Meg-dollar time machines: An diminutive clock that syncs with your wristwatch
8 years in the making, and with only three pieces in the known universe, Urwerk's AMC costs a cool Southward$three.8 million and features an atomic clock plus a wristwatch that tin be synced with it.

In the earth of serious watchmaking, the mechanical and the electrical accept always been at opposing ends of the spectrum. Sentinel purists will debate that only the former tin can exist considered 'existent' watchmaking and information technology would be blasphemous if the two elements even come close to one another in a picket.
Thus, high-end watchmakers have more often than not steered clear of the latter, instead, preferring to focus on the traditional side of watchmaking. None of them will ever think of somehow combining the ii, as the idea of a mechanical/electronic lookout man at the high-end toll signal seems rather preposterous. Unless you are Urwerk, that is.
With Urwerk considered the 'mad scientists' of the watch industry, preposterous is exactly what they – founders Felix Baumgartner and Martin Frei – are gunning for. The Urwerk AMC is a combination of a mechanical wristwatch and a 35kg sentinel winder that, by the way, is besides an atomic clock (AMC stands for Atomic Chief Clock).
How the AMC works is similar to Breguet's Sympathique clock of 1793. The thought is to utilise a more than authentic only stationary base clock to help proceed time on the satellite timekeeper (in Breguet's case, it was a pocket spotter), adjusting and regulating it whenever the unit was 'docked'.
Urwerk took this step one step further. For the base unit – chosen an Atomolith – Baumgartner and Frei decided to become with the most accurate clock to date, an diminutive clock. Not only does the Atomolith (doesn't the proper name sound similar something simply a mad scientist could come up up with?) house the atomic clock, it also has a GPS system for synchronisation.
To illustrate just how authentic atomic clocks are, consider this. The Superlative Chronometer certification from Rolex is considered to be 1 of the all-time standards for traditional mechanical watches. That has a deviation threshold of +two/-2 seconds per day. Loftier accuracy quartz movements like the Grand Seiko'south Calibre 9F is authentic to +10/-x seconds per year. The Atomolith offers a difference rate of i 2nd every 317 years. Yeah, pretty hard to beat.
So how does an diminutive clock work? The basic principle of timekeeping hinges on the regulator. In a mechanical watch, it is the residuum jump that plays this office and typically oscillates at 4Hz or 28,800 beats per hour. In a quartz watch, the namesake crystal is the regulator and generally clocks in at 32,768Hz.
With an atomic clock, the measurement of the electron transition frequency inside an atom becomes the regulator and in the case of the Atomolith, a Rubidium isotope is used. The frequency of Urwerk'due south atomic clock (fabricated in collaboration with Swiss business firm Spectra Time) is a gob-stopping 429,000,000,000,000Hz.
All of this would mean nothing if the diminutive clock, housed in a case of solid aluminium, could not communicate with the portable AMC wristwatch. The clever bit is designing the watch and then it could be wound, synchronised and have its regulator adjusted without the need to open the picket case.
Urwerk achieves this procedure past allowing the Atomolith to interact with the AMC via the crown and two boosted pushers. Apart from setting the time, this procedure of interaction betwixt the Atomolith and AMC also adjusts the regulation rate and so theoretically the picket will get more precise each time it is docked.
The mobile unit of the AMC offers a 4Hz movement with a Swiss lever escapement and a linear balance wheel with lxxx hours of power reserve. Another fun fact: The AMC has an oil change indicator – a feature that Urwerk has used in previous models – which makes a full rotation in a piffling over four years, signalling to the wearer when it's fourth dimension for the scout to be serviced.
