Herbert tells the sales assistant at Keiko Pty Ltd that he wants a watch suitable for scuba diving. The sales assistant declined to select a watch. Another customer in the store overhears this and tells Herbert that a particular watch "looks like one my dad bought, which I think does what you want". Herbert purchases the watch from Keiko Pty Ltd and later discovers that it is not suitable for scuba diving.

Advise Herbert whether Keiko Pty Ltd has breached any implied guarantees under the Australian Consumer Law (Competition and Consumer Act 2010 (Cth), Schedule 2).
