Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 48mm, the Active is the safer pick — it stays proportionate down to roughly 38mm, 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 (46mm vs 42.36mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the Active feels lighter (27g vs 49g, case only).
The Active is thinner than 87% of the 42mm 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 3.6mm wider, 10.1mm longer, 0.4mm thicker and 22g heavier than the Active.
