PATEK PHILIPPE. A VERY RARE LIMITED EDITION 18K WHITE GOLD AUTOMATIC DUAL TIME WRISTWATCH WITH SWEEP CENTRE SECONDS, DATE, DAY/NIGHT INDICATOR, CERTIFICATE OF ORIGIN AND BOX

To the best of our knowledge, the present example has never been offered in public before.

Released in 2017, the sporty and elegant Aquanaut Travel Time reference 5650G is unlike all previous Patek Philippe Advance Research models. Made in a limited edition of 500 pieces in white gold, its purpose is to showcase two important horological innovations - the new flexible mechanism used to set the second time zone that operates without conventional pivots and the ‘Spiromax’ balance spring made of ‘Silinvar’. The Aquanaut Travel Time reference 5056G is the first wristwatch to feature both these important state-of-the-art technical advances. The steel flexible mechanism for adjusting the GMT hand forwards or backwards, called “compliant” by Patek Philippe, uses a frictionless and lubrication-free system of integral leaf springs that reduces the number of components needed compared to Patek’s traditional GMT mechanism from 37 to 12. With the use of the revolutionary Silinvar Spiromax spring (updated with a new inner terminal curve for 2017), Patek Philippe has ventured one step closer to perfection - the spring is isochronous regardless of temperature, movement orientation or magnetic presence and provides an exceptional rate of -1/+2 seconds maximum daily rate deviation.
