Which one fits you
On wrists narrower than about 54mm, the Forerunner 165 Music is the safer pick — it stays proportionate down to roughly 45mm, where the Fenix 7X Pro Solar Edition No Wi-Fi starts to hang over the edge. Above 54mm both sit cleanly, and the Fenix 7X Pro Solar Edition No Wi-Fi gives you more presence.
The Fenix 7X Pro Solar Edition No Wi-Fi wears larger than the Forerunner 165 Music (51mm vs 43mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Forerunner 165 Music is the slimmer of the two (11.6mm vs 14.9mm), so it slides under a cuff more easily.
On the wrist the Forerunner 165 Music feels lighter (39g vs 96g, case only).
The Fenix 7X Pro Solar Edition No Wi-Fi is thinner than 83% of the 51mm watches we track and the Forerunner 165 Music than 86% of the 43mm ones — so both wear flatter than their widths suggest.
The Fenix 7X Pro Solar Edition No Wi-Fi is 8mm wider, 8mm longer, 3.3mm thicker and 57g heavier than the Forerunner 165 Music. Both are circular.

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 51.0mm · Lug-to-lug 51.0mm · Thickness 14.9mm · 96g
Sweet Spot
51mm on a 55mm wrist
Across the wrist it works — 2.0mm spare each side — but a tall watch on this wrist. Fine over a sleeve, awkward under one.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 51mm.
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.

- Across the wrist2.0mm spare each side
Fills the wrist without reaching the edge.
- Off the wrist14.9mm off the skin
A tall watch on this wrist. Fine over a sleeve, awkward under one. (14.9mm case, back against the skin)
- How it seats~8.8mm under the rim
Wide enough that the edge of the case back lifts clear of the skin.
- Weight on the wrist96g
Substantial without being a burden — the usual weight of a steel watch on a wrist this size. (1.7g per mm of wrist)

Case 43.0mm · Lug-to-lug 43.0mm · Thickness 11.6mm · 39g
Balanced Fit
43mm 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 43mm, 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.

Light enough to forget you have it on. (0.7g per mm of wrist)
