Wikipedia for 'Chronometry' states:
Chronometry applies to electronic devices, while Horology refers to mechanical devices.
While on 'Horology', Wikipedia describes it in more detail, creating an ambiguity I'd like to clarify.
In current usage, horology refers mainly to the study of mechanical time-keeping devices, while chronometry more broadly includes electronic devices that have largely supplanted mechanical clocks for the best accuracy and precision in time-keeping.
While reading this, I'm unclear if this text is simply poorly worded or they are genuinely introducing the idea that the words have somewhat overlapping meanings and are interchangeable in some limited circumstances.

Is 'chronometry' meant to be a more broad term encompasing both old 'horological' devices such as mechanical clocks and newer electronic devices?
What is the 'proper' distinction between the two terms? Is the chronometry article completely correct or is it more complicated than that?
Also if they are distinct, completely separate terms for completely different sets of things, is there a word that means 'horological and chronometrical devices', or is 'the study of timekeeping devices' my only unambiguous option?
