Important Notice regarding importation into the United States of Rolex watches
Sotheby's cannot arrange for the delivery of Rolex watches to the United States because U.S. laws restricts the import of Rolex watches. The buyer or a designated agent may collect the property in the country of sale."

One of the hallmarks of the Time Museum was Seth Atwood's vision to assemble a collection that would illustrate the history of time measurement in the most comprehensive manner to date. His quest did not stop with the horology of long-gone masters but would subsequently also include his patronage of living horologists, such as George Daniels, Anthony Randall and Richard Good.

The present lot by Richard Good is a further development on the double axis tourbillon created by the renowned horologist Anthony G. Randall (1938-). Randall developed his double axis or 'Tumble Tourbillon' per commission for Seth Atwood, which he later patented in July 1982. For more information, see lot 670, sold Masterpieces From the Time Museum, Part Four, Vol. II, October 13 & 14th, 2004.

The idea behind Good's triple-axis tourbillon, which Randall writes in his book, The Time Museum Catalogue of Chronometers, was to "take the idea of the double-axis tourbillon a stage further and proposed a tourbillon rotating about three axis at right angles. The intention was to make a mechanism that would entirely eliminate positional errors associated with a portable timekeeper. The first example to be made was built into a carriage clock... One of the chief technical problems of the triple-axis tourbillon is the greater degree of complication and especially the extra gearing required, as compared with a single or double-axis tourbillon. The amount of residual error of position to be corrected by the extra axis of rotation should not amount to more than seconds or fractions of seconds per day... The effects of gearing errors on the balance and spring are largely removed by the provision of a constant force escapement."

Interestingly, although Seth Atwood commissioned his Triple Axis tourbillon to be developed for a marine chronometer, Randall writes, "In this particular example, suspension of the timekeeper in gimbals entirely negates the advantage to be obtained from the tourbillon during normal running," thus would seem to be counter to the principals that Good would use in developing this piece.
