The module is likely a Quantum SA.45s. Very small for an atomic clock, huge for a watch-type object. Low atomic clock accuracy (5 * 10-11), great for such a small timepiece. The module consumes about 120 wW .. this means a full smartphone battery would give maybe 50 hours of continuous service.
The best uses are probably portable GPS-denied applications that require precise synchronization. Underwater exploration.
The No. 10 pocket watch is more for the personal style statement of a wealthy watch collector.

Use of optical imaging for medical and scientific applications requires accurate quantification of features such as object size, color, and brightness. High pixel density cameras available on modern mobile phones have made photography simple and convenient for consumer applications; however, the camera hardware and software that enables this simplicity can present a barrier to accurate quantification of image data. This issue is exacerbated by automated settings, proprietary image processing algorithms, rapid phone evolution, and the diversity of manufacturers. If mobile phone cameras are to live up to their potential to increase access to healthcare in low-resource settings, limitations of mobile phone–based imaging must be fully understood and addressed with procedures that minimize their effects on image quantification. Here we focus on microscopic optical imaging using a custom mobile phone microscope that is compatible with phones from multiple manufacturers. We demonstrate that quantitative microscopy with micron-scale spatial resolution can be carried out with multiple phones and that image linearity, distortion, and color can be corrected as needed. Using all versions of the iPhone and a selection of Android phones released between 2007 and 2012, we show that phones with greater than 5 MP are capable of nearly diffraction-limited resolution over a broad range of magnifications, including those relevant for single cell imaging. We find that automatic focus, exposure, and color gain standard on mobile phones can degrade image resolution and reduce accuracy of color capture if uncorrected, and we devise procedures to avoid these barriers to quantitative imaging. By accommodating the differences between mobile phone cameras and the scientific cameras, mobile phone microscopes can be reliably used to increase access to quantitative imaging for a variety of medical and scientific applications.
The current crop of quad and hexcopters are very maneuverable, but are also inefficient when it comes to distance flying. A tilt-rotor design makes more sense if you're after distance and tight landings and takeoffs. NASA has a ten motor UAV to investigate the space.
For several years people have speculated about the use of small auxiliary electric motors in bicycles - could a motor and battery pack be small and powerful enough to make a difference in a bike race Here's an example of what can be done..
