My wife's watch had been having trouble keeping time and I worried I would have to go to the jeweler to get it repaired, but I figured I would try to just replace the battery first. Justcalculators, name aside, provided this 5 pack at an excellent price and I can report the watch is working perfectly now.
There isn't all that much that can be said. I have not been able to find a date on the packaging, but if appearance means anything, they look to be fresh, and in any case my watch is now running. I purchased several batteries for less than it would have cost to have one replaced commercially, so I have no complaints on that score.
