Which one fits you
On wrists narrower than about 51mm, the Watch GT 6 - 46mm is the safer pick — it stays proportionate down to roughly 48mm, where the Watch D2 starts to hang over the edge. Above 51mm both sit cleanly, and the Watch D2 gives you more presence.
The Watch GT 6 - 46mm wears larger than the Watch D2 (46mm vs 38mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Watch GT 6 - 46mm is the slimmer of the two (11mm vs 13.3mm), so it slides under a cuff more easily.
On the wrist the Watch D2 feels lighter (40g vs 51.3g, case only).
Among the 356 38mm watches we hold thickness for, the Watch D2 is thicker than 90% — it will sit high even though the case width reads modest.
Among the 211 46mm watches we hold thickness for, the Watch GT 6 - 46mm is thinner than 88%, so it wears flatter than its width suggests.
The Watch GT 6 - 46mm is 8mm wider, 2mm shorter, 2.3mm thinner and 11.3g heavier than the Watch D2.
