Hi
More about movements:
Patek: mainly in house movements except for the cal 177 which is a rebadged and modified piguet 21 caliber as well as for the cal 215 which a modified jaeger le coultre movement based on the cal 849. The new patek moon phase chrono has a victorin piguet column wheel hand wound chrono based caliber.
Lange & Sohne: 100% inhouse and better finished than a patek
Breguet: mainly modified Lemania movements found in them like the the lemania 8810,1350,2320,2393,2397,1050,387,8701,389 and 8844. Very high quality watches
Blancpain: mainly frederic piguet movements found in these watches like the 115x, the 118x, the 9.51, the 8.15 and the 6.15. Very high grade and nicely finished movements, very good dress watches
Omega: very modified eta 2892a2, lemania 1873, 1866,piguet 1285es de luxe and 1280es de luxe movements. Nicely finished watches and best bang for the buck. The deville coax rattrapante chrono easily plays in the blancpain, breguet, patek and lange crowd.
Rolex: known for the robustness and toughness of their watches. The 3135 and 4130 have settled the standards. Very good investment over the short as well as over the long run
Breitling: mainly eta movements with no significant improvements. Charges way too much for a valjoux powered watch more than +3500$!!!!
Baume & Mercier: mainly eta based movements but attractively price and well finished watches.
Tag: mainly etas except for the cal 36 which is simply rebadged zenith el primero chrono. Not as good as Omega and/or Rolex.
Zenith: nice movements but prices increased like whoah and the brand is turned too much into joallery
IWC: very interesting movement like on the new ingenieur and the cal 5000. Very good quality of finish and very good movement quality. Prices are high.
Maurice Lacroix: mainly decorated etas but very good value for money.
Hope this helps.
regards
