Explained: Barrels, Mainsprings, and the Trade-off Between Power Reserve and Energy

Every mechanical watch employs at least one mainspring barrel as its energy source. When a watch is wound, the coils of the mainspring tighten, storing potential energy which is then slowly released through the gear train to the escapement. The mainspring is enclosed in a toothed barrel, essentially a drum covered by gear teeth. As a result the barrel is often considered to be the first wheel of the going train.  Although one is the norm, two or even more barrels can be employed, typically to generate more energy. Double barrel movements usually feature two mainsprings kinematically linked in one of two ways: in parallel or in series. The number of mainsprings, energy stored, and power reserve are illustrated with equations (1), (2), and (3): As described by equation (1), the energy of a single barrel E is a function of its torque, angular discharge velocity and running time (autonomy). Linking two identical barrels naturally means having twice the energy, so 2E. By convenient association, equation (2) exploits the available energy to double the torque sent to the gear train, while equation (3) takes advantage of the total energy by doubling the running time.  Parallel barrels The parallel arrangement of barrels embodies equation (2), which delivers twice the torque, increasing the energy available to run the movement (but not increasing the running time). Here two barrels unwind at the same time on a centre pinion connected to a second mobile of the going train. An embo...

New Release: Louis Moinet Astronef Techno Unique Piece Featuring Two Flying Tourbillons and a Eye-Catching Iridescent High-Tech Silicon Wafer Dial

The ever-changing colors of the silicon wafer dial on the Louis Moinet Astronef Techno are not caused by light reflections but by iridescence. This is the phenomenon of a surface changing color as the angle of view or the angle of illumination changes. But there is much more to this unique piece watch than a stunning dial.

Conspiracy Theories and Myths: JFK Assassination by CIA, Moon Landing Faked, 911 an Inside Job, Lemmings Jump of Cliffs, and Rolex Restricts Supply to Boost Prices

The (or at least one) definition of Faith is a strongly held conviction or belief that is not based on proof. Faith in a conviction is a powerful force that can bond many people together for good or for evil. Ian Skellern debunks a few falsehoods, including Rolex deliberately limiting supply.
