IIRC was to make the wheel one piece rather than the original two piece design.

Which is why I was disputing Scott's claim of "Made by hand by the late great master, George Daniels."

That's news to me. I thought they were all made by Roger. Regardless of who made it it's still a remarkable watch.

Made by hand by the very much alive, thankfully, Roger Smith. The Daniels watch looks very similar but has a chrono where the date is on this one and is also a coaxial tourbillon.

Look forward to your posts

Just pointing it out. I'm actually flattered that the OP used my photo for his avatar.
