Does the X fit your wrist?

Drag the slider to your wrist width and see the X overlaid at true scale. Lug-to-lug — not case diameter — decides whether a watch overhangs your wrist.

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.

The lugs run 0.2mm past each edge of your wrist — this is a size too big.

On a 55mm wrist the sweet spot is 4753mm lug to lug. This one is 55.4mm — look a size down.

Worn about 15mm further up your forearm it would clear — the arm is roughly 55.4mm across there.

How to Measure

Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.

  1. 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. 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.

Against one you know

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.

  • No published thickness, so there is nothing to say about how far it stands off the wrist.

  • Across the wrist0.2mm over each side

    The lug tips reach past the flat of your wrist and sit on the slope.

  • How it seats~19.8mm under the rim

    The case is as wide as the flat of your wrist, so it rests on the curve and will rock.

    Light enough to forget you have it on. (0.9g per mm of wrist)

X — Frequently Asked Questions

Will the Amazfit X fit my wrist?

How long does the Amazfit X battery last?

How does the Amazfit X battery compare with other Amazfit watches?

At 7 days in everyday use it ranks #46 of the 54 Amazfit watches in our database — below the middle of the range. The full ranking, including GPS and power-saving figures, is on our Amazfit battery life comparison.

What other watches are the same size as the Amazfit X?

Huawei TalkBand B6, Omega Constellation Automatic 36 Stainless Steel / Red Gold / Beijing Olympics 2008, Tissot Bellflower Square Yellow Gold / Diamond / Bracelet all sit within half a millimetre of the Amazfit X's 22.6mm case, so they cover the same amount of wrist.

What is the lug-to-lug of the Amazfit X?

55.4mm, against a 22.6mm case width. Lug-to-lug is the measurement that decides overhang: if it exceeds the flat width of your wrist, the lugs sit past the edge no matter how modest the case diameter looks.
