Hublot Masterpiece Watches Now, I should clarify here that in watchmaking the term constant force refers specifically to the escapement, that clever little mechanism responsible for transferring the power stored in the mainspring to the balance wheel (the latter of which is responsible for timing). To create the power in the first place the spring either needs to be wound manually by hand or, if it’s an automatic movement, through the miracle of kinetic energy.That doesn’t mean this traditional method is satisfactory however. You have to remember that at their core watchmakers are inventors and creators (why else do you think they wear the white lab coats?) and so they love nothing more than to come up with innovative solutions to age-old problems. And they don’t come much more age-old than this. In fact, according to Girard-Perregaux the issue of constant force has plagued watchmakers since the dawn of time. I’m not sure if it goes back quite that far but there is definitely history there of famous watchmakers trying to solve this very issue. So, what have Girard-Perregaux done that is so different?
Richard Mille RM 069 replica So far so good, except there’s just one problem, how do you make sure the rate of energy delivered as the spring unwinds remains constant? The simple answer is that you can’t, at least not when using a traditional lever escapement as most mechanical watches do. Like anything that is tightly wound, the mainspring is bursting to unwind as soon as it given the chance, thus delivering a strong wave of energy at the beginning of the cycle. Inevitably though the rate of energy delivered to the balance wheel will at some point begin to slow. Now, admittedly the effect of this is almost imperceptible, with a degree of ‘balancing-out’ naturally occurring, and so most people are willing to tolerate a +/- 5 second difference.Well, unlike previous solutions, which found ways to better regulate the flow of energy from the mainspring (i.e. making it slightly more linear), the team at GP developed a way to make it absolutely linear. That means there is no drop in amplitude over time, regardless of the remaining energy in the barrel. To do this, they re-envisioned how an escapement should look and work, which included placing a remarkably thin (6x thinner than a human hair), vibrating silicon blade right through its central axis. The science behind it is probably a bit technical for a watch review but essentially this blade is able to store energy up to a certain threshold before snapping back in the opposing direction, pushing the balance wheel forward, counteracting the variable energy of the barrel and releasing the same amount of energy simultaneously.
