stopwatch on nav map not working

[GoldenRivet]

The wood clock?

it is tied to the stopwatch in the periscope views and will only tick away if you are actively timing a torpedo's time to impact.

Ie, you take your shot, the red hand appears at the impact time, the second hand starts ticking... pull down the wooden stopwatch in the map view and it will also be running.

but you cant run that clock independently of the periscope clocks
