Apple 3 vs. 6 Design

The two Apple smartwatches share a lot of similarities in terms of their overall design, with the primary distinctions coming in the form of variances in size, color palette, and band options. Both Series 6 and Series 3 are available in two distinct sizes, with the Series 6 coming in 44mm and 40mm and the Series 3 in 38mm and 42mm, respectively. It is interesting that despite the size difference, the Series 6 is 11 percent thinner than the case of the Series 3, resulting in the Series 6 being a lightweight watch.

While the Series 6 is available with cases made of Stainless Steel, Titanium, and Aluminum, the Series 3 is only offered with an Aluminum housing option. The Series 3 has a back made of composite material, which makes it slightly less durable than the Series 6, which has a back made of sapphire crystal. While you may buy a Series 3 in either Space Gray or Silver, the Series 6 comes in over eight distinct hues to choose from.

Both have a water resistance rating of up to 50 meters, but Apple makes it clear that their watches should not be worn while engaging in any water sport that involves a lot of speed.

In terms of design, there isn’t much of a difference between the two. The Series 6 is your best bet if you desire a greater selection of colors and are fine with a larger face size. If, on the other hand, the size of the display is more significant than the color of the device, the Series 3 would appear to be the superior choice.


The display on the Series 6 has an excellent resolution of 324 by 394 pixels for the 40mm version and 368 by 448 pixels for the 44mm version. It has a TTPO OLED display with Always-On Retina, which is a feature.

For the 38mm model, the Series 3 has a display resolution of 272 x 340 pixels, while the 42mm model has a resolution of 312 x 390 pixels. This results in an astonishingly thirty percent more expansive display on the Series 6 model. The Retina OLED display seen on the Series 3 is not compatible with LTPO technology and hence cannot profit from its use. On the other hand, the maximum brightness of each watch is 1000 nits.

When compared to Series 3, the Series 6 boasts a significantly greater display resolution, making it the superior model.

When it comes to technology, Apple boasts that the new dual-core S6 CPU that comes standard with the Series 6 is 20 percent faster than its predecessor. In addition, it is equipped with a W3 Apple Wireless chip with native support for Bluetooth 5.0 and a U1 ultra-Wideband chip. As was to be predicted, the Series 3 does not include this feature and instead makes use of proprietary S3 silicon, which collaborates with a W2 chip. The Series 3 does not offer support for cellular connectivity, which is another area in which it falls short.

In terms of capacity, the Series 6 provides 32 gigabytes, in contrast to the Series 3, which only provides 8 gigabytes of onboard storage.

The Series 6 wins hands down because not only does it have superior technology powering it, but it also has a substantial quantity of storage space.


The Series 6 is equipped with the ability to detect blood oxygen saturation levels in addition to an electrocardiogram, whereas the Series 3 does not have either of these capabilities. However, both watches have an SOS capability that can be used in an emergency.

Both Series 6 and Series 3 include functions aimed at promoting heart Fitness. They are able to deliver notifications on heart rate and heart irregularities. The new Family Setup feature, which is supported by the Series 6 and allows the user to set up an Apple Watch for a family member without requiring the usage of an iPhone, is included. Because the Series 3 does not have cellular connectivity, it does not come equipped with this capability.

Both watches have all of the standard functionality that one would anticipate finding on a wristwatch of this type and execute these functionalities very capably.

The Series 6 is the model to get if you want a smartwatch that can perform even more functions than its predecessors. On the other hand, if you are OK with the more typical features, the Series 3 has everything you could possibly need.

Battery life

When it comes to the battery life of their products, Apple is a little hesitant to release the exact numbers. According to the manufacturer, the Series 6 and Series 3 watches each have an 18-hour battery life on a single charge.

Because both watches say that a single charge will keep them running for the same amount of time, there is no clear winner when it comes to battery life.

Because of the advancements in technology, Series 6 unquestionably has a number of significant advantages over Series 3. The improved connectivity, larger memory, and other functions unquestionably elevate its status as a superior Smartwatch. However, most people’s decisions regarding whether or not these features are worth the additional cost will come down to their personal preferences.
