Which one fits you
On wrists narrower than about 49mm, the Active 2 is the safer pick — it stays proportionate down to roughly 46mm, where the Bip 6 starts to hang over the edge. Above 49mm both sit cleanly, and the Bip 6 gives you more presence.
The Active 2 wears larger than the Bip 6 (43.9mm vs 40.2mm 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 10.45mm), so it slides under a cuff more easily.
Among the 316 44mm watches we hold thickness for, the Active 2 is thinner than 99%, so it wears flatter than its width suggests.
The Bip 6 is middle-of-the-pack for thickness among the 530 40mm watches in the database.
The Active 2 is 3.7mm wider, 2.4mm shorter, 0.5mm thinner and 1.6g heavier than the Bip 6.

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.
Measure at the point where you wear your watch — typically just below the wrist bone.
Flat width — lay your arm on a table, palm facing up, and measure straight across the top of your wrist with a ruler. Bone to bone; do not follow the curve down the sides.
Around — wrap a tape measure snugly round the wrist. No tape? Wrap a strip of paper, mark the overlap and hold the strip against a ruler.
Width ≠ circumference. They are different numbers — around 170mm is about 64mm across — so set the toggle to whichever one you actually measured before you type it in.

Case 43.9mm · Lug-to-lug 43.9mm · Thickness 9.9mm · 30g
Balanced Fit
43.9mm on a 55mm wrist
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.
Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.
- 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. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. Typical figures, not this model’s own.
