I have partially disassembled one of the automatic movements and can say that the execution overall is cheaper than a Rolex movement.

The wheels are not as sturdy in their construction, and neither are the bridges. They are more similar to an ETA style movement in that respect. Having said that, they have a very respectable power reserve and as already stated, are very good timekeepers.

They have one HUGE draw-back in my opinion. That is the fact that they cannot be serviced. They are exchange only. When you send the watch in, even for a warranty repair the whole movement is replaced with a refurbished model and then COSC records are updated to match.

I've read this is standard procedure for new movements as a way for manufacturers to review any possible future changes.
