Display
Case sizes42 mm or 47 mm47 mm
PanelOLEDOLED
Always-on displayYesYes
Display detail42 mm version has a 1.2 inch AMOLED touchscreen with 390 x 390 pixels; 47 mm has a 1.4 inch screen with 454 x 454 pixels. Optional always-on mode and ambient-light sensor. Three physical buttons. UK table pairs the 42 mm screen's 1.2 inch figure with 32.02 mm, an inconsistent conversion; neither value is silently recalculated here. Launch German datasheet also incorrectly repeats 390 x 390 for the 47 mm display; exact current model tables establish 454 x 454.33 mm (1.3 inch) AMOLED touchscreen, 416 x 416 pixels, five physical buttons; always-on option and red-shift mode.
Screen protectionCurrent UK and US model tables specify Corning Gorilla Glass 3. German launch article calls it sapphire, conflicting with its own attached Gorilla Glass datasheet; no sapphire configuration is established.Corning Gorilla Glass; no Sapphire configuration in the exact current range.

SensorsGPS, GLONASS and Galileo; 47 mm additionally has multi-band positioning and SatIQ. The exact German datasheet distinguishes 42 mm multi-GNSS from 47 mm multifrequency; current UK/US tables likewise list multi-band and SatIQ only on 47 mm. Both have Garmin Elevate wrist heart rate, Pulse Ox, barometric altimeter, compass, gyroscope, accelerometer and ambient-light sensor. Maker does not number the optical sensor generation.GPS, GLONASS, Galileo, QZSS and BeiDou; Garmin Elevate wrist heart rate, Pulse Ox, barometric altimeter, compass, gyroscope, accelerometer, thermometer and ambient-light sensor. Single-frequency GNSS, with no multi-band/SatIQ (confirmed by exact Wareable and T3 tests); maker does not number the heart-rate sensor generation in its current table.
Health featuresContinuous heart rate, resting rate and high/low alerts, respiration, Body Battery, stress, advanced sleep, sleep coach, nap detection, HRV status, Health Snapshot, fitness age and jet-lag adviser. Pulse Ox spot checks and optional sleep monitoring. Hydration and menstrual-cycle/pregnancy tracking use Garmin Connect and an optional Connect IQ widget; these are wellness features, not medical diagnosis.Continuous heart rate and high/low alerts, respiration, Body Battery, stress, advanced sleep tracking/coach/score/alignment, breathing variations, nap detection, HRV status, Health Snapshot/Status, jet lag adviser and lifestyle logging. Current table lists smart wake alarm. Hydration and menstrual-cycle/pregnancy features use Garmin Connect and optional Connect IQ widget. Pulse Ox is not available in every country. No ECG or skin-temperature feature is listed for this exact hardware; the ambient thermometer does not establish skin-temperature tracking.
Fitness featuresOver 43,000 preloaded golf courses, full CourseView vector maps, pan/zoom and touch targeting, green view with manual pin position, hazards, layups, front/middle/back distances and PinPointer. Enhanced PlaysLike distances account for slope, weather and air pressure; wind information requires a phone connected to Garmin Golf. Virtual Caddie offers club recommendations and shot-dispersion charts after five rounds with uploaded scorecards and either optional CT10 sensors or Club Prompt enabled; sensors are not mandatory. AutoShot detects fairway shots; optional CT10 sensors add putt/chip detection. Optional CT1 tags and Z30 laser range finder are supported.

Download free regional TopoActive maps over Wi-Fi for offline navigation; dynamic round-trip routing, turn-by-turn courses, NextFork, TracBack and back-to-start. Maker table calls road/trail maps “Yes (downloadable)”; do not treat them as preinstalled. Golf courses and ski-resort maps are listed as preloaded; premium map contents require optional Outdoor Maps+ subscription.
Safety featuresIncident detection during supported activities and assistance require a paired compatible phone and available network; not standalone emergency communication.Incident detection during selected activities, assistance, LiveTrack and live event sharing require a compatible paired phone/connectivity. Screen flashlight lights the display; no separate LED torch. Current web safety table marks hands-free voice control, but Garmin’s Japanese launch explicitly excludes fēnix E from speaker/microphone/voice commands; that ambiguous table entry does not establish those hardware features. No dive-rated inductive buttons, depth sensor, LTE or satellite messaging.
