Garmin
Garmin Enduro 3
The battery king for ultra-distance: 120 h in GPS mode (60 h multi-band) and 36 days in smartwatch mode, extendable with solar charging. MIP display, topo maps, LED flashlight and just 63 g. Built for 100-milers, multi-day crossings and backyard ultras without worrying about battery.
Coros
Coros Apex 2 Pro
Mountain watch with outstanding battery life: 66 h in full GPS, 26 h in dual-frequency and up to 21 days in daily use, at just 53 g. Free offline maps, multi-band GPS, MP3 music and touchscreen. The light, long-lasting alternative to Garmin for ultras and crossings.
Garmin
Garmin Instinct 3 Solar 50 mm
Ultra-rugged GPS watch with solar charging: up to 40 days in smartwatch mode (unlimited with sun), 60 h GPS and 34 h multi-band. Military-standard case, LED flashlight and dual-frequency GPS. For those who prioritise toughness and battery over onboard maps on their mountain outings.
Suunto
Suunto Vertical 2
Adventure watch with a 1.5" 2,000-nit AMOLED display, a bezel-integrated LED flashlight (white and red, with SOS mode) and free offline topo maps. Up to 65 h of dual-band GPS and 20 days of daily use. Built for long ultras, mountain traverses and night sections.
When the challenge lasts several days —a stage crossing, a mountain expedition or a self-supported effort with no power outlets— the watch moves into another league. Here we’re not talking about 30 hours of GPS, but whole days of tracking, solar charging, onboard offline maps and a case that survives everything you throw at it. This comparison picks the watches built so you never worry about the charger.

What sets an expedition watch apart
Extreme battery (and solar)
The Garmin Enduro 3 is the absolute reference: 120 h in GPS and 36 days as a watch, extendable with its solar charging on sunny days. The Suunto Vertical 2 (65 h in dual-band) and the Instinct 3 Solar also play in this league. Solar charging isn’t a marketing trick: on summer crossings it gives you real extra hours.
Onboard offline maps
When self-supported, getting lost isn’t an option. Free offline topo maps (Enduro 3, Suunto Vertical 2, Coros Apex 2 Pro, Fenix 8, Polar Grit, Amazfit T-Rex 3) place you relative to the terrain even with no signal and no track. The only one in the table without maps is the Instinct 3, which makes up for it with ruggedness and solar.
Ruggedness and flashlight
An expedition punishes gear. Military standard (Instinct 3, Amazfit T-Rex 3, Fenix 8) and the built-in LED flashlight (Enduro 3, Fenix 8, Instinct 3) make the difference at bivouacs and nighttime camp setups.
Our recommendations by profile
- Best Overall — Garmin Enduro 3. Unbeatable: the longest battery on the market, maps, flashlight and solar, at just 63 g. If you take multi-day seriously, it’s the definitive investment.
- Best Value — Coros Apex 2 Pro. 66 h, offline maps and multi-band for far less. The sensible choice for 2-4 day crossings.
- Best rugged & solar — Garmin Instinct 3 Solar. Near-unlimited battery in daily use and an indestructible case for the harshest environments.
- Best for navigation — Suunto Vertical 2. 1.5” AMOLED, full-colour maps, an LED flashlight and 65 h in dual-band: the mountain navigator par excellence.
If you’re going for a big crossing and the budget allows, the Enduro 3 has no rival. If you want balance, the Apex 2 Pro gives you 80% for much less.
