How to Measure
1

Lay arm flat, palm up.

2

Measure the flat width across top of wrist.

Garmin Approach® S70 - 42 mm (010-02746-00)
Case: 42mmL2L: 42mmThick: 12.6mm
Balanced Fit6.5mm clearance. Comfortable everyday wear with room to spare.
Garmin tactix® 8 – 47 mm, AMOLED (010-03405-00)
Case: 47mmL2L: 47mmThick: 13.8mm
Sweet Spot4mm clearance. Perfect for sports watches - bold presence, no overhang.

The Garmin tactix® 8 – 47 mm, AMOLED wears larger than the Garmin Approach® S70 - 42 mm (47mm vs 42mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Garmin Approach® S70 - 42 mm is the slimmer of the two (12.6mm vs 13.8mm), so it slides under a cuff more easily.

On the wrist the Garmin Approach® S70 - 42 mm feels lighter (44g vs 73g, case only).
