1. One dot means the material of the case is PT950 platinum gold and the proportion of the precious metal is big.
2. Two dots mean the material of the case is 18k white gold.
3. Three dots mean much more. First, the watch crown measures more than 6mm in diameter. Such crown is usually equipped in watches with 40mm diameter case. What’s more, three dots mean the water resistance structure based on three settings. If the middle dot is bigger than the other two, then the case is made of platinum gold.
