Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 48mm, the Active 2 is the safer pick — it stays proportionate down to roughly 46mm, where the GTR 4 Limited Edition starts to hang over the edge. Above 48mm both sit cleanly, and the GTR 4 Limited Edition gives you more presence.
The GTR 4 Limited Edition wears larger than the Active 2 (46mm vs 43.9mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Active 2 is the slimmer of the two (9.9mm vs 11.2mm), so it slides under a cuff more easily.
On the wrist the Active 2 feels lighter (29.5g vs 49g, case only).
The Active 2 is thinner than 99% of the 44mm watches we track and the GTR 4 Limited Edition than 84% of the 46mm ones — so both wear flatter than their widths suggest.
The GTR 4 Limited Edition is 2.1mm wider, 2.1mm longer, 1.3mm thicker and 19.5g heavier than the Active 2. Both are circular.
