@Dimitrios-Kanellopoulos I have done the update and reset my Ocean after. I have picked up an issue with Watch Faces, if anyone can confirm, but I have tried installing the Earth Day as well as Vector Classic and keep getting the issue “Oops! Something went wrong”. I have restarted my watch and phone with no luck. I will be testing more of the update in the coming days.!!
-
@dotcom Please let me know what you find, also a swimmer and testing it out later today.

@Reino-von-Wielligh
Absolutely no change: legs, one arm, nothing is better. -
@Reino-von-Wielligh
same issue on IOS with Watch Faces -
@dotcom I see now in the log that we also did not get the drill mode OR any of the recovery metrics. Must say I am very disappointed atm.

Does someone know how that Tide Widget looks like? I’d love to see and wish it for all the other models

-
Maybe it looks like this!

@Reino-von-Wielligh I got the same error
-
@Dimitrios-Kanellopoulos that is great, I have been waiting for the dive switch window customizations impatiently, also 2 tank pods on one gas is amazing. I can’t download the new watch faces , I guess the ocean lite is the one for scuba features , but it doesn’t download for me!
Everything else is amazing! -
@Horizontal_2
I would really like to see this feature on the R2 as well because I enjoy fishing, and this function would be extremely useful for me. -
@Reino-von-Wielligh Same here…

reporting the watchface issue
-
I have just updated my Ocean to 2.51.28.
Synced the watch with suunto spp - and the new watches are all downloadable and can be used on my watch.Many months ago, i reported that the race2 and outback adventure watch faces has portions of them not displaying properly or not working - they have been fixed in this update and it works for me; race2 now displays the graph or chart (before this it was blank), and the outback adventure has 2 arches on the watch face (before this it only had 1 arch at the bottom and missing the top arch).
I was also able to download on my watch the following watch faces:
Chengdu trail
Light flow
Ocean lite,
Race 2
Outback adventure
Snow slash
Vector classic
Earth dayThe tide wodget also displays information related to my location.

Looks great update:
- Performance is smooth, way faster menus.
- New options to customize dive watch looks promising, now we can leave only data we need to quickly switch between them. Not super customizable, but a great start.
- Water type is nice to have feature, guess POD additional info is also nice addon. No-fly icon was unnecesary for too long, if it is shortened - that’s a nice feature.
- Sleep report looks better, will see if alarm / night report bug is fixed.
! logbook missing. After update I only see activities for ~1 month, did not find a way to seperate other activities and diving and my older dives are missing on watch.
- not sure if daylight saving time is fixed (we are still switching winter/summer time and sync with GPS did not change it correctly, had to choose time zone manually)
- can’t find new dive watch face (not really need it, but could not find it anyway)
- sad that latest maps updates are not integrated in this update, guess we will get them in a year or so

-
@Reino-von-Wielligh Same issue with Ocean.
-
@prakalejas said in Suunto Ocean update 2.51.28:
not sure if daylight saving time is fixed
not sure if daylight saving time is fixed -> this is cached via the app FYI
-
@prakalejas Yeah also disappointed that the new maps update and swim features were not included in this update of Ocean. I remember on the slides of the updates from & April, it said coming to Ocean, but when we will get this, we can only hope Suunto starts treating the Ocean with the same urgency as the rest of the lineup.
