I had several time dealing with Swatch Group SC. First with my new under warranty Certina for the replacement of second hand. The marking paint on the second has some very tiny defect, so I email them and they ask me to send that watch back. I do talk to the AD but they said it takes around 3 weeks to let them send that watch back to SC. 3 weeks and the AD is in KL. The AD told me better to send them by myself. I'm not origin from KL that why I ask them to do that plus I'm sure the AD better know how to deal with the SC.
So, I go by myself. Register at the counter, around 10 minutes they call me and I show the watch. They inspect the watch and ask me to wait. 20 minutes later, they call me again. They replace all those my watch hand. The hour, minute and second hand. They even show me the old hand that they took from my watch.
The second time I at the SC is around last month. The CK watch that I recently bought suddenly stop. They inspect the watch and they said the battery is almost drained out. They replace the new battery and the problem solve within 15 minutes.
I do also think their priority is the walk-in customer. The service is quite fast and the waiting area is nice. Unfortunately, they only open on weekdays. I have to take a leave to take my watch there.
