The exciting Apple Watch 7 could be unveiled at an Apple event on Tuesday, September 14 Along with a new flagship iPhone and possibly an iPad and refreshed AirPods, Apple could unveil its latest smartwatch with a modern design, improved specs, and more

This is because rumors of an Apple Watch 7 have been ramping up in recent weeks From information on the production line to multiple mentions of extended battery life for the Apple Watch 7, we have a good idea of what the next generation will feature

Of course, there are some details that we won't know until the official announcement, such as the price of the Apple Watch 7 and the health upgrades that will reportedly be included in the Apple Watch 7

But whether you're looking to upgrade your current Apple Watch or are simply interested in how the best smartwatch is going to get even better, you need to get up to speed on the most important Apple Watch 7 rumors

Here are the three major Apple Watch 7 upgrades we expect to see

It is almost certain that the Apple Watch 7 will look different from previous Apple Watch models; the look of the Apple Watch has changed little since the first model debuted in 2016, but the iconic screw is a newer, flatter edge iPhone, which could be tweaked to follow the design language of the iPhone 12

Rumors of a flat-sided Apple Watch surfaced earlier this year when leaker Jon Prosser shared a series of renderings At the time, Prosser said his source may have passed along information about another future Apple Watch, not the Apple Watch 7 However, another rendering released in August revealed plans for a redesign: a purportedly leaked CAD file shared by 91Mobiles teased a flat Apple Watch 7

In addition to a fresher look, the Apple Watch 7 could also be larger; the Apple Watch will reportedly grow in size from 40mm and 44mm to 41mm and 45mm This may not sound like a significant change, but millimeters make a difference on the wrist

Current Apple Watch bands may not fit the Apple Watch 7, but the increased size is a big step toward making Apple's smartwatch a more independent device

Apple Watch internals may also be due for an upgrade; according to Bloomberg, the Apple Watch 7 will feature an "updated ultra-wideband (UWB) feature" Apple included a U1 chip in last year's Apple Watch 6, and the next model may improve this chip or the chip's role in the Apple Watch's wireless communications

The company's interest in positioning technology gained momentum with the launch of the Apple AirTag key finder; as we have seen with AirTag, UWB radios provide accurate position and spatial awareness, allowing compatible devices to determine their exact location relative to other devices in the vicinity

The watchOS 8 software in the Apple Watch 7 also adds a "Find My" app for locating other Apple devices It also adds support for digital keys, allowing users to enter cars, hotel rooms, and other places with a wrist-based virtual wallet Given the pace of improvements and new features in Apple's U1 chip, connectivity features and functionality are expected to be enhanced in the next generation of smartwatches

Several Apple sources have suggested that the next refreshed model will have a much improved battery compared to the previous generation; of all the Apple Watch 7 rumors, this is the one we are most excited about

No longer is the Apple Watch rated for 18 hours, leaker Max Weinbach claims on his Pineleaks Twitter account In a lengthy thread shared recently, Weinbach made claims about the iPhone 13, AirPods 3, and yes, the Apple Watch 7 Apparently, Apple's flagship smartwatch will have "improved battery life for the first time 0]

Earlier this year, Apple analyst Ming-Chi Kuo also mentioned rumors of a double-sided system-in-package (SiP) that would free up space inside the Apple Watch, and he mentioned improved battery life

It is hard to say for sure what the improved battery life will mean for Apple, but we expect it to add a couple more hours to the familiar 18-hour estimate days, but we don't expect it to last more than that
