Suunto Vertical 2 General Discussion
-
@Manuel-Extreme Thank you for this. We often come here for tech help or to vent, but rarely do people come back to say that things are working great now and that they are super happy. To me this leaves a feeling out there in the world that Suunto is not a good brand.

@AYHAN-YILDIZ sorry, cannot understand the screens. But on the last one it seems that the watch is taking a measurement as it should, no?
-
@Stavrogin Forums are mostly a bubble of people seeking help. Nobody goes to a forum if everything is great. That’s why you get the impression you have. The many thousands who don’t have any problems, i.e., the majority of users, don’t go to forums.
-
@Manuel-Extreme What software version are you currently using, and are you able to perform manual SpO₂ measurements via the widget on firmware version 2.48.16?
Because Suunto representatives have stated that this is no longer possible, claiming it was removed for battery optimization and to provide more reliable dat -
@AYHAN-YILDIZ I just tried this and it works just fine via widget. Latest firmware.
-
@AYHAN-YILDIZ Yes, it works fine. Same firmware.
-
@Stavrogin forums are often used to look for solutions to problems, which leads to more negative posts than positive ones. For me, Suunto has always been an excellent device with an outstanding value for money.
When issues are resolved, it is good to give the feedback it deserves.

@nicovoim Official clarification from Suunto Support (quote):
“Starting from firmware 2.48.16, manual SpO₂ measurement via the widget is no longer supported on Vertical 2.
The removal is firmware-based, not server-side.
Any manual SpO₂ measurement still working after 2.48.16 is not intended or supported behavior and may be related to incomplete updates or edge cases.”My watch was taken out of the box and updated immediately to 2.48.16.
Manual SpO₂ worked only a few times and then stopped completely, while sleep SpO₂ works normally, confirming the sensor is fine.So if manual SpO₂ still “works” on some devices, according to Suunto this is not expected behavior and will likely disappear after a clean update, reset, or re-sync.

@AYHAN-YILDIZ i dont believe this… Cause what you write is not in the Vertical 2 description. And also not in the Firmware Update Infos. No official Statement there chanchings of the o2 measurement. It works like expected at the latest Firmware.

@GiPFELKiND Same here

@AYHAN-YILDIZ this looks to be a response generated by large language model AI. LLMs are prone to hallucinate, which means generating perfectly formulated responses that look credible but are wrong.

@halajos Hello,
no — this is not an AI-generated assumption. This information comes directly from Suunto support and has also been officially confirmed via email.Suunto has now initiated a technical investigation on the server (back-end) side to understand why, with firmware 2.48.16, a manual SpO₂ trigger that is not supposed to work is still functioning on some devices or accounts.
My own experience supports this:
I upgraded the watch directly to firmware 2.48.16 when I first received it
The first 3–4 manual SpO₂ measurements worked perfectly
Then the manual measurement suddenly stopped
Since that moment, it has never been possible to start a manual SpO₂ measurement again
This behavior strongly suggests that the issue is not a simple firmware bug, but rather related to a server-side configuration, trigger, or feature-flag change applied after synchronization.
Therefore, the statement that “manual SpO₂ was removed in 2.48.16” does not appear to have been applied uniformly or simultaneously to all users.
In short:
this is not speculation and not AI-generated — it is a confirmed issue currently under technical investigation by Suunto. -
@GiPFELKiND hi;For clarity:
Manual SpO₂ was not working on my device. I performed a factory reset, and now manual SpO₂ works correctly via the widget.It was stated that this feature was removed in firmware 2.48.16.
If that is the case, why does it become functional again after a factory reset?I would appreciate a clear and official explanation.
-
Funny thing, I tried the manual Spo02 measurement on my 9 peak pro (on 2.48.16) and the thing promptly, immediately, crashed and turned itself off.
How the f**** is that considered even remotely acceptable ?
I hate, absolutely hate how since the last few years Suunto firmware stability just became a gigantic joke it’s so awful, it’s like they don’t even try it !
-
@Elipsus Vertical2 is working perfekt. Also after 10 times of o2 measurements.
-
@AYHAN-YILDIZ @Elipsus I can confirm that the SpO2 widget is working on field test firmware. I have no idea where the information stating this was disabled was generated from.
