While taking the movement apart I felt a strange sense of déjà vu dealing with the escapement. I knew that I had held that exact pallet fork and balance wheel before. It took me a few minutes, but I realized that this escapement is a dead-on copy of an ETA. To be sure of this I grabbed a spare 2824 that I have on hand, and swapped out the pallet fork. Sure enough, it ran exactly as it should. Upon realizing this I contacted Eterna to find out if the firm made, or purchased, two of the hardest things to make: mainsprings and hairsprings. To their credit they were honest, and they responded letting me know that they purchase these items. While this is disappointing to have found out, it in no way discredits the engineering obstacles that they have been able to overcome to produce this movement. Instead of escapement engineering they put their resources into designing and manufacturing a hugely customizable mass-production caliber. Some other ETA competitors simply cloned ETA movements, but Eterna has created a vastly different product offering that borrows/buys where it needs to. If you wanted to further nitpick, their cannon pinion and driving wheel are a dead ringer for an ETA design, and some other components look similar to some ETA parts, but really it does not undermine their achievement: being able to offer a robust high-quality Swiss movement, at a reasonable price and at high enough production rates to accommodate a coming market shortage.
