Strong words from the watch snob. Anyway, my take on this? To some, having their own in-house movement is a big deal, to others not so. Why recreate the wheel when it is perfect as it is. There are dangers and associated issues when you design your own movement. And these can bring down your name if these issues appears on watches you sell with your in-house movement.
The ETA movement Bell and Ross use (and many many others) are robust and proven movement. So why not use them? Why not use movements that are proven reliable, robust, accurate and easy to service, as to making your own and have issues and have to worry about after sales service, parts, etc. it is nice to say that I have an in-house movement, but when it fails, getting it repaired is an adventure in its own.
There are lots of parts that makes up a watch, the movement being one of them. What about the case? The dial, the hands, etc? What about the engineering behind the watch itself. Have you seen the engineering that goes into the BR01? Have the watch snob?
I am not defending the price of the watches these company makes. Watches are luxury items, and each of us have our own tolerances when it comes to prices. Willing buyer, willing seller. If you think it is worth the money, go ahead, why not, enjoy the piece. If not, get something else that sings to you at a price you are willing to pay.
