Concluding a busy auction season at the Bonhams Fine Watches sale, a Roger W. Smith 18K gold manual wind Series 2 wristwatch once again shattered its top estimate to sell for £516,900.

Jonathan Darracott, Global Head of Watches for Bonhams said; "It was an honour and a pleasure to be able to offer one of Roger’s fabulous Series watches and for it to get the recognition that his pieces are truly the pinnacle of the Watchmakers' art with this exceptional price at auction for a Series Two.”
