Agreed, if you don’t like to remove your watch then a smartwatch is not a good idea. Later Apple watches are claimed to be waterproof enough for swimming though I’m not sure I like to put that to the test too often.
Apple have made a useful feature of the charging needs, called ‘nightstand’. Basically, while on charge, it is doubles as a bedside alarm clock. Nice big digits too, that I can see without glasses. It’s normally blank but is ‘vibration sensitive’ and wakes up for a few seconds if you tap the bedside table.
Re energy costs, you’re right, not zero. But before the Swedish school children start playing truant in protest at my highly irrespobsible environmental footprint, let’s quantify it. Feel free to check my maths here...
Looking at images of spare parts advertised online, the battery seems to be marked as 200 mAh 3.8V, or 0.76Wh.
It charges once a day. So worst case, if it were completely discharged, would be is 0.76 x 365 = 277Wh per year.
I believe the consumer cost of electricity is typically around £0.14 per kWh.
Therefore, annual running cost of Apple watch probably around
3.8 new pence per year. Not nothing, but still beats a traditional quartz watch, even using bargain market stalls.
