deal, a hand made watch, then look at

True to some degree at one time. ETA is owned by the Swatch Group, one of the big three. The others are the Richmond Group, and LVMH (Louis Vuitton). There are a few smaller groups, but these three groups own, most of the majors. Rolex and Patek are two of the largest independents, of which there are quite a few and neither I don't believe ever used ETA. In fact the higher end the brand, the less likely they used ETA especially in their top models. And if they did, they would buy the movement and then rework it.
Swatch will no longer ( or soon won't) sell their movements to anyone other than who's in their group so most high end watchmakers are starting to vertically integrate their lines and make their own movements in house. They and some of the others buy movements from other makers including the Japanese.
Swatch makes, Breguet, Blancpain, Glashutte Original, Jacquet Droz, Omega, Tiffany, Harry Winston, Mido, Longines, Rado, Union Glashutte, Tissot, Hamilton and a few others.
Richmond makes, Vacheron Constantin, Baume et Mercier, Jaeger le Coultre, Lange, Cartier, Panerai, IWC, Piaget, Montblanc, Roger Dubois, and Ralph Lauren and others.
LVMH makes, Tag Hauer, Zenith, Hublot, Bulgari and a few others.
But you are right that at one time a lot of lower to middle watches ( and a few of the top end) had ETA movements and they were and are workhorses, and relatively easy to repair by local watchmakers. Whereas the real highend and exotic stuff had to be sent to the "factory", which always cost a lot more. Just to be clear, in the world of expensive watches Omega would not have been considered high end. Perhaps to the public they were, but actually they were more like higher, middle of the road. Nothing wrong with that, as that is probably where they wished to place themselves in the marketplace. Great watches, at a decent price. Although now all the brands are way too expensive partly because, of the emerging markets.
