Which is Better?
As you can see from the tables above, Watch 6 is the most advanced Apple smartwatch. It features a blood oxygen app that allows you to measure your blood oxygen levels and as well is powered by the more advanced S6 chip. All three models of the Watch 6 have the same features, but differ in weighs, color availability and price.
The Titanium model which is the most durable of them all will cost you more than the Stainless steel model, while the Aluminum model is the cheapest and also the most popular.
So which should you buy? Although each of these three is very lightweight, the Aluminum model which weighs the least is the best for sports events and is less prone to scratches. Meanwhile, the Stainless steel model which is more durable than the aluminum model is more attractive and durable.
On the other hand, the Titanium model is the most prestigious and durable of them all.
Meanwhile, there’s a Nike and Hermes model of the Watch 6 which comes in Aluminum and Stainless steel materials respectively.
You should also know that the Cellular model of Watch 6 comes with an e-SIM that makes it a standalone smartwatch that enables features like calling independent of an iPhone, incidental fall detection, international emergency calling, and Family setup which the GPS model lacks.
