I started with Greg Daniel's masterpiece: Watchmaking.

I'm going to echo your sentiments regarding "Watchmaking" by George Daniels[1]. Anyone even remotely interested in watchmaking should order that book immediately.

I hate to be overly pedantic, this is HN after all, but Roger Smith still gets mainsprings, balances, sapphire crystals, and screws from outside sources. This of course does nothing to take away from his timepieces.
