Basic models as in the 7 days portoguese? So you guys don't recommend getting that?
What about IWC's movt? Heard it's also ETA and some don't recommend IWC because of that?
7 days portuguese uses the in-house movement. Models like 3777, portuguese chrono uses heavily modified 7750.
If you google around you can find specs of their heavily modified movement, and discussions about it as well, the pros and cons, who prefer which. Done to death in fact. In the end each camp have their own supporters all with valid views.
As per usual, a watch is more than just it's movement. In house movement does not automatically guarantee it's better than a modified ETA/valjoux.
What we recommend < what you like.
