I live in Australia and as a collector of wrist and antique pocket watches over the years. I have purchased wrist watches from many dealers through the internet, in Japan, Hong Kong and Singapore. On the whole, they are reliable enough, but I have found one in particular that is above the rest for communication, reliability, shipping and above all the item being delivered in showroom condition every time. The company I refer to is Creation Watches which has a base here in Sydney and in Singapore. Their range of manufactured time pieces are extensive and price competitive and Creation always include free international shipping with your order.
I can thoroughly recommend Creation Watches to anyone wanting to purchase a wrist watch which is either unavailable or too high in price in their own country.
