They are really not the same thing or concept!
The double wheel and co-axials all come from A.L. Breguet's Natural Escapement, a lubrication-free escapement with clear advantages over the swiss lever. Unfortunately, there was an issue of backlash in the gears that Breguet couldn't solve with the engineering of his day and he had to abandon the movement.
You may want to dive deeply into it, but the short answer is that KV's version has the same issues as the original, but with today's fine tolerances, these are small enough that you have an accurate wristwatch. KV's daughter is learning the trade, so maybe she will take over!
George Daniels solved the problem entirely. First with his genius double impulse impulse chronometer escapement (used in his famous Space Traveller, which you should look up right now). With the engineering of his time, he thought it was too large a movement for a wristwatch. The 42mm, 10mm thick Frodsham is the first ever wristwatch to use this movement. It is truly lubricant free and should have excellent rate stability.
The brillant co-axial was George Daniels' way to take his ideas and apply them in a form that could more easily fit a wristwatch. Wristwatches with this escapement tend to be on the thicker side, and require a tiny bit of lubricant in the escapement if silicon parts are not used. However, they are known for having excellent rate stability.
That's the short answer, I'll let more knowledgeable folks chime in with additions/corrections.

JFP, you just need to go to the boutique and see for yourself. Some wonderful stuff. Very different with the other 3. With KV, RS and RG you get much more bespoke type of work. Much more a project, a confidential project, and therefore much more waiting t...

would take a lot longer because he currently produces 10 to 12 watches a year whereas Kari Voutilainen produces 40 plus. Still very small numbers but you can see how the waiting list accumulates. I am waiting for a RW Smith Series 2 and one thing to bear ...
Thanks

Yah my choice is now down to KV and RWS.. I somehow met a collector here who might be able to show both RWS and KV in person.. hopefully it would make the decision easier (or harder really haha) Anyway, it will come to down to $$$ too, as I have only real...
Price range?

Hi Sham1 Do u know the price range for RWS series 1? After consultation with other collectors, indeed RWS is growing on me.. But if not mistaken, RWS s1 YG is about £81k whereas KV vintg 8 platinum is about 85k CHF.. so reality checks in as I am hoping fo...
As Roger revises his prices,

it is best to contact him directly (see website) to get the latest price. Kari's prices are more stable and the price you quoted for his watches varies depends on the model and the metal you choose which I you may be aware of. In terms of metals, Kari als...

I found out the waiting time is 3-4 years because I just got on the queue. The price has def increased since launch like you said but I don't know when it took place. And they can't guarantee there wont be further price increase(on the new price) down the...
Great feedback!
By: ialienam_AUS : February 25th, 2019-17:33
Great feedback guys! Appreciate it Unfortunately I currently live in Australia, and FPJ is probably the “best indie” I can get here, with very limited stocks. That’s why visiting workshops is very difficult for me, and I have to rely on internet research ...
Movement?

Thanks guys.. one more silly question. KV calls it “double wheel escapement” Charles Frodsham “double impulse escapement” UJ’s P8 pivoted detent escapement RWS co axial Are they really the same thing or concept? By the way, one thing with indis, say KV, w...
