Garmin Instinct 2 Solar vs Instinct 2S Solar
Size, specs & wrist fit compared
Which one fits you
Under 16 cm (6.3 in) round, the 45mm's lugs overhang and the 40mm's do not; the 40mm fills the wrist at 15–17 cm, the 45mm at 17–19 cm.
What else differs
- Battery: 28 days for the 45mm against 21 days for the 40mm in everyday use; 30 hours for the 45mm against 22 hours for the 40mm with GPS on.
Among the 40 smartwatches 40mm across that we hold thickness for, the Instinct 2S Solar is thicker than 90%, so it sits higher on the wrist than most of its size.
The Instinct 2 Solar is 5mm wider, 1.2mm thicker and 10g heavier than the Instinct 2S Solar.
