The key design differences between the Garmin Enduro 2 and Enduro 3 are:
Weight
- The Enduro 3 weighs 63g, which is 7g lighter than the 70g Enduro 2[1][2][4][7].- This weight reduction is achieved by switching the titanium backplate of the Enduro 2 for a plastic rear in the Enduro 3[4][6][7].
Thickness
- The Enduro 3 is slightly thicker at 15.7mm compared to the 15.6mm of the Enduro 2[2].Solar Lens
- The Enduro 3 has a thicker black solar ring around the outside of the lens[4].- It also removes the transparent solar panel across the surface of the display, increasing visibility[4].
Size
- Both watches have a 1.4-inch screen and come in a single 51mm case size[1][2][4].In summary, the Enduro 3 is lighter, has a thicker solar ring, and removes the transparent solar panel compared to the Enduro 2, while being slightly thicker and maintaining the same 51mm case size. The switch to a plastic rear helps reduce the weight of the Enduro 3.
