suunto 9 incorrect time sync from gps

[jor di]

recently whenever I start a workout, the date and time on my suunto 9 get updated to completely incorrect values

date = 2 days ago
time = 15 hours ago approx

how can I stop this from happening?

I copy paste my replies so we can use this thread

• Have you tried a soft reset ?
• Have you set dual time ? https://www.suunto.com/en-gb/Support/Product-support/suunto_spartan_sport_wrist_hr_baro/suunto_spartan_sport_wrist_hr_baro/features/time-and-date/

It looks like the time is being updated during the activity
Which kind of sport mode do you use ?

[jor di]

• I do not know how to do a soft reset. can you explain?
• yes I have set dual time. should I disable? if so, can you tell me how to do that?

I have had this happen to me when doing “running” and when doing “weight training” (the latter more surprisingly so, since it should not really require GPS…)

@jor-di
To soft reset the watch keep the upper right button pressed for 12sec

Is the “second” time the one shown after the activity ?

[jor di]

re the question “is the “second” time the one shown after the activity ?”
no. the date/time shown seems entirely random. the date gets set back by 2 days and the time by a random number of hours and minutes. the time it resets to does not correspond to any known time zone (I think except for Iran and some places in India, the difference between time zones is whole hours, so that at least the minutes should match…)

sry … typo, I meant right

@sartoric gotcha. I removed my answer to that in my reply because I thought I had misread your reply…

Try to record a dummy activity to see what will happen after reset

[jor di]

@sartoric tried that. so far so good. will try a few more times to see if it keeps acting “normally” or whether the problem recurs
