41mm or 45mm – Which is Right Size For You?
As you can see from the tables above, the 41mm and 45mm have similar features except for the differences in dimension, weight, and battery life. The 45mm which is obviously bigger has a wider 1.4 inches display compared to 41mm that has a 1.2 inches display size. In other words, it easier to read complications on the 45mm model, but the 41mm model is more compact.
The 45mm also has a bigger battery capacity than the 41mm, as a result, it allows you to go longer from a single charge. I got about 2 days long battery life with the 45mm which is longer than about a day with the 41mm model. You should bear in mind that battery life will vary depending on your settings and usage.
The 45mm is also priced higher than the 41mm model because of the aforementioned differences.
So which should you buy? – I have the 45mm model, and I can say it’s not bulky nor heavy. It’s a better choice for men, while the 41mm model will make a better choice for women. Although, any of these two is a befitting choice for both men and women.
