It has incredible features and works as a fitness tracker, health monitor, and personal assistant.

The watch basically used Bluetooth 5.0 for connectivity. If you are out of range then the second thing it uses is Wi-Fi (802.11b/g/n 2.4GHz and 5GHz). If everything fails then it uses the cellular models of Series 7 45mm to help you stay connected using LTE. Once you have followed the simple steps to connect your watch with a Compatible iDevice then you may leave your device out of reach and control everything from your wrist.

The Smartwatch has a Built-in rechargeable lithium-ion battery with Up to 18 hours of standby timing. With its fast-charging USB-C magnetic cable, It takes around 45 minutes to 1 hour for Full charging. However, this fast charging capability comes with all Apple smartwatches.

Screen Size and Display

One of the best features I personally love about this device is the Always-On Retina LTPO OLED display With 1,000 nits brightness. The Apple series 7 display is slightly bigger in size as compared to previous models. The Series 7 display size reduces the borders by 40% and has more screen area than both Series 6 and Series 3.

It has a 1,143 sq mm display area with 396×484 pixels resolution. The front glass curves over the sides of the case and is made of Sapphire crustal. One thing I would like to highlight here is Apple series 7 smartwatch also has shrunk Bazel and claims that the front crystal is made of sapphire crystal is the most crack-resistant material yet.

The right side of the watch is equipped with a digital crown and a multi-purpose button. The microphone hole is in between these two functional buttons. You can easily spot the single wide cut-out for the speaker on the left side of the watch.


Apple Series 7 45 mm delivers lightning-fast performance incredibly smooth and is responsive to use because of its 64-bit dual-core processor. The watch also supports dual-band Wi-Fi, Apple’s U1 chip, and ultra-wideband antennas. This feature keeps you connected even when you’re away from your phone, and the U1 Chip (Ultra Wideband) helps you locate your Apple Watch quickly and accurately.

Dust and Water Resistance of Apple watches

Apple claims that Apple Watch Series 7 and later are rated IP6X dust resistant. However, It is water resistant up to 50m. Apple watch series 7 45mm and all other models are water resistant, but not waterproof. For instance, It is okay to wear it during activities such as exercise (exposure to sweat is OK), walking in the rain, and washing your hands. However, the Classic Buckle, Leather Loop, Modern Buckle, Milanese, and Link Bracelet Bands aren’t water resistant. visit the Apple Official site to learn more about the Apple Watch’s water resistance.

GPS capabilities

Apple Series 7 GPS tracks your location and also provides real-time information about your surroundings. In addition, the GLONASS, Galileo, QZSS, and BeiDou help you to stay connected and navigate your way with ease anywhere in the world.

Cellular Features

The Apple series 7 45mm cellular + GPS model has excellent cellular features to help you stay connected while gyming. It not only gives you the freedom to take or make calls and respond to text messages but also offers easy access to all kinds of apps like Calculator, Stopwatch, Timer, etc. The new QWERTY keyboard in series 7 lets you tap or slide from letter to letter with QuickPath. It uses machine learning to predict the word you’re typing. Use Scribble to write letters on your screen and compose a text or email. The larger display makes it faster and easier for all fingers.

It also installs the compatible apps that are already installed on your Apple device. So you can easily control everything from your wrist. With Apple virtual assistant Siri, you can easily make calls, send texts, and set reminders without having your phone in hand. it can be summoned either by long pressing the digital crown and saying “Hello Siri ” or Raise the watch near to your face and speaking without pressing any button.

Fitness capabilities

One of the reasons why I personally thought to invest in an Apple smartwatch is its Fitness capabilities. If you want to set your style quotient high without compromising on your Fitness goals then I would suggest you invest in the Apple watch series 7 45mm. The watch accurately provides you with data based on your physical activities whether running, swimming, or cycling.

I wore the watch on my route to the office to check the distance covered and it showed 2.5 km which was very precise and accurate. It also accurately reported the steps taken. The watch provides you with your exercise, movement, and standing goals on a daily basis.

Apple Watch Series 7 can be used for tracking different activities like strength training, HIIT, cycling, walking, and even swimming, etc. It is your perfect gyming and fitness partner. It not only tracks your heart rate but also quickly detects the changes. If you want you can cross-check the heart rate reading with a readout from the treadmill. I did the same thing just to check if my watch is accurate or not. Surprisingly the readout on my watcha dn treadmills was the same. From these experimental observations, it is not wrong to claim that Apple Smartwatch is a highly accurate and perfect fitness partner.

The watch also tracks blood oxygen saturation in normal conditions and even while you are asleep. It can also record ECG in 30 seconds and saves the readings on your iDevice. This allows you to share the details with your health advisor. The watch can check for signs of atrial fibrillation also. Another great health feature is sleep tracking. It tracks your sleep patterns and helps you create a schedule and a bedtime routine. It also tracks your respiratory rate while you’re sleeping.

The other exciting feature of the Apple smartwatch is an Accelerometer of up to 32 g-forces with Fall Detection and Crash Detection. it also auto-connects you with emergency services in case of an accident or emergency situation.

The verdict

Overall Apple Watch Series 7 45mm smartwatch comes with an array of feature that makes life easier and more convenient. It helps you keep your fitness goals on top and makes your workout sessions motivating. With its incredible features like dust resistance, water resistance, fall and clash detection, Heart rate sensors, and many other activity trackers this watch is definitely worth considering.
