Garmin Epix Pro (Gen 2) vs Oppo Watch S

Garmin Epix Pro (Gen 2)

Bright, vivid AMOLED — the Epix Pro's defining feature versus the MIP-screened Fenix 7 Pro. Always-on display. Sapphire crystal on Sapphire editions.

• Bright, crisp AMOLED display — Engadget: 'a vivid picture without drawing too much battery life.'
• AMOLED is the Epix's defining choice — the vivid alternative to the MIP-screened Fenix 7 Pro.
• AMOLED draws more power than MIP — Notebookcheck notes MIP 'is a more power-efficient technology that thrives in direct sunlight.'
• Always-on display supported — vivid and readable, with battery cost the Epix's large cell absorbs.
• Sapphire crystal on Sapphire editions — highly scratch-resistant for the higher trim levels.

Oppo Watch S

A 1.46-inch round AMOLED at 464 x 464 (317 ppi). It can hit a brilliant 3,000-nit peak — but only automatically, in Oppo's workout modes under strong sunlight. In everyday use it's capped at 600 nits, with a 1,500-nit high-brightness mode.

• 1.46-inch round AMOLED, 464 x 464 at 317 ppi — sharp and vibrant, with Splash Touch that keeps the screen usable when wet.
• The 3,000-nit peak is genuinely bright — but it only activates automatically in Oppo's workout modes when the watch detects strong sunlight.
• Everyday brightness is capped at 600 nits, with a 1,500-nit high-brightness mode — OPTechWithAskar notes that at the typical 600 nits 'this is just a normal good display.'
• In bright outdoor workouts the screen is excellent — you can read pace and heart rate without the wrist-tilt dance.

Garmin Epix Pro (Gen 2)

Elevate Gen 5 optical HR with skin temperature, SpO2, HRV Status, Body Battery, sleep tracking, Morning Report. Garmin's latest sensor generation; ECG added via update.

• Elevate Gen 5 optical HR sensor — Garmin's latest HR generation, an upgrade over earlier Garmin watches.
• Skin temperature sensing — built into the Gen 5 sensor for overnight temperature tracking.
• HRV Status + Body Battery + sleep tracking + Morning Report — Garmin's full wellness + recovery analytics.
• SpO2 (pulse ox) — on-demand and continuous; useful for altitude acclimatization on mountain adventures.
• Optical HR is reliable for steady-state; like all wrist optical HR, less accurate than a chest strap for intervals.

Oppo Watch S

For a budget watch the Oppo Watch S carries a serious sensor array — an 8-channel optical heart-rate sensor, a 16-channel SpO2 sensor, ECG electrodes and a skin-temperature sensor — anchored by a 60-second check that reads around 14 health indicators at once. ECG availability depends on regional certification.

• A serious sensor array — an 8-channel optical heart-rate sensor, a 16-channel optical SpO2 sensor, ECG electrodes and a wrist-temperature sensor.
• A 60-second health check measures around 14 indicators — heart rate, ECG, SpO2, vascular elasticity and more — in a single reading.
• On-demand ECG via a side-button electrode takes about 30 seconds — Oppo's ECG is certified as a class 2 medical device in China and in around 30 countries.
• ECG availability is region-dependent — it may be disabled depending on local certification where you buy the watch.
• Day-to-day it does continuous heart-rate monitoring with high/low alerts, all-day SpO2 and wrist-temperature trends, plus sleep stages and a sleep score.

Garmin Epix Pro (Gen 2)

Garmin's deepest training-science suite — Endurance Score, Hill Score, Training Readiness, Acute/Chronic Load, daily suggested workouts, full multisport + triathlon modes. The serious-athlete benchmark.

• Endurance Score + Hill Score — advanced training metrics that quantify endurance fitness and climbing ability.
• Training Readiness + Acute/Chronic Load — science-backed daily training guidance.
• TechRadar ran a marathon with the Epix Pro and recommends it 'to every runner' — a genuine endorsement from race-day use.
• Full multisport + triathlon modes — open-water swim, brick workouts, transitions, plus 30+ sport profiles.
• 10 ATM water resistance — pool, open-water, and high-pressure swim activities supported.

