You should have more issues in cold weather than in hot one … but for sure sweat doesn’t help. Give a try to the wristband trick

@Mff73 yes not deleted just kept as summaries only (same with FW update)

@Matthew-Robertson Yes. SA: Uses your mobile configuration (in Android English language is assumed as week start on Sunday) Watch: You can configure on Seetings\General\Time&Date\Start Week on So you have 2 options: Modify your watch to Sunday or change your phone language to use a ‘culture’ with start week on Monday (like Spanish) BR

@Vasco363 have you looked into Movescount sailing apps? I also use my suunto for sailing. I originally had a Traverse aplha and it was lacking the sailing metrics I needed for Sailing until I started using the apps offered in Movescount. Was able to add everything from nautical speed/distance, long/lat, race timer to ENE/ETA. If you are using SA I would consider using Movescount (web) and SA to access full functions of your Ambit. I have upgraded in the last year to Suunto 9 baro, unable to use apps anymore but the S9 (almost) has what I need at the moment when it comes to metrics.
