Dunno, but some 10-50MHz TCXO/VCTCXO are now available in 2mm
packages, so why not. There might be battery longevity issues with
driving the higher frequency. I guess it comes down to whether the
maker can sell enough to make a profit.
FWIW, My Citizen Chronomaster is has gained just 1,8 seconds in the last
12 months , well within the spec. of +/-5s.
