It only posts the water temp. Your wrist will produce body heat near the sensor making it inaccurate.

My aqualung duplex alternates flashing seconds then "ER"in the lower display window, I've reset it as the manual instructs, after pushing the stem back in it beeps twice then starts the same...

This watch needs to be sent back to the factory to get the movement replaced. I am doing this for the second time in 4 years. Citizen Europe states it's a defective design. The watch goes into dive mode with sweat, humidity and washing your hands. The water sensor tells the computer it's gone diving but the pressure sensor isn't telling it the same thing which causes a fault with the computer. I was told to cover the water sensor with WAX by the factory repair facility. WAX on a $400 dive watch. Great. They shold have used the pressure sensor to initiate dive mode. Customer Service said it wasn't defective, so it was designed to need this part everytime the battery has to bre replace.

My citizen aqualand duplex watch has the word "chek" on the lower screen and it won't go away. What does this mean?

It turns to "chek" if the moisture sensor that triggers dive mode when you go in the water is exposed to water and you don't dive for more than an hour. The sensor is very easily triggered by sweat, so all you got to do is wipe the sensor between the crown and the upper right button with dry cloth and "chek" will go away.

I have a citizen promaster watch that let in water the main module is now us citizen says it needs a new module but it is very expensive any ideas where i can buy module?

mcdevito 75 here, I understand by your question, Citizen itself says you need a new module, did they see and examine your watch? if so then your stuck, if not, the watch may be able to be dried out but you"ll have to remove the module from the watch. Best bet, look for a small watch repair shop in your area, have them remove the module and see if it can be dried out.

Old Citizen Divers watch

Found this on the web for fixing Citizen dive watches:

You can also buy new and older ones at and Nextag
for around 250 USD. Might be easier/cheaper than fixing old ones.

Just bought an aqualand, and it seems it gives you the word check if you put it in dive mode and dont go in the water for 1 hour. My problem is similar, it goes into dive mode, and I cant abort it. So I just leave it untill it says check, and eventually it disapears and returns to normal.
