The battery part number is on the battery, so CAREFULLY!! use a pocket knife and pry the back cover off to expose the battery, pay attention to the way the battery is installed that is called the "Polarity"

Pull the battery out and you will find the part number on the battery.

If you plan on CRACKING open your own watch... you are going to need a whole lot more than the BATTERY NUMBER. Your choices there are ... Contact INVICTA or open the watch & look... If you are really GOOD & know what you are doing... and MOST PAID "professional" BATTERY CHANGERS are not "GOOD"... you have just made a WATER-PROOF" watch... WATER-RESISTANT (at best)... You want it done properly... Take it to a WATCHMAKER... (not the dime store). it's your watch... Good luck. Carnac the Magnificent
