Which one fits you

Both need much the same wrist — roughly 45–63mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.

The Active 2 wears larger than the GTR Mini (43.9mm vs 42.8mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The GTR Mini is the slimmer of the two (9.25mm vs 9.9mm), so it slides under a cuff more easily.

On the wrist the Active 2 feels lighter (29.5g vs 36.2g, case only).

The Active 2 is thinner than 99% of the 44mm watches we track and the GTR Mini than 99% of the 43mm ones — so both wear flatter than their widths suggest.

The Active 2 is 1.1mm wider, 1.1mm longer, 0.7mm thicker and 6.7g lighter than the GTR Mini. Both are circular.

Watch Fit Tool

For sports watches, lug-to-lug (L2L) is what matters most — it decides whether a watch overhangs your wrist. Bulky is fine; overhang is not.

Comfortably inside the edges of your wrist, and it seats and sits low enough to wear without thinking about it.

On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 43.9mm, so you could go bigger.

How to Measure

Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.

  1. 1. Flat width — arm flat on a table, palm up. Measure straight across the top of the wrist, bone to bone, ignoring the curve down the sides.
  2. 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
