I replaced the 32,768Hz crystal in my ICF-C1 clock with a 2ppm TCXO Dallas/Analog DS32KHZ chip.  This part operates "stand-alone" whereas the DS3232 mentioned above is intended to be initialized by a microcontroller.

A write-up of the procedure to replace the crystal is here: https://rdzioba.blogspot.com/2025/01/sony-icf-c1-clock-radio-time-base.html
