The Watch Market is very bouyant with the most prominent names commanding six figure sums (or in the case of a Rolex owned by Paul Newman $17.8 Million). Names like Omega, Cartier, IWC, Jaeger-LeCoultre and Patek Philippe are all very sought after.
More obscure makes can also make considerable sums with our own World Record coming from a Heuer SKIPPER "Skipperera" selling for over £62,000 to a New York banker and delivered by taxi to The Mayfair Hotel where he was staying (it had been bought 20 years before at auction for £80).
More recently a WWII period Panerai Kampfschwimmer (diver's) watch bought in another auction for £10 made £29,000. Military watches carry a premium and if the owner is well known documented hero much more so.
Pocket watches must also be noted with earliest example having been made in Germany in 1510. Some of the best come from Switzerland and the UK. It was selling an 18ct gold full hunter that I had the most unexpected call of my career. Coming from the Helmand Province I was speaking to a captain on a SATPHONE who wanted to buy it for his son's 21st birthday.
