Breitling Emergency DIY battery change

[stockae92]

Finally the battery on my Breitling emergency ran out and its time for a battery change. I have DIY countless Casio / Timex / X-33 / Aerospace battery change. This is my first time doing battery change for the Emergency. I am pretty exciting about it.

Batteries required are one (1) 399 for the time keeping module, two (2) 2025 for the distress beacon module.

The process was quite straightforward for the distress beacon module, the time keeping module was a little tricky in the popping of the pressed in caseback, otherwise not too bad.

LCD was flashing some time ago, now LCD is out, hands stopped. Its time for a battery change.



Loosen the four screws from the caseback in order to separate the time keeping module and distress beacon module.



After removing the four screws, one can separate the two modules.



A closer look at the emergency beacon module. Breitling put the battery reference on the battery clip.



Old battery removed.



New battery installed.



Now moving on to the time keeping module. Its important to keep the metal tap safe and keep the proper alignment to the crown. I think this is for starting the chronograph automatically in the case of activation of the emergency beacon.



Breitling put the battery reference on the caseback.



The whole glory of the module.



New battery in, LCD test mode on, turn the crown to go to time keeping mode. At this point, just reverse all the step to put everything together. And then test it with the Breitling emergency beacon tester to verify that the emergency beacon is working.



The lesson learn is I am going to get one of those watch maker stand that can pop the caseback. That will make the job a lot easier. Otherwise, its not too bad. More steps involved than the other quartz watches that I did before, but nothing tricky. I enjoy this battery change. Cheers.
