Garmin’s published figures describe the model when new; they do not predict the battery life or condition of an individual used watch. Garmin marks the model discontinued on its Singapore product page, so check the specific watch and accessories before buying.
Garmin fēnix 5S at a glance
| Specification | Garmin’s published figure |
|---|---|
| Case dimensions | 42 × 42 × 15 mm |
| Display | 1.1-inch color display, 218 × 218 pixels |
| Weight | 67 g with silicone band |
| Band | 20 mm QuickFit |
| Water rating | 10 ATM; Garmin describes this as pressure equivalent to a depth of 100 m |
| Battery claims | Up to 9 days smartwatch mode; up to 14 hours GPS with wrist heart rate; up to 40 hours UltraTrac in Garmin’s manual |
These are manufacturer specifications, not independent test results. Garmin’s battery information says actual life depends on enabled features, including activity tracking, wrist-based heart rate, notifications, GPS, and connected sensors. A separate Garmin comparison lists UltraTrac at up to 35 hours without wrist heart rate; the figures use different stated conditions, so neither should be treated as a guarantee for an older watch.
Size and everyday fit
The 5S is the smaller option compared with the standard fēnix 5, which Garmin lists with a 47 mm case and 22 mm band. Its 42 mm case gives buyers seeking a more compact fēnix a clear size distinction, though dimensions alone cannot establish how it will fit every wrist. Garmin lists the 5S at 67 g with its silicone band.
For replacement bands, look for a 20 mm QuickFit-compatible band, not just any band described as 20 mm wide. Check the specific listing for compatibility. If buying a replacement charging/data cable, confirm fēnix 5/5S compatibility on the listing as well.

Display, battery, and water rating
Garmin lists a 1.1-inch, 218 × 218-pixel color display. The official battery figures are stated as “up to” estimates: up to 9 days in smartwatch mode and up to 14 hours in GPS mode with wrist heart rate. For UltraTrac, Garmin’s manual says up to 40 hours, while a Garmin comparison gives up to 35 hours without wrist heart rate. Settings and enabled features affect runtime, and a used unit’s battery condition is not established by these original estimates.
Garmin rates the watch 10 ATM and describes that rating as pressure equivalent to a depth of 100 m. This is the manufacturer’s rating, not a recommendation for a particular diving activity. The watch has a rechargeable built-in lithium-ion battery. Garmin advises cleaning and drying the charging contacts before charging or connecting the watch to a computer.

What to know before buying used
Garmin’s Singapore product page labels the fēnix 5S discontinued. That regional page does not establish availability everywhere, current service options, or the condition of any used example. The research available for this review also does not verify the watch’s current firmware status, app-support lifecycle, or current prices.
- Ask the seller to demonstrate that the watch charges, syncs, and records an activity.
- Check battery behavior during use; Garmin’s original estimates cannot establish the remaining capacity of an individual older unit.
- Inspect the display, buttons, case, band connection, and charging contacts for damage or wear.
- Confirm that a replacement band is both 20 mm and QuickFit-compatible, and verify charging-cable compatibility at the listing level.
Verdict
The fēnix 5S is a compact fēnix 5-family watch with clearly documented dimensions, a 20 mm QuickFit band, and manufacturer battery estimates that vary by mode and stated conditions. It may suit someone considering an older, used watch who values its smaller case, but the evidence here does not establish current software support, market value, or the condition of any particular unit. Assess the actual watch rather than relying on its original specifications alone.
