Not bad advice and It is a risk, yes, but so is wearing your Rolex sitting in an office on your own as we have seen over the last few days. Theft could cause insurance problems but I always find a decent hiding place for my valuables when away. I don't wear an expensive watch to work very often so when I'm away it's the only chance I get to wear one consistently i.e 14 nights on the trot. I do go back to the same place most years so my familiarity with it gives me a sense of security, I realise that is not always the norm.
So it's the G shock for out on the water and my PO for the evenings.
