It is highly likely to be unveiled alongside the iPhone 6C at Apple's March event.

Building on the success of the first-generation Apple Watch, what will the second-generation product look like?

The most anticipated aspect of the second-generation Apple Watch is the improvement in battery capacity. This is because criticism regarding the Apple Watch's insufficient battery capacity has persisted since its initial launch. Additionally, a recent report by DigiEco (KT Economic & Management Research Institute) stated that while Apple announced the provision of FaceTime voice calling features with the release of watchOS 2.0, the second-generation product is expected to support video calls along with voice.

If video calls are supported, taking photos and videos is also possible.

If video calling is supported, it implies that a camera is included, suggesting that taking photos and recording videos will also be possible. The Apple Watch was released in a total of three models: a low-cost sports model, stainless steel, and a luxury edition. According to rumors, there is talk of adding a new lineup, while others predict that they will be integrated into a single model.

The Apple Watch, which was released last April, was the hottest IT device of 2015 and received a lot of attention from users and the industry. The first-generation Apple Watch, which recorded lower-than-expected sales in the early stages of its launch, gradually dominated the smartwatch market with its stylish design and various features, and market research firm IDC predicted that a total of 13 million units would be sold by the end of 2015.

Investment firm FBR Capital Markets forecasts that approximately 6 million units will be sold in the fourth quarter alone, driven by the special demand during the Christmas and year-end holiday season. According to recently released Securities and Exchange Commission (SEC) data, Apple generated nearly $1.7 billion in revenue from Apple Watch sales within just five months of its launch. Horace Dediu, an analyst well-versed in Apple, projected that 21 million units would be sold within the first year of release. Based on an average price of $400, revenue from the Apple Watch is expected to reach a staggering $8.4 billion by April 2016.

The Apple Watch took the overwhelming first place in the overall smartwatch market with a 61.3% share, far exceeding the initial sales forecast of 11 million units. Immediately after launch, the app ecosystem, which was initially lacking, also steadily expanded, with over 15,000 apps registered on the App Store—a fivefold increase over the past eight months.

Accordingly, companies involved in Apple Watch development and various experts believe that Apple has already opened the second-generation watch.
Rumors are constantly circulating that it is in the works. The Apple specialist community 9to5Mac reported that Apple plans to announce the Apple Watch 2 at a new product launch event in March 2016.

Overseas media reported that the new Apple Watch would be unveiled at an event in March and officially launched in April. According to media reports, Apple is expected to announce the iPhone 6C with a 4-inch display along with the Apple Watch 2.

Evaluations are mixed regarding the differentiation of the content.

With high expectations for the second-generation Apple Watch leading to significant pent-up demand, opinions have been raised that usability and killer apps need to be addressed, along with the shortcomings of the hardware.

Despite high device sales, evaluations are mixed regarding the differentiation of content, which is the most important aspect for smart devices. According to the Mobile Life Research Center at Stockholm University in Sweden, the most used app on the Apple Watch was found to be 'Watch Faces,' and the second most used feature was 'Notifications.' These results are also the reason why the Apple Watch is receiving criticism for failing to go beyond traditional watch functions.

Critics point out that the iPhone demonstrated innovation distinct from existing smartphones by delivering an experience that went beyond a 'mobile phone,' whereas the Apple Watch does not exhibit such advantages.

Finally, the report stated that, realistically, innovation in smartwatches is not easy, so it remains to be seen whether the second generation can maintain as much interest and viability as the first.

The report analyzed that while it is difficult to accurately predict the release date of the second-generation Apple Watch, the product is likely to be unveiled at an event in March 2016. It further noted that with new demand for the iPhone gradually declining, Apple needs a new breakthrough and is in a situation where it has no choice but to invest heavily in the second-generation Apple Watch for this purpose.
