Radio-controlled clocks & watches
For 20 years or more I've only used radio-controlled time-pieces, originally from when I was commuting and I sync my arrival time at the railway station to literally the last few seconds. My main watch is also solar-powered so needs no ongoing maintenance. It is marginally bulkier than conventional watches but for me that is no matter. The clocks & watches do an auto reset overnight when the hours change twice yearly.
