George Daniels Co-Axial Chronograph – £463,000
This rare Daniels Millennium watch is one of only 47 pieces produced in yellow-gold and it was delivered in 1999. The Co-Axial was the first practical, new escapement since the invention of the lever escapement by Thomas Mudge in 1755, representing an important advancement in the dynamics of the watch escapement. It was revolutionary for a big number of reasons, but most importantly it allowed for longer times between servicing.
