We do not test any watches for their accuracy and as such timekeeping cannot be guaranteed.

We advise that if you are bidding on a watch, that you or your agents are completely satisfied with the condition of the lot. We recommend that all watches are serviced and polished after the sale as they are handled throughout the viewing period. Please note that although Bonhams endeavour to include reference to any replacement parts within our Condition Reports we cannot confirm that each individual element of the watch is original or that, if replaced, the replacement has been made using original manufacturer's parts.

Please note that due to the UK leaving the European Union there will be further import charges applicable if you are based in the EU. Please do familiarise yourself with local duties.
