Apple Watch Series 3: Leave Your Phone Behind (September 2017)
The Apple Watch Series 3, launched September 22, 2017, added cellular connectivity ($399, vs $329 GPS-only) — finally enabling the “leave your iPhone at home” promise Apple had teased since the original 2015 watch.
The Cellular Revolution:
- Built-in LTE: Make calls, stream music, use apps without iPhone nearby
- Red Digital Crown: Signaled cellular model (subtle flex)
- $10/month carrier fee: AT&T/Verizon/T-Mobile added watch to plan (shared phone number)
- Battery tradeoff: 18 hours mixed use (4-6 hours cellular-only workout)
- Use case: Running/gym without phone, emergency calls, music streaming
What It Enabled:
- Phoneless runs: Runners could stream Spotify/Apple Music, take calls, track routes (freedom)
- Pool/ocean safety: Make emergency calls from water (surfing, swimming accidents)
- Minimal life: Leave phone at home for coffee shops, errands, dog walks (screen detox)
- Travel: Apple Watch + AirPods only for short trips (phone stayed in hotel)
Technical Improvements:
- S3 Dual-Core Chip: 70% faster than Series 2
- Siri spoken responses: Watch finally talked back (vs text-only previously)
- Barometric altimeter: Stair climbing, elevation tracking (skiing, hiking)
- 50m water resistance: Same as Series 2, swim tracking continues
The Antenna Innovation:
- Display as antenna: Screen itself transmitted cellular signal (space-saving wizardry)
- Launch problems: LTE connected to unknown WiFi networks (fixed in watchOS 4.0.1 days later)
- Carrier compatibility: Only worked with iPhone carrier (couldn’t mix AT&T phone + Verizon watch)
Pricing Strategy:
- $329 GPS-only (entry-level, most buyers chose this)
- $399 LTE ($70 premium + $10/month forever)
- Kept Series 1 at $249 (budget option, many preferred vs paying more)
- Hermès Edition: $1,149-$1,399 (leather bands, same tech, luxury branding)
Adoption Reality:
- GPS outsold LTE 3:1 (most didn’t value phoneless freedom at $70+$120/year)
- Gym rats loved it: Treadmill runners, cyclists who left phones in lockers
- Parents bought for kids: Kid could call parents without phone (though Series 3 overkill, GPS Family Setup better)
- Battery anxiety: Cellular drain meant nightly charging mandatory (vs 2-day GPS-only)
Cultural Impact:
- Normalized smartwatches (Series 3 was mainstream crossover moment)
- “Leave phone at home” minimalist lifestyle gained traction
- Running watch market disrupted (Garmin/Fitbit felt pressure)
- Memes about $10/month to not carry phone (luxury tax jokes)
Longevity:
- Sold until September 2022 (5 years!), longest-running Apple Watch
- watchOS 8 final update (2021, 4 years support)
- Still functional 2024 (though slow, apps crash, battery degraded)
- Refurb market: $50-100 (2024), popular first smartwatch
Why It Lasted So Long:
- Good enough: GPS+heart rate+notifications covered 90% of use cases
- Affordable: Apple kept as budget option ($199 clearance pricing common)
- watchOS support: Continued updates longer than expected
- No major feature gap: Series 4’s ECG/fall detection nice, not essential
The Cellular Reality Check:
- Most buyers never used cellular (or canceled $10/month after trial)
- Battery drain made it impractical for all-day phoneless
- Phone separation anxiety real (people felt naked without iPhone)
- GPS-only model won (cellular niche, not mainstream)
Legacy:
- Proved cellular viable (Series 4-9 continued option)
- Defined Apple Watch sweet spot ($300-400 price, fitness focus, notification convenience)
- Last Apple Watch with original design language (Series 4 redesigned)
- Most popular Apple Watch generation (units sold estimated 50M+, though Apple never disclosed)
Discontinued September 2022 (replaced by SE 2nd gen as budget option). Series 3 owners who never updated to watchOS 9 could keep using it until apps dropped support (~2023-2024).
