Launched in 2015 to a surprised and curious audience, the Apple Watch is a smartwatch that connects and works in unity with the iPhone.

It has now evolved to have a plethora of health features and functions, ideal for doing what a watch always does but with health-tracking communication tools and more.

The Apple Watch is the most popular smartwatch in the world, and it is also known as the lucrative smart device that presides over its peers concerning sales volume and revenue generation.

This watch is a high-performance technology that has several features that make it an exceptional health and fitness-tracking wearable device.

Its Features

Built-in is a heart rate sensor, which measures your heartbeat throughout the day and tells you if all is going well. It also has an ECG app to produce a similar-to single-lead electrocardiogram, which can identify signs of atrial fibrillation or other heart conditions.

The watch also features a blood oxygen app that permits you to measure your blood oxygen levels as an indicator of health and wellness.

It can also help monitor:

  • Activity
  • Exercise
  • And sleep patterns…

Which in turn provides you with personalised coaching, awards, or even competitions that will encourage you towards what should be attained in general.

Cutting-Edge Emergency Sensors

Apple Watch also has the capability of knowing when you have fallen or even had a car crash and will call emergency services for you, as well as inform the people listed on your “in case of accident” details.

It also features an app for tracking the menstrual cycle to know more about your period and fertility.

The Apple Watch is also rich in a number of other features, which make it convenient and flexible. It is Apple Pay-ready; you can make payments by just tapping your wrist.

It can also receive notifications, make calls and send texts; it can run apps from your iPhone or independently. It has a digital crown, so navigating the small screen is much easier to use; there’s even Siri voice assistant for when you have various tasks ahead.

It also has several:

  • Watch faces

  • And band attachments that you can tailor to suit your taste.

Sales and Market Share

Based on Edison research, the Apple Watch cornered 95% of all smartwatches shipped in 2015 and generated around 60% of revenues for the entire market.

Fast-forward to last year, Apple sold about 232 million smartwatches in 2023, which was a slight decrease from 2022, when it sold 240 million units.

As the best smartwatch in the world, it is also recognised as a revolutionary device in the health and fitness industry.

Which Apple Watches are on the market?

The Series 9SE and the Ultra 2.

Currently, the Apple Watch is in Series 8. The first-generation model of the watch was released in 2015, and several models have been introduced after that, such as series-1,2,3… and so on.

The feature and function of each model comprises unique features and functional factors that make each one different in terms of its positioning requirements. Here is a brief overview of some of the key differences between the models:

Series 9

This is the company’s latest and most sophisticated watch, which was released in 2023. It is also 45 mm or 41 mm in either case size, made of aluminium or stainless steel with an Always-On Retina display that has up to 2000 nits brightness. It also runs on the new S9 SiP (System in Package) tech, making it faster and more powerful. There’s even a double tap gesture that you can use to switch between apps or functions now and


This is a cheaper version released in 2020. It has a 44mm or 40 mm aluminium case size, an always-on Retina display with up to 1000 nits of brightness and an S8 SiP, so it is ultrafast and efficient. You can have the blood oxygen app, ECG App, low cardio fitness notification like in the LTE models, and cycle tracking capability for women’s health.

Ultra 2

This is another 2023 model, which is rugged and capable. It has a 49mm titanium case size, an Always-On Retina display with up to 3000 nits of brightness, and S9 SiP that makes it even faster and more powerful for extra quick screen swipes, letting you see life tracking data wherever the app is—no launching required. You get ultra‑fast, on‑device Siri-powered health data access that enables users to tap into their historical data.


What started out to many as some kind of a gimmick that wouldn’t really catch on as a watch is too limited to be able to do too much more than tell the time and give you a heart rate now has some mind-blowing functions in there that has health enthusiasts queuing up for them.  The amount of features crammed into a little watch on your wrist is a testament to Apple and their innovation. These great functional tools can help people of all ages keep a good eye on their health and well-being.  With its market share, we can only see the Apple Watch getting stronger.
