The lot is sold in the condition it is in at the time of sale. The online condition report is provided to assist you with assessing the condition of the lot and is for guidance purposes only. The images of the lot also form part of the online condition report for the lot provided by Sotheby's. Any reference to condition in the online condition report does not amount to a full description of condition. The online condition report may make reference to particular imperfections of the lot but you should note that the lot may have other faults not expressly referred to in the online condition report of the lot or shown in the online images of the lot (for example, the online condition report may not specify mechanical replacements or imperfections to the movement, case, dial, pendulum, separate base(s) or dome). Watches in water-resistant cases have been opened to examine movements but no warranties are made that the watches are currently water-resistant. The online condition report may not refer to all faults, restoration, alteration or adaptation but rather the online condition report is a statement of subjective, qualified opinion (for example, information regarding colour, clarity and weight of gemstones are statements of opinion only and not statements of fact). Please also note that we do not guarantee the authenticity of any individual component parts, such as wheels, hands, crowns, crystals, screws, bracelets and wrist bands, since subsequent repairs and restoration work may have resulted in the replacement of original parts. In addition, certain images of the lot provided online may not accurately reflect the actual condition of the lot (for example, the online images may represent colours and shades which are different to the lot's actual colour and shades). For these reasons, the online condition report is not an alternative to taking your own professional advice regarding the condition of the lot.

We reserve the right to remove these bands prior to shipping.

During the 1950s and 1960s, after the dawning of the atomic age, the field of horology had to allow for the introduction of electronics. Patek Philippe, consistently striving to be at the head of timekeeping innovation, developed their first battery operated solid state clock during the early part of the 1960s. The clock system of these modules was designed to be constantly regulated by radio signals from the atomic clocks in the Parangins Observatory in Geneva. Single modules, such as the present lot, were often ordered by Kreutler in Germany; themselves specialists in master clock systems for industrial plants. This rare PC based system by Patek Philippe represents one of the most state of the art timing systems of its day. The master module can control almost an unlimited number of slave clocks. The Computime unit receives 77.5kHz radio signals and passes them to the master clock by means of an RS-232 port. The accuracy of time was exceptional, exhibition a margin of error +- 10 milliseconds.
