Suunto Ocean update 2.51.28

What are the differences in freediving after updating to 2.51.28?
I went for freediving after the update but couldn’t find any change at all.
Is the “Customization of switch window and arches for dive modes” concerning scuba or freediving? -
It seems I’m a bit late to the party!
I have to say, I’m really happy that diving got some attention in this update! I was loosing hope a bit after waiting so long for the last update, only to discover it came with zero dive features… for a dive watch.
The “Tide widget” looks really cool though I’m just getting times for “United Kingdom” which is about 45 mins out from my local beach. So it’s not that accurate. It would be great if the accuracy could be improved in a future version to “local town”. Or allow you to lookup manually.
“Customisation of switch window and arches for dive modes” - Doesn’t seem to do anything we didn’t already have unless I’m mistaken? The switch window could be cycled with the bottom button so does this just set the one it starts on? Also we could choose which arches we wanted in the app so I guess it’s good to have that on the watch but it’s nothing new. I’d still really love to have different customisable faces for dive screens. That would be awesome!
I haven’t had chance to check out the “dynamic depth graph” so I’m looking forward to that.
“Support for new dive watch face” - I can’t seem to find this? Unless it’s just the “Ocean”? Which one is it?
“Water type setting for scuba diving” - Useful. Though the default seems to be “EN13319”… what type of water is that?
Good to see some bugs getting fixed too.
Overall though great to see and actual dive update. Please keep it up! I’d love to see customisable dive screens and a better dive planner.

Ok, so it’s been a few days since update, some feedback:
BUGS:
snooze alarm, wake up, wait for sleep summary to show and then dismiss alarm - somehow it freezes even longer than before
So this one is definately not fixed.watch shows notification and vibrates of incoming call, even if you answer the call.
logbook shrunkened, lost dives and activities over ~1 month old.
battery usage increased slightly (~1-3%/day) - guess this is the price of better menu performance.
ps. OxygenOS 16 + SuuntoApp 6.9.11

Just noticed this too! Hoping it is a bug as that’s not good imo.

@Dimitrios-Kanellopoulos - Is there an updated Suunto Ocean User Guide for the May 2026 software release?
-
@GS-111 I would also like to see the updated user guide. What does e.g. dynamic depth graph mean?

Hi!
I’ve been having a problem since the firmware update.
It updated automatically on its own last week. On Saturday, I went diving, and as I started my first dive, the watch restarted on its own!
After that, a message appeared saying something like “algorithm calculation error” along with a red warning icon—it wasn’t a lockout warning.
I used it on the next dive with the same warning. In the afternoon, I restarted it from the menu, and on Sunday while diving, the red error warning popped up again. The icon looked like this:
It kept giving me readings throughout the dive (deco time, etc.). I think the Tank POD’s battery is low, because the pressure would appear and disappear, and I also noticed that the altitude wasn’t correct—on land, it told me I was at -X meters.
What could have been the problem, and what can I do? Has anything like this ever happened to you?
Thanks!

After the dive and crash, sync the watch and send the logs from the app as soon as possible.

(Different watches, but the same applies) -
