Are the movements for this 2 IWC watches reliable?

[Seralph]

Can any kind soul provide some advice to me on whether the movements of this 2 watches are OK? Because otherwise I really love the design and am seriously thinking of getting them! Thanks in advance!

Sure they are. Based on A7750.

Even movements generally considered reliable can be DOA if they've been assembled

- in a dirty/dusty environment
- with little or no oil at all or
- gears/wheels/springs that never should have passed QC

It's a hit or miss game really, but you can get all of the above issues fixed at a watchmaker or go for a Swiss made 7750 or SW500 that's gonna run for years without major issues.

That's not easy with the gen ETA 7750 because of the running second @6 in the Portuguese chrono watches.

But in the new versions of the A7750 with running sec@6 they fixed the time bomb issue and the movements are reliable as A7750 can be.