Oppo Watch S

The Oppo Watch S covers 100+ workout modes with built-in GPS and an AI sports coach that gauges readiness from HRV and recent training load. It's a capable everyday fitness tracker — though there's little independent accuracy testing to confirm how it stacks up.

• 100+ workout modes with built-in GPS, plus swim tracking thanks to the 5 ATM water rating.
• Oppo bills it as featuring an AI sports coach that analyzes readiness from HRV during sleep and your last 7 days of workouts.
• In workout modes the display ramps to its 3,000-nit peak — a real advantage for reading stats outdoors mid-exercise.
• Independent accuracy testing is limited — there is far less hands-on GPS and heart-rate validation than for flagship rivals.

Garmin Epix Pro (Gen 2)

Multi-day to multi-week smartwatch battery depending on size; ~31 hours multi-band GPS on the 51mm. Strong for an AMOLED watch — but a MIP Fenix lasts longer.

• Multi-day to multi-week smartwatch battery — up to ~16 days on the 51mm, less on the 42mm. Strong for an AMOLED watch.
• ~31 hours multi-band GPS on the 51mm — supports ultra-endurance and multi-day adventure tracking.
• Battery scales with size — the 42mm trades endurance for compactness; the 51mm maximizes runtime.
• A MIP Fenix 7 Pro lasts longer — the AMOLED panel is the Epix's battery trade-off.
• Proprietary Garmin USB-C charging cable — no solar charging (solar is Fenix-only).

Oppo Watch S

The Oppo Watch S's strongest card. Oppo rates the 330mAh battery at up to 10 days maximum, 7 days typical and about 4 days with the always-on display on — and fast charging adds a full day in 10 minutes, with a complete charge in roughly 75-90 minutes.

• Oppo rates the battery at up to 10 days maximum, 7 days typical, and about 4 days with the always-on display enabled.
• The Tech Shed confirms about 7 days for an active user doing regular GPS workouts, with the headline 10-day figure reserved for lighter use.
• With the always-on display on, real-world life drops to around 4 days — still competitive with most smartwatch rivals.
• Fast charging is excellent — a 10-minute top-up returns a full day of use.
• A full 0-100% charge takes roughly 75-90 minutes via the magnetic pin charger.

Garmin Epix Pro (Gen 2)

Garmin OS + Garmin Connect + Connect IQ store. Garmin Pay. Works with iOS + Android. Frequent firmware updates. No Wear OS app catalog.

• Garmin OS + Connect IQ store — apps, watch faces, data fields; a mature ecosystem.
• Garmin Connect app — universally praised for training-analytics depth, frequently criticized for app-UI polish.
• Frequent firmware updates — Garmin continues adding features to the Epix Pro years after launch.
• Works with both iOS and Android — cross-platform, unlike Apple Watch or Galaxy Watch.
• Garmin Pay — contactless payments via NFC.

Oppo Watch S

The Oppo Watch S runs ColorOS Watch 7.1 on a power-efficient BES2800BP chip with 4GB of storage — not Wear OS. That choice is the reason the battery lasts a week, but it also means no Google Play app store and a simpler, more limited software experience.

• It runs ColorOS Watch 7.1 — a power-efficient platform that is the direct reason the battery lasts a week, not Wear OS.
• The trade-off is a simpler experience — there's no Google Play app store, so third-party app support is far more limited than on Wear OS.
• A power-efficient BES2800BP processor with 4GB of eMMC storage keeps the lightweight OS running smoothly.
• The companion health app works with both Android and iPhone — you don't need to own an Oppo phone to use the watch.

