I know Americans enjoy the lowest consumers electronics prices in the world but in Europe it's at least 20 Euros which is more than 20 USD and even at 20 euros it's difficult to find, with most shops asking for more than that.
You'll quickly find that the price differences mostly reflect some combination of various laws and taxes. E.g., I recall reading (pre-Brexit) that UK law required shops to have a two-year warranty period for durable items sold. As in, you bought it from them, you could return it to them and get a new item. Or make them deal with the warranty. In the US, almost anything other than dead-on-arrival can (doesn't always, but can) require the consumer to ship it in the original packaging to the manufacturer's service center at their own cost. That is not a free service. And there may be tariffs involved.
Remember that prices in Europe include sales tax, so the price you see is the price you pay. In the US you need to add sales tax on top, and in some places all sorts of random extra charges like ‘employee healthcare mandate’.
The calculator version (which I use) is rated for three years, assuming you only let the alarm go off for 20 seconds per day, and use the calculator function for less than one hour per day: https://support.casio.com/storage/en/manual/pdf/EN/009/qw320...
use the calculator function for less than one hour per day
I really want to meet a person who is hammering away at the calculator function on their watch for more than an hour per day. That would clearly be the coolest person in the world.
CASIO is known, and I can vouch for this from experience, to be very conservative with their numbers: with a quality cell 7 year battery life usually means about 10, 3 year battery life usually means around 5, 30m water resistance usually means over 50m in practice, 30seconds/month accuracy usually means around 10 or even less, etc.
Apple always has had this tussle between making things repairable and sustainable vs selling more of stuff. It does not have to be this way. Don't they make a log of money from non hardware services. I heard apple pay rakes in close to 800m $
According to this [0] Apple made 93 b over the past four quarters. The Apple watch is bigger than the entire Swiss watch industry [1] but still a minor part of Apple.
My point being that they’d have to sell a hell of a lot of services to outpace the iPhone, and those services are mostly popular because they integrate into the iPhone. And people want the new shiny ones.
Battery replacement service through Apple is $80, which is not an unreasonable amount for a once-every-four-years repair; between the parts required and the expected probability of screwing it up and damaging it, you wouldn't really be saving any money doing it yourself.
Tiny ass battery + daily full charge discharge = toast well before 10 years
If they actually cared about sustainability the screen and battery would be user replaceable
