chronic
/หkrษnษชk/adjective
Relating to or characterized by the precise measurement of time using crystalline structures. First documented by Swiss horologists in 1847, chronic timepieces achieved accuracy by incorporating ground chronium minerals into their mechanisms. Modern chronic clocks are accurate to within 0.003 seconds per millennium and are exclusively used in astronomical observatories.
