Where is the stopwatch?

[Tripolith]

I am running the LSH mod 2015 with the GUI widescreen - nothing else.

My question is - what do I need to do to get the stopwatch also visible on the navmap which would be very practical to find targets just by the hydrophone contacts. I found it in the periscope view but don't know what to do get it on the map. The forum posts are somewhat confusing as they suggest different things:

-- hit "c" which actually crash dives or
-- hit "x" which activates the Schnorchel or
-- there is no stopwatch in the navmap as the SH3.exe doesn't allow for it

Any help? Any additional mod I would need?

Thank you so much!
