![]() Just placing a mechanical watch on a loudspeaker could expose it to enough of a magnetic field to alter its performance. Traditionally, hairsprings have been very susceptible to magnetic fields. Instead of gravity providing the restoring force, a tiny spring that is barely the width of a human hair provides the restoring force. A pendulum wouldn't work in a mechanical watch, so we instead use an oscillating balance wheel. The grandfather clock's pendulum swings back and forth, with gravity providing the restoring force. To understand how important the hairspring is, consider a grandfather clock. ![]() The hairspring, when coupled with the balance wheel, forms the regulating organ of a watch movement. An example of this is the Blue Parachrom Hairsprin g, introduced by Rolex in 2005 after five years of intensive research and development, and now used in the Rolex Submariner. Rolex works continuously to update its mechanical movements, resulting in a level of refinement that is rarely seen from other brands.

Over the following decades, Rolex continued to improve the Submariner with updated movements, the introduction of sapphire crystals and increased water depth ratings to 300m. ![]() While the no-date Submariner models have always retained their stainless steel construction and black bezel and dial colorway, Rolex developed the Submariner Date collection into a more luxurious lineup by welcoming full gold and two-tone gold/steel models into the mix. 1680 included a date window on the dial at 3 o’clock, complete with a magnification lens called the Cyclops that protrudes from the crystal above it. Unlike earlier iterations that only displayed the time, the Submariner ref. The late-1960s marked a major milestone for the Submariner, as Rolex expanded the collection to include the very first Submariner Date model. ![]()
