Apple Watch Ultra 2 at $405 vs Ultra 3 at $640: Which to Buy Before Ultra 4 Launches
The Apple Watch Ultra 2 just hit $405 on Amazon — its all-time lowest price and a stunning 49% discount from the original $799. With the Ultra 4 expected in September and the Ultra 3 sitting at $640, buyers face a three-way decision. Here's exactly how each generation compares and which one deserves your money.
Ultra 2
$405 on Amazon (was $799). S9 chip, 2,000-nit display. Best value.
Ultra 3
$640 on Amazon (was $799). S11 chip, 3,000-nit display. Current flagship.
Ultra 4
~$799 estimated, September 2026. Thinner, new sensors, better battery.
How Do the Three Ultra Generations Compare?
All three Apple Watch Ultra models share the same DNA: a 49mm titanium case with sapphire crystal, cellular connectivity included, dual-frequency GPS, 100m water resistance, EN 13319 dive certification, an Action Button, and a siren. The differences are under the hood:
- Processor: Ultra 2 has the S9 chip, Ultra 3 the S11, Ultra 4 is expected to use the S12 — each generation roughly 20–30% faster with better power efficiency
- Display: Ultra 2 peaks at 2,000 nits, Ultra 3 at 3,000 nits. Ultra 4 is expected to maintain or slightly exceed 3,000 nits
- Battery: All claim 36 hours normal use and 72 hours low-power mode. Ultra 4 is rumored to add a 25% improvement — potentially 45 hours normal use
- Health sensors: Ultra 3 added improved sensors over Ultra 2. Ultra 4 may introduce blood pressure trend tracking and new band-based sensors
- Design: Ultra 2 and Ultra 3 are dimensionally identical. Ultra 4 is rumored to be 10–15% thinner
Who Should Buy the Ultra 2 at $405?
The Ultra 2 at $405 is the right choice if you:
- Want maximum value: You're getting a titanium cellular smartwatch with dive certification for less than the aluminum Apple Watch Series 11 costs at full retail ($429)
- Don't need the latest chip: The S9 is still fast enough for every watchOS app and complication — you won't notice the difference in daily use
- Prioritize proven reliability: The Ultra 2 has been in production for three years with a well-understood track record
- Plan to upgrade in 2–3 years anyway: At $405, the Ultra 2 can be a bridge device until Apple's rumored redesigned Watch lineup arrives in 2027+
Who Should Buy the Ultra 3 at $640?
The Ultra 3 at $640 makes sense if you:
- Want the brighter display: The jump from 2,000 to 3,000 nits is noticeable outdoors — particularly for runners, cyclists, and hikers reading the screen in direct sunlight
- Value on-device Siri: The S11 chip handles Siri requests without an internet connection — useful in remote areas where the Ultra excels
- Want longer software support: Being one generation newer means an extra year of watchOS updates compared to Ultra 2
Note: the Ultra 3 will likely drop to $500–$550 once the Ultra 4 launches in September, so waiting a few weeks could save you $100+.
Who Should Wait for the Ultra 4 in September?
Wait for the Ultra 4 if you:
- Want the thinnest Ultra: A 10–15% thickness reduction would make the Ultra significantly more comfortable for everyday wear and for sleeping
- Care about blood pressure: If blood pressure trend tracking ships as rumored, it would be a genuine health feature that older models can't replicate via software
- Always buy the latest: At $799, you're paying $394 more than the Ultra 2 clearance price for the newest chip, best battery, and longest software support runway
What About Non-Apple Alternatives?
If you're not locked into the Apple ecosystem, the Ultra 2 at $405 faces stiff competition:
- Samsung Galaxy Watch Ultra 2 ($639): 72-hour battery life, Snapdragon Wear Elite, three new health sensors. Works with Android phones only
- Garmin Venu 4 ($540): AMOLED display, Garmin's deep fitness ecosystem, 11-day battery life. Cross-platform
- Garmin Fenix 9 ($999, August 25): The outdoor king with tri-band GPS and MIP Solar option. For serious athletes
- Google Pixel Watch 5 ($399, August 20): Round design, Gemini AI, cloud GPS. Pixel ecosystem
Our Verdict: Which Ultra Should You Buy?
Best value: The Apple Watch Ultra 2 at $405. At this price, it's the most compelling premium smartwatch deal on the market. You're getting a titanium cellular watch with dive certification for less than most standard smartwatches cost at retail.
Best current model: Wait 3–4 weeks and buy the Ultra 3 after the Ultra 4 launch drops its price to ~$500–$550. That gets you the current-gen chip and brighter display at a significant discount.
Best for the long haul: Wait for the Ultra 4 in September if you plan to keep your watch for 3+ years and want the newest sensors and longest software support runway.
