A few months back we saw the new Girard-Perregaux Neo Constant Escapement, albeit a one-off version designed for this year?s Only Watch charity auction. Now GP has released the ?standard? production (if you can call it that) version of their new and highly sophisticated constant-force escapement watch with dual-wheel escapement. Girard-Perregaux debuted the prototype for their first Constant Escapement watch back in 2008 with the production model coming several years later in 2013.

If you haven?t fallen deep into the horology-nerd rabbit hole, a constant-force escapement is essentially a mechanism designed to ensure consistent accuracy. This had typically been done with either a rementoir or chain and fusée mechanism, but Girard-Perregaux?s Constant Escapement simplified things by actually integrating a constant force mechanism within the escapement. Essentially, the system consists of a flexible blade spring that stores and releases consistent force to the balance wheel and a double escape wheel system that replenishes the blade spring?s tension. It?s almost ingenious in its simplicity, but this was no simple feat and there is a reason we haven?t seen imitators. While the double-wheel escapement of this new iteration is largely the same, there are some slight updates like a new arming rocker which has a locking mechanism via the central lever.
Where the Only Watch edition was done in all pink gold, the new generation of the Girard-Perregaux Neo Constant Escapement c...
