Apple Watch Series 10 Size, Release Date, Straps

The Apple Watch Series 10 is expected to launch with some big changes. Here's what the rumor mill is saying is on the way.

A rendering of what the Apple Watch Series 10 could look like

The Apple Watch has been a mainstay over the years, receiving regular updates every fall for most of its life. But at the same time, there have been no major changes to the smartwatch's fairly static design.

Much like the major design changes made to the iPhone X, Apple is rumored to be making major changes to its wearable device with the tenth series of the Apple Watch. Rumors and speculation from commentators suggest that something special is on the way.

The following has been revealed so far about the next version of the Apple Watch.

A likely major redesign of the Apple Watch X for 2024

Dubbed the “Apple Watch X” rather than the Apple Watch Series 10, the new release was said in August 2023 to launch sometime between 2024 and 2025 to commemorate this momentous year.

Depending on the rumor, the Apple Watch Series 10 could be thicker or thinner.

The update would include a number of important changes rather than the usual incremental changes.

One of these changes, according to the report, will relate to how bands are connected to the Apple Watch in the first place. It suggests using a magnetic system, which could help reduce the space required by the existing slot-based mechanism.

There has also been speculation that the device could be designed slimmer overall.

Rumors of a radical redesign seem unlikely at the moment. Everything so far indicates that Apple will keep the same design but with significant improvements rather than making sweeping changes.

If other rumors and renderings are to be believed, it will still be a square design with a rounded display like its predecessors. So far, no unusual changes like a round display are to be expected.

A thinner design is more likely – but it won’t be significantly thinner.

Apple Watch Series 10 may not work with older straps

A leaker continued the band sentiment, saying in December that “the next-generation Apple Watch's connectors have been fully developed.” It also claimed that old bands wouldn't work with the new Apple Watch.

The leaker also insisted that the leak was “100% accurate,” which doesn’t exactly inspire confidence.

The mechanism for Apple Watch straps could change with the Series 10

The leaker did not elaborate on the claim or cite sources, but its hitherto sketchy accuracy included a correct claim about FineWoven bands prior to launch.

Considering the band's previous claims, it seems quite plausible that something will happen to the band's fasteners.

There is no obvious explanation for how this so-called magnetic tape system works.

Apple has explored new uses for magnets in its Apple Watch bands in patents, such as one that converts into a protective case. In a 2021 filing, Apple presented more than 50 drawings explaining how magnets could be used to securely connect.

Apple Watch Series 10 could save power thanks to better display

The Apple Watch already has systems to minimize battery consumption. The low power consumption and adjustable refresh rate allow the user to keep the display always on.

In addition, there is even a low power mode that reduces usage to the essential elements.

In April 2024, it was reported that Apple will update the display again to make it even more energy efficient. According to the report, the OLED display will use a new low-temperature polycrystalline oxide (LTPO) thin-film transistor (TFT) technology.

LTPO-TFT is already used in the Apple Watch display, but only for some switching TFTs within the panel. Older LTPS is now also used for other switching TFTs and driver TFTs.

The new display uses LTPO on more TFTs, including the driver TFTs. LTPS is still used, but only on all remaining TFTs and circuits outside the visible pixel area.

Apple Watch Series 10 could be thinner and larger or possibly thicker

According to two reports in June, Apple will make its Apple Watch thinner, following the trend pushed by the iPad Pro refresh.

It has been suggested that the Apple Watch will be made thinner as Apple introduces a new class of hardware that is intended to be the “thinnest and lightest” in its category.

To a certain extent, Apple has been pursuing the whole thin and light theme for years. This could be an even bigger push to go even thinner and lighter than ever before.

The sensor array is still located on the back of the Apple Watch Series 10.

In June, an analyst said that the Apple Watch's major redesign would not only make it thinner, but also larger.

The existing sizes of the Apple Watch start at 41 mm and go up to 45 mm. The Series 10 will start at 45 mm, with the larger size set to be 49 mm.

Testing of the 3D printed components reportedly went well and could impact future versions of the Apple Watch.

The screen of the Apple Watch X could be larger than that of an Apple Watch Ultra

At the end of June, the traditional leak of CAD designs and renderings occurred. Thanks to a 3D representation, these give an impression of what the new models could look like.

The renders released on June 26 look quite familiar to those who already use an Apple Watch. However, the display on the render is much larger than normal, with the body only slightly larger than the Series 9.

You may notice that the Apple Watch Series 10 has a larger screen than the Series 9.

This would give the impression of a larger display with thinner bezels. This screen would be 50.8mm, slightly larger than the 49mm Apple Watch Ultra.

The renderings also refuted other rumors that the Apple Watch Series X would be thinner. In the CAD image, the thickness is 11.6mm, more than the 10.7mm of the Series 9 and less than the 14.4mm of the Ultra.

A change of about a millimeter may not seem like much, and in most cases it isn't. But for an object you wear on your wrist every day, every dimensional change counts.

While a thicker unit wouldn't be the best outcome for the Apple Watch Series 10 or Series X, it would at least create more room inside for other components. Even a few extra millimeters of space could result in a larger battery cell, further improving battery life.

More time on the wrist is always good for a watch. For the next Apple Watch, if it does happen, it will certainly be a beneficial change, whether it achieves this through a larger physical battery or smarter usage.
