Well, share my experience with CW.
I bought 2 watches at their London Showroom. I went to UK 2 years ago. At their website I make a booking to visit. Somehow when I arrived they told me they did not receive my booking. However without booking they still welcome me and told me to give them 30 mins to prepare.
The showroom is located at a small street... well it's a dead end street, but with the help of GPS, I still be able to find them.
Inside the showroom, the decoration is like a living room and a few sofa. Inside the room, there's a small bench table, is for them to adjust the staps size and double check the watches before delivered to your hand. Also they took down all your information. They have almost all the models except few. They let you to test kao kao on your wrist.
Finally I bought 2 watches from them. Since I left they still send me their magazine and I just receive 2 vouchers from them. 100 pounds n 50 pounds. The conditions is for 100 pounds discount voucher, the watch purchase price must be over 500 pounds and for 50 pounds should exceed 300 pounds watches. Expiry date is till 31st Oct. 2016.
As far as I know they do send the watches to Malaysia with free shipping cost. This is what they told me b4 I left.
Anymore you want to know? I'm happy to share my experience.
