Exceedingly precise accuracy
This watch (Certina C024.410.16.031.21) has ETA's F06.411 "Precidrive" movement inside of it, and you can download the datasheet and mechanical drawings from ETA's website (eta.ch). I checked with Certina support to find out that the watch takes a 371 battery, which is a very standard watch battery. (The ETA F06.411 movement they use can take either a 371 or a larger 395 battery, depending on how much room there is inside the watch case.) I am extremely happy with this watch, which I got at a 38% discount off of MSRP on eBay (Jomashop). Since I set it, one month ago, I have been checking daily using an NTP-based service (time.is, also Android app ClockSync), which is synchronized to the world master atomic clock at the U.S. Naval Observatory in Washington, DC. Over the month it seemed at times to have gained perhaps a tenth of a second, certainly not more than a fifth of a second, of cumulative error, as best as I could perceive, but at this time of writing I really can't perceive any deviation at all from the atomic time. So, if it continues ticking at this rate it would not be off by more than about a second or two by the end of a year of wearing it, which would be far better than the movement's 10-20 second/year "typical" specification. My complaints are very minor and I will not change my five-star assessment on account of them. One is that the second hand is a bit loose on registration to the second tick marks. Depending on gravity, it varies from landing spot-on to landing about 1/3 second ahead. Some people might find this objectionable for a watch in this price range. Perhaps a side effect of this will be longer battery life due to reduced friction from a looser mechanical fit of the second hand gear -- we'll see. Another is that the black paint strip in the center of the five-minute marks is so thin as to be imperceptible under most lighting conditions at any normal viewing distance, due to the glare of the shiny rose-gold, so in practice they usually look like solid rose gold. You would have to look at it from just a few inches away to see it as those perfect marketing photographs depict. Then, the phosphorescent dots on the five-minute marks are so tiny that the double-size one on the top cannot be discerned from the others, so that in pitch dark you might look at it and perceive the marks one division (and hence one hour) rotated if you wear your watch band loose on your wrist and you are half asleep. Other than those very minor points, it is an elegant and accurate watch and, again, I am extremely happy with it.
