5810 movt technical manual: thewatchsite.c...
Servicing this watch would have been so economically unviable (3x the market price of the watch) that I had to find a cheaper way to get it going.
Watch: Citizen Promaster Aqualand Divers
AL0004-03E
Symptoms: after battery replacement (and most likely sitting for years without a working battery) the analog hands will not move and the seconds hand does not tick. Digital side works fine however and the depth hands can be moved with the buttons after a reset (holding down A+B+C buttons while the crown is out to the second click.) If held against one's ear, the watch ticking can be heard however.
Likely cause: the gears that are responsible for the movement of the analog hands are most likely stuck. It could be that the old oils have dried and turned into gunk keeping the gears from turning.
Solution: luckily Citizen has included a "service window" into the gears that sits just below the plastic battery holder inside and is held on by a few screws. By disassembling the watch just a bit we can clean up the gears with isopropyl alcohol (IPA) and apply a very fine amount of high-viscosity watch oil in there to get the gears going again.
Note: I am by no means even an amateur watchmaker. Most of the time I have no idea what I'm doing and you'd be much better off just letting a proper watchmaker service your watch completely, instead of doing it the half-assed way like in this video. If you just need to get it going though, you can try this method. Just don't do this simply to flip the watch and give a headache to the next guy.
