Do exist a chronometer for Nokia 7710 symbian s90?

Hi
I have this splendid cellular phone for a long time but I 'm not able to find a chronometer software.
Could you help me? Do you know it?
I already proved the following software but without success:

- Alarm Clock : stay on "course operation" and it need to turn off.
- ChronoTimer : stop and start "course operation" then it don't go ahead.
- Cronometro : stop on course copy.
- Handy Clock : install but don't start.
- mCountdown : install but dont'start.
- MobipaqSwatch : install but dont'start.
- mStopwatch : install but dont'start.
- PocketCounter : install but dont'start.
- Spruce Stopwatch : signal "archive download" 6kb, then ask "Internet download" and make a choice between mms (stop), wap (start but signal "invalid file") and gprs (finish the download but signal "invalid file").
- Stopwatch : signal "course copy" and stop.
- Timetool : install but don't start.

Then I buyed mCountDown/Timer 1.02 on www.handango.com but don't work!
Now I looking for repayment of $17 charges.
It's impossible install a functional chronometer software on this cellular phone??
Thank to all
Marco
