Samsung is the better watch if you are leaving the iPhone as well. Garmin will get you off a mountain. Neither of them will answer a text on the phone you already own.

If you are reading this you have already had the argument with yourself. You know what the Apple Watch does well. You have decided that something about it — the price, the nightly charging, the fact that it does not survive your job — does not work for you. So I am going to skip the part where I tell you the Apple Watch is good.
Here is the part nobody warns you about. Most Apple Watch alternatives do not work properly with an iPhone. Samsung’s Galaxy Watch Ultra is Android only. Garmin’s Instinct will not let you reply to a message on iOS at all — that is Garmin’s own wording, not mine. If you are keeping your iPhone and just want something different on your wrist, half the usual recommendations are dead before you open the box.
So I have ranked these by the reason you are leaving, because the right answer changes completely depending on what it is. Two of these beat the APEX outright for the right person, and I say so in their entries.
Start With Why You’re Leaving
- It’s the price→Njord APEX
- It’s the battery→Garmin Instinct 3 Solar
- I’m switching to Android→Samsung Galaxy Watch Ultra
- I’m keeping my iPhone→Njord APEX or Amazfit T-Rex 3 Pro
- It isn’t tough enough for my work→Njord APEX
- I need real water depth→Carbinox Edge
How I Ranked These
Not by score. By the reason someone actually leaves an Apple Watch, because those reasons do not point at the same watch. Price points one way, navigation points another, and switching phone platforms changes the answer completely.
Where I did apply a single test, it is this: does the manufacturer tell you what it tested, or does it tell you a feeling? That produces a ladder. The APEX names MIL-STD-810H, with the revision letter. Garmin names MIL-STD-810 and stops. Amazfit names nothing at all — its entire durability claim is the phrase “military grade”, which is a marketing term, not a test. That is a documentation gap, not proof the watch is weak, and I have written it that way.
The second test is whether the thing does what your day asks. Can you read it, can you answer it, will it survive being cleaned, do you have to think about the money if it takes a hit. That is why a watch with no GPS chip finishes ahead of two watches that navigate properly.
Dropped onto aggregate. The only watch on this list that is cheap, lasts weeks, works with both phones and answers a text.
Njord APEX
It is first because it is the only watch here that does four things at once: costs little, runs for weeks, works with either phone, and lets you reply to a message. Nothing else on this list does all four.
The difference that matters against every other pick is IP69K — the high-pressure, high-temperature jet rating. Apple is IP6X, which is dust only and carries no jet rating. Samsung is IP68 and says in its own footnote that it is “not suitable for high-pressure water activities”. Garmin publishes no IP rating at all. If your watch gets cleaned rather than swum in, this is the only one on the list rated for it.
The trade is honest and it is the reason three watches below beat it on water: 2 ATM is rated to 20 metres, about 65 feet. It survives a soaking, a wash bay or a pressure washer, and handles submersion if it happens, but it is not a swimming watch and I am not going to pretend otherwise.
Good
- IP69K, plus MIL-STD-810H with the revision named
- 16–18 days on a charge
- Replies to texts on iPhone and Android
- Large AMOLED, readable in sun
- Standard 22mm straps
Trade-offs
- 2 ATM — not a swimming watch
- No GPS chip — it reads your phone’s location
- No satellite SOS
- Fewer advanced health sensors
The outright winner for one specific reader: someone leaving the iPhone as well as the Apple Watch.
Samsung Galaxy Watch Ultra
If you are leaving the iPhone too, buy this one. I am not going to bury that under a ranking. It is the most capable watch on this page by a distance — premium materials, 10 ATM, published MIL-STD testing, dual-band GPS and a genuinely deep health suite.
Two honest notes, both from Samsung’s own footnotes rather than from me: the Grade 4 titanium is partially applied, and Samsung states the IP68 rating is not suitable for high-pressure water activities. Neither is a scandal. Both are the kind of detail a manufacturer publishes when it is willing to be checked.
It ranks second here only because this list is ordered by the reason you are leaving, and the single most common reason — keeping your iPhone — rules it out entirely. Samsung wins technology. The APEX wins the job.
Good
- 10 ATM
- Premium materials
- Deep health tracking
- Published 810H detail
- Bright display
Trade-offs
- Android only — will not pair usefully with an iPhone
- Battery measured in hours and days, not weeks
- IP68 excludes high-pressure water
- Expensive

