Ships clock help Please!

[Jolly Roger]

I wonder if anyone has any knowledge of how to adjust a battery operated ship’s clock bell striking.
I have an old Hermle hammer striking movement in a beautiful 6” brass case, which strikes all four hours, (even number) bells, but it also strikes the half hours with the same numbers. So we can’t tell from the sound whether it’s on the hour or half hour.
I’ve examined it closely and can’t find anything broken or dislodged.
It keeps perfect time, but if I can’t solve the chiming I will have to disconnect the striker.
Any help would be appreciated—it’s driving us crazy.

Hermle Ship Bell Clock Operatiing Instructions and Bell Strike Schedule

The ship's bell strikes every 30 minutes and increments by one strike every half hour over a 4 hour period until it reaches 8 strikes. The bell strike begins with a single strike at half past midnight and counting up to 8 bell strikes at 4:00 a.m. marking the end of the 4 hour watch period. At this point the bell strike pattern begins again at a single strike at 4:30
and counts up to 8 strikes to 8:00. The cycle is continuous over the 24 hour period.

Bell Strike Schedule:

· 12:00, 4:00, 8:00 =8 bell strikes
· 12:30, 4:30, 8:30 =1 bell strike
· 1:00, 5:00, 9:00 =2 bell strikes
· 1:30, 5:30, 9:30 =3 bell strikes
· .... continues counting up to 8 bell strikes

Good try Gord, but Rosie left Hermle about eight years ago, and they don’t have anyone there who knows anything about their older movements.
Perhaps I should have mentioned I’ve explored everywhere on the web, and phoned a number of clock suppliers who use Hermle, but without success.
I’m just hoping someone on the forum has met this problem before, and solved it without the use of a large house brick.
