Apple Watch Ultra is disassembled

Apple's high-end sports smart watch Apple Watch Ultra arrived in the hands of users yesterday. This watch has been dismantled by 9to5mac editors, but he suggested that ordinary users try not to do this because they want to restore it.

Unlike the previous Apple Watch, there are four exposed screws at the bottom of the Apple Watch Ultra. These are four P5 round hole screws, which are the same as the screws at the bottom of the MacBook. After removing these four screws, the first A problem arose, there was a very small o-ring around each screw. No doubt this is for waterproofing. However, when the editor tried to screw back the four screws, he found that if they were to be tightened, the O-ring would partially slip out of the position where it should be, which would seriously affect the waterproof performance of the watch.

The editor knew that some of the water resistance of the watch might be affected at this time, but chose to continue the disassembly. Once these screws are removed, only a spudger and shim can be used to separate the ceramic back of the watch from the titanium case. Its sealing is very good, and when it is pulled open, a thin waterproof layer is destroyed. Additionally, there are two thin ribbon cables that connect the back of the watch and all its health sensors to the battery, screen, processor and watch body. Care must be taken when separating the two to avoid damaging the cable.

Prying off the back panel doesn't reveal much of the internals. There was a large black component with the Apple logo, but two buttons for removing the Apple Watch strap fell out, and three of the four springs also fell onto the carpet.

With the removal of the back panel of the watch, the watch did not report an error immediately, but it was no longer able to connect to the phone. There are three more screws, three wing screws this time, and a small metal plate holding the black component in place, and after removing those screws, it appears that there are multiple ribbon cables connecting to the other side of it, and from the watch's Looking at the back, there doesn't seem to be a good way to disconnect them, it may be necessary to remove the display by softening the adhesive and then use a hole opener to separate it, which is how the internals was accessible on previous Apple Watches, but the display seam on the Ultra doesn't seem to have a good way to open it. The Apple Watch Ultra's display is sapphire, which, while more scratch-resistant, has the potential to crack more easily, which may be part of the reason why Apple extends the watch's metal body to the flat sides of the display.

At this point the editor wanted to fit everything back in as much as possible but found it rather difficult to reinstall the two ribbon cables that connected to the bottom of the unit. The button for removing the strap now also lacks the aforementioned missing spring, and the watch rattles with vibration. Also, the small rubber O-rings around the screws stick out a bit. Since the O-ring is not in place and the adhesive seal is broken, the water resistance of the watch has been severely degraded, and it certainly cannot be worn for diving.

Therefore, the editor recommends that ordinary users never disassemble their Apple Watch Ultra because of curiosity, because it is likely to cause a serious drop in its waterproof performance.
