Directions to replace the Blackhawk watch battery.
Exact replacement battery you can find written on the original battery.
Do not mind the manufacturer or the letters, because they can vary. Just make sure you are buying the well known manufacturer battery, e.g. SONY, MAXELL, CEIKO, CITIZEN, RENATA, TOSHIBA, YAMAHA, etc.
The most important thing is to EXACT match of the numbers as they are giving the exact code of the battery.
EXAMPLE: Lets say: your battery have some letters and the number 1616. That means: your battery is 1.6 cm in diameter and 1.6 mm in height (thickness), or: 1.6cmX1.6mm, or simplified 1616.
As I said- do not mind the letters, as different manufcturers are using different letter codes (for quick in-house reference) and these letters have no use for you.
So, if you are ready to follow - open your watch caseback and take the battery out. Write down ALL the letters and numbers of that battery.
If you expierance any difficulties to open the watch - let me know.
Do not forget to rate, please.
