- The 41mm is Cheaper
- The 45mm unit has a bigger display, but weighs a little more
The 41mm is cheaper than the 45mm. As you can see on the table above, the GPS-only model of the 41mm and 45mm aluminum model cost $399 and $479 respectively. The stainless steel is priced higher with the titanium material being the most expensive.
While the 45mm has a display size of 1.9 inches, the 41mm has a display size of 1.69 inches. This represents a 20% bigger display than Watch 6. And with a larger viewing area and a higher screen-to-body ratio, the 41mm is easy to read just like the 45mm. I own the 45mm aluminum/GPS unit, and I really love it’s wide display. It’s bold, yet still very compact (note I moderate-sized wrist).
Meanwhile, while the 41mm aluminum model weighs 32 grams, the 45mm aluminum model weighs 38.8 grams. In the same vein, 41mm and 45mm of stainless steel weighs 42.3 grams and 51.5 grams respectively. The stainless steel model is the heaviest, yet very lightweight.
Beyond these slight differences, the 41mm and 45mm sizes have the same features. Each of these two features fast charging that takes a 30% shorter time to charge when compared to it’s predecessor. Other features include the ability to track your ECG, stress, blood oxygen, and many more features.

Unlike the Watch 6 down to Watch 4 which are all available in 44mm and 40mm, the Watch 7 is available in 41 and 45mm. This signifies a drift from the norm that gives you a bigger size in a yet somewhat compact size.

41mm or 45mm: Which Size is Rigth For You?
With a wider and brighter display size as well as a higher screen-to-body ratio, the 41mm or 45mm can make a perfect choice for you. It’s no longer about display size since even the 41mm has a display size that allows you to see more at a glance in a very compact size.
Nevertheless, the 41mm size is recommended for individuals who have a slim wrist while we recommend the 45mm size for individuals who have a moderate to fat wrist size.
To get the best size, you want to use a meter rule to measure the width of your wrist, then compare it to the 41mm or 45mm width to know which is more suitable for you. But bear it in mind that each of these two has a large display size that allows you to see more at a glance although the 45mm size has a bigger display size.
