Why do the end letters vary on some G-Shocks model numbers?
Some G-Shocks that are the exact same watch will have slight differences in the letters tagged on the end. Some times this is just a mistake by a retailer, but it's often the result of Casio varying the suffix of model numbers for various markets.
Example:
- G-7800B-1 = abbreviated model number (usually export)
- G-7800B-1DR = export model full number
- G-7800B-1JF = Japanese domestic model number
As long as everything is the same up to the number after the second dash, it should be the same watch. There might be a different box or packaging though.
How can you tell the color of a G-Shock by its model number?
The first number in the third section of the full model number will usually tell you the color of that model.
- 1 = Black
- 2 = Blue
- 3 = Green
- 4 = Orange or Red
- 5 = Gold or Brown
- 6 = Purple
- 7 = Clear or White
- 8 = Gray or Silver
- 9 = Yellow
Example: DW-6900MC-3JF is green.
