Garmin Instinct 3 AMOLED

What Reviewers Agree On

The new AMOLED display is a genuine upgrade — bright, vibrant and high-resolution, readable in any lighting.
Classic Instinct toughness — MIL-STD-810 build, metal-reinforced bezel, 100m water resistance and a chemically-strengthened lens.
Excellent smartwatch battery life — up to 18 days on the 45mm and 24 days on the 50mm.
Multi-band (dual-frequency) GPS is highly accurate — testers found it tracking within tenths of a kilometre of an Apple Watch Ultra and reference apps.
Built-in LED flashlight on every Instinct 3 model — a genuinely useful outdoor feature.

Detailed Comparison

Battery & Charging

Garmin Instinct 3 AMOLED

Excellent for a smartwatch — Garmin rates up to 18 days on the 45mm and 24 days on the 50mm. Real-world results land lower with the always-on display and flashlight, but multi-day endurance is never in doubt. There is no wireless charging.

Rated up to 18 days (45mm) and 24 days (50mm) in smartwatch mode — about 7-9 days with the always-on display enabled.
The Run Testers got 9 days of general use on the 45mm AMOLED including 7 hours of GPS training and 2 hours of indoor cardio.
GPS endurance is strong — the 45mm AMOLED is rated about 23 hours of multi-band tracking, the larger Solar models far more.
Overnight drain is low — The Wearableist measured around 2% per night, and after 11.5 days the AMOLED still held about 60%.
No wireless charging — it charges via Garmin's proprietary cable, with a full charge in roughly an hour.

Deal Breakers

No on-watch maps — only breadcrumb navigation, a glaring omission at $449-$499 when cheaper rivals include full mapping.
It keeps the older Gen 4 heart-rate sensor — so no ECG and no skin-temperature sensing, unlike Garmin's newer Elevate 5 watches.
Heart-rate accuracy is middling — testers measured ~20 bpm deviations during hard interval workouts; a chest strap is recommended.
Value is questionable — DC Rainmaker felt the upgrade wasn't worth the asking price, and Garmin permanently cut the list price soon after launch.
No touchscreen — everything is driven by five physical buttons (a plus for some, a limitation for others).
No 40mm size — the smallest Instinct 3 AMOLED is 45mm, dropping the compact option the Instinct 2 offered.

OnePlus Watch 2R

What Reviewers Agree On

Class-leading Wear OS battery life — a dual-chipset (Snapdragon W5 Gen 1 + BES2700) design gives ~3-4 days of real use, far beyond Pixel/Galaxy Wear OS rivals
Genuinely fast charging for a smartwatch — roughly 0-100% in ~50-65 minutes and a 10-minute top-up for about a full day
Excellent value at ~$229 (often $175-200 on sale) — close to flagship functionality for a fraction of the price
Lightweight, comfortable aluminium build (~25% lighter than the Watch 2) with IP68 + 5ATM and standard 22mm straps
A clean, responsive Wear OS 4 experience with the liked 'Bubbles' app interface — better than its early reputation

Deal Breakers

Single-band GPS and a dimmer 1,000-nit (600-nit typical) screen versus the Watch 2's dual-frequency GPS and brighter rivals
Only ~2 years of software updates and no fall detection — short support for a long-life watch
Basic OHealth fitness/sleep tracking and slow (~8-10 min) auto workout detection — not for serious athletes
Panda Glass (not sapphire) build is more scratch/crack-prone than the steel OnePlus Watch 2
Large 47mm-class body and quiet speaker; no LTE and no rotating crown

OnePlus Watch 2R

The headline strength. The dual-chipset design makes this the longest-lasting Wear OS watch — 3-4 days real-world against OnePlus's 100h smart / 48h heavy / 12-day power-saving claims — and it recharges in about an hour.

OnePlus claims up to 100 hours in Smart Mode, 48 hours heavy use, and 12 days in power-saving mode from the 500mAh cell.
Real-world: ~3 days with the always-on display off and lift-to-wake — closer to 4 days light, not quite the 100h claim without battery-saver tweaks.
Hands-on: hit ~90 hours in Smart Mode with brightness near max before being forced into battery-saver — the longest battery life of any Wear OS watch tested.
Day test: 100% in the morning, a gym hour plus heavy Google Maps walking, and it still had ~62% the next morning.
Charging: 0-100% in roughly 50-65 minutes on the included charger, exactly as OnePlus claims; a 10-minute top-up gives about a full day's use.
Charging is via a magnetic 4-pin/Pogo dock with a removable USB-C cable — there is no wireless charging (despite some spec listings citing 7.5W wireless, which appears to be Watch 2 data).
Power-saving auto-engages at 10%; the secondary RTOS chip flattens drain so the watch keeps notifications and basics for days more.

Value vs Competition

Garmin Instinct 3 AMOLED

At $449.99 (45mm) and $499.99 (50mm), the Instinct 3 AMOLED sits in a crowded mid-range, and reviewers are split. It's a tough, gorgeous watch — but the missing maps and older sensors make rivals like a discounted Fenix 7 or the Amazfit T-Rex 3 Pro genuinely tempting.

$449.99 for the 45mm and $499.99 for the 50mm — and GearJunkie still calls it 'the answer' for a rugged outdoor smartwatch with exceptional battery.
the5krunner's reviewed verdict is blunt: the Instinct 3 AMOLED 'is not the best value for money,' though still 'a tough, good-looking watch.'
Chase the Summit notes a Fenix 7 with sapphire, mapping, music and a touchscreen can be found for $50 less than a 50mm Instinct 3.
Garmin permanently cut the list price soon after launch — DC Rainmaker notes that signals the original pricing was too high.
Best for: outdoor enthusiasts who want a tough, great-looking AMOLED adventure watch with multi-week battery and pinpoint GPS — and don't need maps.

OnePlus Watch 2R

At ~$229 (often $175-200 on sale) the 2R is widely called the best-value Wear OS watch — it delivers ~95% of flagship functionality and the platform's best battery, against a Watch 2 that costs more for steel and dual-frequency GPS.

The best budget Android watch tested at this price — frequently discounted a further $50.
Verdict: 'Hey, not half bad' — a genuinely good affordable Wear OS option.
At ~$229 it delivers roughly 95% of flagship-watch functionality (those cost 2-3x) with no significant compromises for everyday use.
Versus rivals at similar money: far longer battery than the Galaxy Watch 7 (40h, ~£289) and Pixel Watch 3 (24h, ~£349), and well beyond an Apple Watch SE (18h).
Versus the Watch 2 (~$299): the 2R felt slightly shorter on battery in real use and trades the steel build for plastic-ier glass — a ~$50-100 saving that doesn't fully justify itself for some.
