This surely is a quiet group.

I just sent my Ball Fireman Ionosphere chronograph for servicing at AIA Central (x-Standard Chartered). Standard price for servicing RM2030
Waiting time 1~3 months. Bought it 11 years ago for RM6k. Servicing is a third of the purchase price.

Average service price RM200 per year, so OK laaa but I wear it probably 2weeks every 3 months rotation.
