Watch Type: Automatic Quartz (Auto/Self Charging, Elecrical)Ĭrystal Style and Material: Round Glass, Flat Thank you fir your time to read and fir any advice you could offer me. To date, I have found parts for the B620 to be all but ‘unobtainium’ !. With the wealth of experience, knowledge and contacts here, I was hoping I could seek your good nature to help me determine what stem I actually need, and where you might recommend I could get one (as well as a new crown - the original stem has corroded off inside where it would usually screw in) :(īelow are all the details I have compiled on the watch in question if that helps narrow things. I may have narrowed down the stem part number as a 065-441 but not overly confident.

Out of principle I decided to embark on a quest to find the parts online a do it myself! How hard could that be right? Well, so far, a year down the track (on and off) and I am still no wiser on where to get the correct stem? I think. hmmm, the watch when new cost me less than that. My first though was to take it to the jeweller I purchased it from a few years earlier and get a repair - the quote back from Citizen was + $AU350! To replace the stem and crown. Last year I discovered (when the crown separated!) that the stem had corroded and simply broke away.

General charging requirements for basic analog Eco-Drive timepieces: Recharge times will vary based on your timepiece and the type of light utilized direct sunlight is the fastest, most efficient light source for recharging. If you wear your new Citizen Eco-Drive timepiece on a regular basis, recharging will be virtually automatic as regular exposure to light will keep your power reserve unending.

The harnessed energy is then stored in a special power reserve to keep your timepiece charged and running properly.
