Repeater Classic:
42mm Width, 13.5mm High 
Five Minute Repeater 
Chimes the time on demand to the nearest 5 minutes lapsed
"Ding" for Hours
"Ding Dong" for 5 mins 
For example; 11:59 would sound as 11 "Dings" and 11 "Ding Dongs" because the time is between 11:55 and 12:00. Midday would sound as 12 "Dings"
This watch will definitly put a smile on your face!
