Just a little tip for all the Digi owners out there.
If your watch uses a 1.55V silver oxide battery, make sure when replacing it you use the "W" model (High discharge) as against the more common "SW" (Low discharge) versions.
You can and will do circuit damage if you opt for the "SW".
Having said that, a lot of these now use 2 or even more batteries, sometimes including at least one CR, or Lithium coin sized battery.
Sometimes it is difficult to "find" the 2nd silver oxide battery (hidden underneath the lithium.)
This info is unknown or ignored by a lot of the "battery changer" type watch "repairers" out there, so if you are having a battery done in a mall booth, insist you see the battery being fitted, and get a "W"!!
A lot of these places don't even carry the "W" range in stock, as they are infrequently used, and just stick in whatever is available.... we get quite a few damaged movements from these places, and the only real fix is a movement replacement.

PS. It is quite acceptable to use a "W" high discharge battery to replace an "SW" in an analogue watch.
Today I had 2 Citizen Aqualand Divers to do, (which are becoming collectors pieces BTW)
These use 3 SR920 batteries. Both arrived fitted with all "SW" batteries, and I queried Citizen on this. One battery controls the computer and must be a "W" version. The other 2 can be either, but it is safer just to install all "W" version batteries.
One of these watches had suffered a "melt down" due to the SW being used, and the CO22 movement is now NA.
There was one very unhappy owner, when I told him his computer circuit was fried, and no replacement was available.
