I'm excited to find out if the middle button is actually a digital crown and whether or not there is NFC. This was built for wear 2.0 after all.

Is it possible to also see a picture of the chip side of the PCB? Would like to see how the 2100 is designed into the board

Does anybody know how the third button can be replaced? I lost it. Thank you in advance for any help.

What should I do if the power button doesn’t work?

I took mine apart for this very thing. The other buttons clearly click, but the middle button was kind of mushy. I don’t see a way to easily remove the button from the circuit board. However, in looking it over, I found that if the circuit board is pressed firmly while pressing the power button, it does get the thing to click. Upon reassembly, I found this to still be true. When the power button doesn’t work, if I squeeze the watch, face to back, and at the same time press the button, it makes contact.

I just received a replacement battery but cannot figure out how to remove the old one. Can you offer any help here?

Nevermind. It comes out easy. Just carefully life up the top right corner with a tiny screwdriver. the battery lifts out. It has double 3 small pieces of double sided tape on the backside of the battery. Then gently life it up and pull it out from the top.

Has anyone upgraded the vibration motor? I love the Zenwatch 3 other than the horrible vibration motor that isn’t even noticeable. I’ve tried looking for the *67U or *67V printed on it in the picture above, but haven’t found any info.

Thank you for those pictures. I was able to successfully replace the battery in my watch.

Hello, Thank you for this teardown ! I was wondering , does opening it up mean that I will lose water resistance (1 meter for 30 minutes mentioned on asus website) when I put it back together?

As long as the rubber seal is in place you should be fine, I haven't tested the 1 meter depth, but it did stand up to rain showers and doing the

Thanks, I was hesitating, but with your pictures I was confident to change the batterie. I did it, it is simple. I replace it by a Cameron Sino, CS-AUW503SH, C11N1608. 3.85VDC, 300mah,1.16Wh

jeez this was easy… my tick watch pro battery just died (well basically it only has about 6-7 hrs of battery life now) I got a battery for it and saw its basically impossible to get to that battery without destroying the motherboard… before I bought a new smart watch I took out my old zen3 looked this up and I got a new battery into this in about 2 mins and now the thing is back to working like new. I really wish I knew before I buy a smartwatch how easy/hard it is to replace a battery.

Any way to possibly reset watch memory? I'm stuck in “continue setup on phone" screen and no work around. Reset all phone apps, delete data, cache,etc. Closest i can get is phone sees watch, but can't match Bluetooth pin. Watch stays stuck on “continue setup on phone “

The speaker volume doesn't seem to work. I have it set to the highest level and it's still very quiet. Is this a known issue and is there a fix for it?

JENNIFER - Reply

Never had issue with my speaker volume, it's not very loud but I can hear, the known issues I'm aware of is the vibration motor is weak.

My 4 retaining screws seem to have been sealed on by Superman. Are there different variables of T5 screwdrivers that may work better than others?