Garmin Epix Pro (Gen 2)

10 ATM water resistance + MIL-STD-810 thermal/shock/water testing. Titanium bezel + Sapphire crystal (Sapphire editions). Built for serious outdoor and expedition abuse.

• 10 ATM (100m) water resistance — pool, open-water, and high-pressure swim activities.
• MIL-STD-810 tested — thermal, shock, and water resistance for expedition use.
• Titanium bezel + Sapphire crystal (Sapphire editions) — premium, scratch-resistant adventure construction.
• Built for serious outdoor athletes — Engadget frames the Pro series as 'for serious explorers.'

Oppo Watch S

The Oppo Watch S is rated 5 ATM plus IP68 (and IP69), with Splash Touch that keeps the screen usable when wet. It's fine for swimming and everyday water — but Oppo specifically warns against hot showers, saunas and diving.

• 5 ATM water resistance plus IP68 and IP69 dust and water ratings — rated for swimming and everyday water exposure.
• Splash Touch keeps the touchscreen usable even when the watch is wet — handy after a swim or in the rain.
• Oppo specifically warns it's not meant for hot showers, saunas, hot springs or diving — and notes water resistance can reduce over time.

Garmin Epix Pro (Gen 2)

Multi-band (dual-frequency) GPS, full-color TopoActive maps, NFC for Garmin Pay, Bluetooth, ANT+, Wi-Fi. No LTE.

• Multi-band (dual-frequency) GPS — accurate tracking in urban canyons, dense forest, and deep valleys.
• Full-color TopoActive maps — Engadget notes the Pro series brings 'mapping upgrades'; on-watch turn-by-turn navigation.
• ANT+ + Bluetooth — pair chest straps, footpods, power meters, and cycling sensors.
• NFC for Garmin Pay + Wi-Fi for sync.
• No LTE — phone required for connectivity; no standalone calls or texts.

Oppo Watch S

Built-in GPS, Bluetooth, Wi-Fi and NFC cover the everyday essentials. There's no cellular model, so the Oppo Watch S relies on a paired phone for connectivity.

• Built-in GPS, Bluetooth, Wi-Fi and NFC — the standard everyday connectivity set.
• There's no cellular model — the Oppo Watch S relies on a paired phone for connectivity and can't go fully standalone.
• NFC supports contactless payments where the service is available.

Garmin Epix Pro (Gen 2)

$899-$1099+ launch. The AMOLED flagship multisport tier. Competes with the MIP Fenix 7 Pro, the Apple Watch Ultra, and the Coros Apex Pro. Ages well and discounts over time.

• $899-$1099+ launch — a genuine four-figure watch in Sapphire trims. Engadget: 'high-end smartwatches for explorers with deep pockets.'
• Discounts well over time — TechRadar noted the Epix Pro 'just hit half price'; Android Central tracked it to its lowest price ever.
• vs Fenix 7 Pro: same features, different displays — AMOLED (Epix, vivid) vs MIP (Fenix, longer battery + better in direct sun).
• Garmin watches age very well — Wired: 'even though Garmin watches are costly, they age very well.'
• Best for: serious runners, triathletes, and outdoor athletes who want Garmin's deepest training tools with a vivid AMOLED screen, full maps, and a flashlight — and can justify the four-figure price.

Oppo Watch S

The Oppo Watch S launched at around $399 NZD (roughly $230 USD) and is not officially sold in the US. For the price it's a strong value — week-long battery, ECG, a premium-feeling build — as long as you accept the simpler ColorOS platform.

• The Tech Shed's verdict: 'the Oppo Watch S is one of the best value smartwatches I've ever tested.'
• It launched at around $399 NZD — roughly $230 USD — undercutting flagship smartwatches significantly.
• It's a niche device — Oppo doesn't officially sell wearables in the US, so availability and support are limited there.
• FutureFive frames it well — it focuses on design, health tracking and battery life rather than software complexity.
• Best for: anyone who wants a featherweight, week-lasting health smartwatch at a budget price and doesn't need a deep app ecosystem.
