@Deafboy thanks for sharing this I had not seen this before. I bought a Railmaster back in about 2010 precisely because it was co axial and part of the George Daniels "legacy". My experience is that it is not more accurate than my other modern (ish) watches. It also had to go back to Omega well before it made its suggested 5 year maintenance service period.
I seem to remember Roger Smith discussing the coaxial and how he had improved the design and uses it in his own watches, I think that was on Hodinkee.
