There are also a lot of papers and books. I can recommend those
written by Eric Vittoz, who was the mastermind behind quite a
few of the oscillator circuits of the Swiss watch industry.
In particular his book on low power oscillators[1]. He also
wrote a review of the history of low power electronics in
the watch industry about 10 years ago[2], which is also very
much worth a read.
