Watch nerdery incoming. You have been warned.
A good article from Hodinkee about the new GP constant force escapement was just posted. Although Monochrome covered this horological breakthrough in greater detail some weeks before, the Hodinkee article is a little easier to understand IMO.
Some here might recall mafoofan and I discussing power reserves some pages ago. Some again might recall a particular comment from the foo mentioning that having a huge mainspring exacerbates a problem inherent in all springs - that the spring runs too "hot" initially, then as it winds down delivers energy in a non-linear manner. Since the escapement has no way of "insulating" this effect from the rest of the movement, the fundamental function of timekeeping is compromised.
Make that was
This new GP constant force escapement is absolutely ingenious in its very simplicity. I can remember myself playing with flexible train tickets many years ago (read the Hodinkee article to understand this reference), and even if I were a watchmaker I doubt I would have made the mental leap to actually coming up with this design.
While this new GP watch is not exactly a watch I would buy for its looks, it is a true breakthrough that I think deserves the attention of any person who considers him/herself a mechanical watch lover. And it definitively shows that strange deluded aggressive poster from quite a few pages back (remember him??) that horological development did not
die with George Daniels. Hah!
