The watch is not under warranty anymore. 
It needs general service and the band needs. 
I no longer have the invoice or the warranty card;
 I must have lost everything during the move.
Adjusting the settings is difficult; the button 
at 10 o'clock is very unreliable, and the others are too. 
Does the strap need to be replaced, or is it enough 
to refurbish it and adjust it ?