Solar charging and real navigation. On an iPhone, it cannot reply to anything at all.
Garmin Instinct 3 Solar
With enough sun under Garmin’s stated conditions, the Instinct 3 Solar can avoid routine charging altogether. It also navigates properly — multi-band GPS with SatIQ, barometric altimeter, compass and outdoor routing. If you are leaving because of the battery, this is your watch.
The trade is the screen: 0.9-inch monochrome MIP on the 45 mm Solar. That is why the solar works so well, and outdoors it makes complete sense. For reading messages through a workday it is a different tool.
And the part that matters most on this page: on an iPhone there is no reply path whatsoever. Garmin’s own wording is that replies work “only using pre-set quick replies and only when paired with a compatible Android phone”. Canned responses, Android only. Garmin wins the backcountry. The APEX wins the job.
Good
- Solar — can avoid routine charging
- 10 ATM
- Real multi-band navigation
- LED flashlight
Trade-offs
- 0.9″ monochrome screen
- Polymer case
- No replies on iPhone at all; pre-set quick replies only on Android
- No published IP rating
- MIL-STD named without a revision letter
Garmin Instinct 3 Solar alternative: the full head-to-head →
The closest thing here to a Garmin at a lower price — and unlike Samsung, it pairs with either phone.
Amazfit T-Rex 3 Pro
Sapphire glass, titanium bezel and buttons, a bright AMOLED, dual-band GPS, offline maps, 10 ATM and long battery life. On paper it out-specifies almost everything on this page for the same $499 Garmin asks, and unlike Samsung it pairs with either phone.
Two things worth knowing before you buy on the spec sheet. The case body is fiber-reinforced polymer, not metal. And on toughness, Amazfit publishes no MIL-STD standard at all — the durability claim is the phrase “military grade” and nothing else.
That is the distinction this whole site is built on. The APEX names MIL-STD-810H. Garmin names MIL-STD-810 without a revision letter. Amazfit names nothing. “Military grade” is a marketing phrase, not a test. That is a documentation gap rather than evidence the watch is weak — but if you are buying toughness, you are buying a claim you cannot check.
Good
- Works with iPhone and Android
- 10 ATM
- Sapphire glass, titanium bezel
- Offline maps, dual-band GPS
- Long battery
Trade-offs
- Polymer case body
- Large case
- Zepp OS
- No published MIL-STD standard — “military grade” only
The one combination nothing else here has: 5 ATM and IP69K together — submersion and jet spray.
Carbinox Edge
Stainless steel, Gorilla Glass, AMOLED, standalone dual-band GNSS — and the rare pairing of 5 ATM and IP69K together. That combination covers submersion and high-pressure jet spray at once, and nothing else on this list does both. If you swim in your watch, this is the entry to read twice.
The catch is messaging. The researched Carbinox material says SMS and social notifications can be read, but direct replies were not generally available beyond some limited Android voice-to-text wording. The same material gave inconsistent battery figures and did not publish a MIL-STD revision.
We have taken those claims apart in detail in our Carbinox Edge alternative head-to-head, rather than repeat the work here.
Good
- 5 ATM and IP69K
- Stainless steel and Gorilla Glass
- Standalone dual-band GNSS
- AMOLED display
Trade-offs
- Limited or no direct text replies, on the sourced wording
- Closed system
- No published MIL-STD revision
- Battery wording inconsistent between sources
What The APEX Is Not
It has no GPS chip. It reads your phone’s location. If you navigate off-trail for a living, that is disqualifying, and the Garmin’s multi-band GNSS is in a category the APEX does not compete in.
It is 2 ATM — about 20 metres, 65 feet. Rain, mud, washing, a short dunk. Not swimming and not diving. The Samsung, the Garmin and the Amazfit are all 10 ATM, and the Carbinox pairs 5 ATM with IP69K.
There is no ECG and no blood-pressure sensing. If you are leaving the Apple Watch because you want more health measurement rather than less, the Samsung is the watch on this page for you and the APEX is not.
How To Actually Choose
Work backwards from the reason you are leaving. Switching to Android? Samsung, and it is not close. Leaving over the battery, and you navigate? Garmin. Going underwater? Carbinox, or the Samsung. Keeping your iPhone and you want a watch that survives your work? That is the APEX, and it is why it is first.
Two of these out-specify it. Samsung is the more capable watch by a distance. Amazfit has sapphire, titanium and offline maps for $499. Neither of those is in dispute, and neither is diminished by ranking below — they rank below because most people leaving an Apple Watch are keeping their iPhone, and that single fact removes one of them from consideration entirely and strips the other of its reply function.
A specification can win a category. The product still has to win the job.

Mark ran commercial crews for years before he started writing about the gear he used to buy for them. He tests on the specification sheet first — what the manufacturer will put in writing, and what it quietly will not — and on the job second. He has no time for the phrase “military grade”.
