Chemically, quartz is a specific form of a compound called silicon dioxide. Quartz is a piezoelectric material: that is, when a quartz crystal is subject to mechanical stress, such as bending, it accumulates an electrical charge across some of its planes ...  

I think part of the disconnect that quartz watches suffer is that they have the "Black Box" effect whereas mechanical watches allow us to see and (at least pretend to) understand the mechanism and its effects.

I didn't know that the same “mechanism” or reaction was used on low-end phonograph cartridges: just out of curiosity, what other “mechanism” is used on high-end phonograph cartridges? Best, Emmanuel

Best, Emmanuel

that version needs a small external power supply and the coils shown in Greg's post, to create a magnetic field through which the magnet moves

many, many years but am seriously considering jumping back in with my next watch purchase. Strongly thinking about the Cartier tank watch in quartz, A. never need to wind/set B. Just want to try a quartz watch again. C. No one will be the wiser, and D. It...

…of the watch industry. And the customer is always right, even if the customer has changed his mind, and no explanation for the change of mind is required.

But frankly it’s been practically the last real innovation in the watch world, albeit around 100 years old itself 😂 I often enjoy a nicely done quartz watch, even though those are few and far between 😊👍🏻 Doesn’t quite manage the 5 seconds a year on the cu...

Thanks for the added pictures 👏🏻👏🏻👏🏻

But certainly worth posting.

The shaped quartz crystal absorbs electrical energy as it bends and then returns it as it unbends. Just like how a balance spring stores up energy and then returns it as movement of the balance wheel, once per oscillation. The gross energy thus stored div...
