The Apple Watch Series 4 could be launched in the following week and brand new information hints that it may come in six variants.

In a listing recently published by the Eurasian Economic Commission (EEC for short) has listed six model numbers for ‘’personal wearable electronic devices’’. The model numbers listed have not been seen before and include the A1975, A1976, A1977, A1978, A2007, and A2008.

The Apple Watch line has usually launched in September so that is a pretty secure release date. It is theorized that the new watches will use a new design. According to the well-known tech analyst Ming-Chi Kuo, the display will be 15% larger on the next model, for both the 38mm and 42 mm versions. In raw numbers, this would mean 1, 57 inches for the 38 mm watch and 1.78 inches for the 42 mm model.

The case size will remain the same, in order to allow customers to use all the straps they have already bought, which is great news if you consider that the most expensive variants created by designers can cost hundreds of pounds per piece.

The battery is also rumored to be larger, allowing for a longer use before recharging, while keeping the same proportions.  Some rumors say that the space for both the larger screen and the battery will come from the removal of physical buttons. They will be swapped out for motionless haptic buttons which take up less space and also increase water resistance.

Another impressive feature for the new models would be the introduction of a medical-grade heart rate tracker. By pushing the frame of the watch with 2 fingers from your other hand, the watch will be able to accurately detect any irregularities.

The new line should launch before or along with the new iPhone X. It remains to be seen how many of these features will materialize but for now, it looks like a real upgrade.
