COROS VERTIX 2S
Get COROS VERTIX 2S if battery life comes first: up to 118 hours of GPS and 36 days of daily wear, in a titanium and sapphire case, for $699.
In short
Get COROS VERTIX 2S if battery life comes first: up to 118 hours of GPS and 36 days of daily wear, in a titanium and sapphire case, for $699. With every satellite system on it's still rated for 73 hours. The trade-off is size: it's 50.3mm across, 16mm thick and 87 grams on silicone, with a Memory LCD rather than AMOLED. If that's too much watch, the 46mm APEX 2 Pro costs $449.

Who it is for
- Ultrarunners and multi-day racers. Even Max Dual Frequency, its most demanding GPS mode, is rated for 43 hours.
- Winter athletes and cold-weather hikers. COROS rates it to work from −22°F to 122°F (−30°C to 50°C).
- Buyers who want premium materials: a Grade 5 titanium bezel and cover with PVD coating, sapphire glass, and a digital dial COROS made bigger and tougher.
- Navigators. Landscape and topo maps download into 32GB of storage, and a dedicated button turns on the backlight.
Who should skip it
- Anyone with a slim wrist or a taste for light watches. It weighs 70 grams even on the nylon band, and it takes 26mm straps.
- Anyone who wants a color AMOLED screen. The 1.4-inch Memory LCD shows 64 colors; for AMOLED, look at PACE Pro.
- Divers. Despite the 10 ATM rating, COROS says VERTIX 2S is for surface water activities, not diving.
- Anyone who doesn't need weeks between charges. APEX 2 Pro is smaller, at 46mm on 22mm straps, and costs $449.
What sets it apart
- GPS ratings of 118 hours in Standard Full GPS, 73 in High All-Systems and 43 in Max Dual Frequency.
- 36 days of daily use with sleep tracking between charges, and a full charge in under 2 hours.
- A Grade 5 titanium bezel and cover under sapphire glass, rated 10 ATM.
- 32GB for downloadable landscape and topo maps and music, plus an ECG sensor.
Caveats
- Music cuts deep into the battery: with offline music playing, Standard Full GPS falls from 118 hours to 32, and Max Dual Frequency from 43 to 22.
- At $699 you still don't get tap-to-pay or cellular; COROS lists neither.

COROS VERTIX 2S extras
Specs only this model has.

|---|---|---|
| Sizes | 50.3mm only. APEX 2 Pro is the 46mm alternative; PACE Pro is the AMOLED one | COROS VERTIX 2S specs (US) |
| Maps | Downloadable global landscape and topo maps; checkpoints; back-to-start; off-route alerts; touchscreen map control | COROS VERTIX 2S specs (US) |
| Offline music | Plays offline music to supported Bluetooth headphones; GPS hours drop sharply with music on | COROS VERTIX 2S specs (US) |

Battery measured in weeks
This is the reason to buy a VERTIX, and COROS rates it like this:
| Mode | VERTIX 2S | With offline music |
|---|---|---|
| Standard Full GPS (GPS and QZSS) | 118 hours | 32 hours |
| High All-Systems | 73 hours | 27 hours |
| Max Dual Frequency | 43 hours | 22 hours |
| Daily use and sleep tracking | 36 days | — |
118 hours works out to almost five days of continuous GPS. In everyday use, 36 days with sleep tracking means charging about once a month, and a full charge takes under 2 hours.
Titanium, sapphire and a big case
The bezel and cover are Grade 5 titanium with a PVD coating, under sapphire glass. The case measures 50.3 × 50.3 × 16mm and weighs 87 grams on the silicone band, 70 on nylon.
Its 1.4-inch, 280 × 280 Memory LCD shows 64 colors and stays on. COROS says it made the digital dial larger and tougher, and there’s a back button plus a dedicated backlight button.
Cold weather and navigation
COROS rates VERTIX 2S to work in temperatures from −22°F to 122°F (−30°C to 50°C).
For navigation it downloads global landscape and topo maps, with checkpoints, back-to-start, off-route alerts and touch control, backed by a barometric altimeter and 3D compass. The 32GB of storage holds maps and music together. Training runs through COROS’s EvoLab, the same load, recovery, VO2 max and race-prediction tools as the PACE watches.
VERTIX 2S or APEX 2 Pro?
| Spec | VERTIX 2S | APEX 2 Pro |
|---|---|---|
| Case | 50.3mm | 46mm |
| Straps | 26mm | 22mm |
| Water resistance | 10 ATM | 5 ATM |
| Daily use | 36 days | 21 days |
| Standard Full GPS | 118 hours | 66 hours |
| US price | $699 | $449 |
APEX 2 Pro is the smaller, cheaper option. Pay for VERTIX 2S if you’ll use the extra battery or the 10 ATM rating. If what you really want is a color AMOLED screen, look at PACE Pro instead, a polymer watch with far shorter battery ratings.

Frequently asked questions
Is VERTIX 2S a dive computer?
No. It's rated 10 ATM, but COROS says it's for surface water activities, not diving, and doesn't list EN13319 dive certification for it.
Will my 22mm COROS bands fit?
No. VERTIX 2S takes 26mm bands: nylon in a 155–225mm size or silicone in 130–240mm.
Is the screen always on?
Yes. It's an always-on Memory LCD, and COROS's 36-day rating comes with no separate always-on figure, unlike the AMOLED PACE models.
Does VERTIX 2S have ECG?
Yes. COROS lists an electrocardiogram sensor alongside optical heart rate and a pulse oximeter. Its readings aren't a diagnosis.
