02Materials
Every surface, considered.
01
Titanium core
Machined from Grade 5 titanium and bead-blasted to a satin finish. The core curves with your wrist, so it sits flat through sleep and sprints alike.
02
Double-weave strap
Recycled nylon woven over an elastane core. It breathes in the heat, dries in about 20 minutes and keeps its shape for years.
03
Sapphire sensor window
A domed sapphire lens holds the optical array against the skin with gentle, even pressure, the single biggest factor in a clean signal.
04
MagLock clasp
Two titanium halves close with 40 newtons of magnetic hold and a precise mechanical key. On with one hand, never off by accident.
03Colorways
Three finishes. One standard.
Carbon Black
Black double-weave strap, DLC-coated titanium core and a signal-orange inner lining.
Signal Orange
High-visibility orange weave with a graphite titanium core, made for early starts and late finishes.
Stone Titanium
Warm stone weave with a bead-blasted natural titanium core and a tonal lining.
04Sizing
Find your fit.
- 1
Wrap a strip of paper around your wrist, just above the wrist bone where the band will sit.
- 2
Mark where the paper overlaps and measure the length in millimetres.
- 3
Choose the size whose range puts you closest to the middle. Between sizes, go smaller.
| Size | Wrist | Notes |
|---|---|---|
| 130 to 160 mm | Most wrists under 16 cm | |

06FAQ
Questions, answered.
Because the most useful data is the data you don't stare at. Without a display, the band is thinner, lighter, lasts up to 10 days and never pulls your attention mid-session. Live numbers stream to your phone when you want them, and silent haptic cues tell you when you drift out of your target zone.
No. Every metric, every insight, your complete history and full data export are included with the band. Software updates that add new features are free for the life of the product.
Double-tap the core and a short haptic pulse confirms the session has started. Runs, rides, swims, walks and strength sessions are also detected automatically, and you can start any of 90 activity types from the app.
In validation against chest-strap ECG, PACE Band measured heart rate within 1.8 bpm on average across 40 activity types and tracked overnight HRV with a 0.97 correlation. Accuracy can vary with fit, so wear the core snug, one finger above the wrist bone.
Yes. The band is rated 10 ATM and tracks pool and open-water swims, including distance, stroke rate and SWOLF. The woven strap dries in about 20 minutes.
Workouts and daily metrics sync to Apple Health, Health Connect, Strava and TrainingPeaks, and you can export your full history as CSV or FIT files at any time.
Exchanges are free within 60 days. Measure your wrist just above the bone with a strip of paper, then pick the size whose range puts you in the middle. Between sizes, choose the smaller one.
