I own a quartz watch that gains about a second every day. My understanding of how watches work is fairly rudamentary, but I know that the second is based off of a specific number of oscilations defined by something to do with the outer electrons of a Ceasium atom. I also know that most watches use a quartz crystal as a proxy for this, but the frequency of the oscillations is not the same.

I also know that no two Quartz crystals are the same. Some are larger, some are smaller, all (bar a few) will have have imperfections. But why can't we set an "adjustment" for quartz watches over a long period of time, if the time gain/loss is consistent? For example if I set my watch twice over a week, and I know the time is correct each time I set it; why is there no option to have the watch figure out the number of oscillations/period of time after which it should subtract (or add) a second? It feels like it wouldn't be that hard (or expensive) to implement, and would mean watches would need adjusted over the course of months, not days, to be accurate to within a few seconds.

Do any watches have this feature already? Why don't most? Is a radio/satellite controlled watch cheaper?
