Single-band GPS (no multi-band) — Venu X1 relies on standard single-frequency GPS. Accurate in open environments but can experience drift in urban canyons or under heavy tree cover.

No SatIQ technology — because the Venu X1 lacks multi-band GPS, it has no need for SatIQ's automatic management. Single-band GPS is always-on during tracked activities.

Open environment performance — for casual walks in open parks, running tracks, and countryside routes, the Venu X1's standard GPS remains adequately accurate for most users.

Simpler GPS experience — without multi-band, GPS behaviour is more consistent and predictable, though at the cost of peak accuracy in challenging conditions.

Square AMOLED display — box-shaped design inspired by the Apple Watch aesthetic. The square shape maximises usable screen area for data-dense Garmin watch faces.

Sapphire crystal glass — premium scratch-resistant material that is significantly harder than Gorilla Glass. Practically immune to surface scratches from everyday use. This is the headline hardware premium of the Venu X1.

390 × 390 px resolution — perfectly square pixel grid that aligns naturally with Garmin's grid-based data fields. The square form factor arguably displays more usable data at a glance.

AMOLED brightness — same AMOLED display technology as the Venu 4. Rich colours and deep blacks across both watches.

No ECG app support — the Venu X1 is not compatible with Garmin's ECG application. Users requiring on-demand heart rhythm readings will need to look at the Venu 4 or other Garmin models.

24/7 Heart Rate monitoring — same continuous optical heart rate capability as the Venu 4.

Pulse Ox (SpO₂) — same blood oxygen monitoring as the Venu 4.

Stress tracking & Body Battery — same HRV-based stress and Body Battery energy tracking as the Venu 4.

Advanced sleep tracking — same sleep stage coverage and Sleep Score as the Venu 4.

32GB internal storage — four times the storage of the Venu 4. Ample space for large offline music libraries, extensive maps, and Garmin Connect app data simultaneously.

Offline music — expanded capacity — 32GB can hold thousands of songs for phone-free listening on long runs, hikes, or workouts.

Maps support — expanded regions — significantly more space for downloading TopoActive maps across multiple regions and countries simultaneously without juggling storage.

Similar battery life — despite the larger square display and premium sapphire glass, the Venu X1 matches the Venu 4's battery life in comparable usage modes.

Square case design — Apple Watch-inspired form factor aimed at users crossing over from the iOS ecosystem. Dressier and more contemporary than traditional Garmin aesthetics.

5 ATM water rating (SWIM) — identical swim rating to the Venu 4. No difference in water sports capability between the two models.

Wi-Fi, Bluetooth, ANT+ — same full connectivity as the Venu 4. External sensor support via ANT+ is available on both models.
