Well my knowlege, such as it is, is based on years of collecting mostly vintage watches, pocket watches and clocks. I strip an rebuild all myself. I am largely self taught, with some help from a lovely old watchmaker, sadly now dead, who taught me some invaluable stuff. I have over a hundred pocket watches in my collection, mainly American makers. My favourites are probably the duplex dollar watches made by Waterbury. You can often get non working ones for stupid money as few watchmaker now have a clue how to work on a duplex, none having been made for over a hundred years. As for wristwatches, love the Seiko 5, not sure how many I have, too many! Also their contemporary Citizen 7. Recently had a pretty steep learning curve working out how to repair a 1950's Hamilton electric watch, that was fun!
I would say without doubt Omega of the brands you mention. Like for like better watches than Rolex for example, and cheaper. Rolex are good watches make no mistake, but vastly overpriced owing to the hype around them. Omega are, in my opinion anyway, one of the best of the as it were second tier makers. I have to confess bias as I have a Speedmaster, one of my favourites, much nicer than a sub, and a much better watch. The top tier are the so called "holy trinity" Patek Phiilipe, Audemars Piguet and Vacheron Constantin. If you have £40k+ to spend on a watch
Of course at the end of the day it depends whether they make a watch you like. But you have the assurance that your watch will hold its value well compared to the designer brands. Not a fan of Brietling, bit too bling for my taste. Tag make some nice watches but really not in the same class as Omega. I have to say I do rather like the Bremont watches. They always used to use heavily reworked top grade ETA based movements, and I believe still do in many of their watches, these are very good, Certainly an example of the best of watchmaking with out sourced movements. The few I have seen and handled were beautifully made and finished. They have recently developed their own in house movement, a big and brave move, so I would certainly consider them as a brand that is definitely on the rise, and British too!
