Critical AOD and other problems with Suunto Ocean 2.40.56 (2025 Q3)

[prakalejas]

Trying to prepare my new watch for diving trip and got big problems without even getting into water. (watch came with firmware ~2.38.16)

1. Full reset -> Settings -> Sleep -> Auto Do Not Disturb -> On. Shutdown watch, turn on and that’s it - AOD option no longer active, triggering Auto DND does not turn off that feature. No way to get AOD without reset. Changing screen brightness no longer works (you can toggle, but without an effect). Not sure if this is the only boobie trap to brick the watch, but this is the way to replicate 100%.
UPDATE: swipe up to widgets - > control panel - > do not disturb - > toggle “off” fixes the problem.

2. Cannot use watch without synchronization with an app on the phone. If anything goes wrong and need to do full reset - you have expensive useless wrist bracelet…

3. Maps download… Oh boy… No way to cache them on the phone and download is only activated on a charger with the speed of 0-7mbs. So that’s max 1MB/s. Decent countries take several GB… So after a full day of trying to download some maps, you can end up needing to do full reset. No way you can update your maps on the travel… + Had a watch crash, while uploading maps during charge. Happened once, but happened. Not a good trend on first day for diving watch.

Not so critical, but still important:

4. Air Integration - you can create gas, but no way to differentiate by tank capacity. If you want presets for Air 10L tank, Air 12L, Air 15L - you get 3 with a title Air. Not so easy to select the right one and ensure it is correct before the dive

5. Time formats dd.mm.yyyy and dd\mm\yyyy what happened to other formats like yyyy-mm-dd? (not critical, but lots of europeans use this format)

6. Settings after reset and sync with an app does not restore previous setup. So watch does not have some kind of backup. This might be a problem, since android app does not show what kind of previous content is missing on watch.

And these are just basic stuff, and I did not even had time to test POD and diving features…

Any hopes it gets fixes soon? Like the watch, but can’t even start to trust it due to basic stuff crashing or not working.

So after first 1h dive in a pool, I have some questions:

1. Watch on the left hand, POD from the right shoulder - half of the time I don’t get pressure readings shown. Only if I move left hand way to the right, it gets shown again. Is this some sort of closed space, indoor fluke or this is “normal” and I must use watch on the same side as pod or use some POD extension from now on? Maybe it was reading OK, but was not shown on the watch? (gas consumption graph had long gaps with 0 values, guess it is poor watch/pod connection).

Empty tank drill was nice - watch showed red alert with sound alarm.

2. Why there is no dive start and end time on the app? The only way I could find actual dive time was on the watch logbook. Bottom time and other basic data is not available neither on watch or app.

3. Stock watch strap is too small for 5mm wet suit, managed to secure it with last hole, need at least 1-2cm longer. Wonder if straps in accessories shop are longer or same max length and shorter? (watch came with single strap length, additional are sold with 3 parts).

4. Compass was meh experience, does not really have tilt compensation, so it takes a while to get accurate reading.

5. Since I will most likely will have to wear watch on the right hand, wonder if display rotation would be beneficial (watch side buttons are designed for the left hand use and feel akward wearing on the right). Some dive computers have ability to rotate display, guess this function is not available on Ocean?

But overall - decent first experience, good auto brightness, easy reading, good alerts (max depth was 4.8m, so too early to tell how it acts in open water).
