Size, specs & wrist fit compared

Which one fits you
Both need much the same wrist — roughly 49–68mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Balance 2 wears larger than the Bip 6 (47.4mm vs 40.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Bip 6 is the slimmer of the two (10.45mm vs 12.3mm), so it slides under a cuff more easily.
On the wrist the Bip 6 feels lighter (27.9g vs 43g, case only).
Among the 85 47mm watches we hold thickness for, the Balance 2 is thinner than 81%, 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 Balance 2 is 7.2mm wider, 1.1mm longer, 1.9mm thicker and 15.1g 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.

Sweet Spot
47.4mm on a 55mm wrist
Across the wrist it works — 3.8mm spare each side — but wide enough that the edge of the case back lifts clear of the skin.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 47.4mm.
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.

Balanced Fit
46.3mm 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 46.3mm, so you could go bigger.
