Design, Display and Build

Garmin Forerunner 745 and Forerunner 945 - design and build

The design and build of a sports watch play a significant role in its usability and comfort during activities. In this aspect, both the Garmin Forerunner 745 and Forerunner 945 share a common foundation.

They feature cases made of glass fibre-reinforced polymer, a material known for its durability and lightweight properties. The flexible silicone straps not only contribute to the watches’ overall comfort but also ensure a secure fit during various physical activities.

When it comes to the display, both models are equipped with a vibrant 1.2-inch transflective memory-in-pixel (MIP) display.

This display, with a resolution of 240 x 240 pixels, is designed to be visible even in direct sunlight, providing users with clear and crisp information at a glance. Additionally, the Corning Gorilla Glass 3 DX protects the display, adding a layer of toughness to withstand the rigours of outdoor and athletic use.

Despite these similarities, there are subtle differences in dimensions. The Forerunner 945 is slightly larger with dimensions of 47 x 47 x 13.7 mm compared to the Forerunner 745’s more compact 43.8 x 43.8 x 13.3 mm size.

Users should carefully assess their storage needs and consider whether the additional space offered by the Forerunner 945 is worth the potentially higher cost.
