Beating inside at 28,800 beats or 4Hz is the SW300-1 which is the Selitta equivalent of ETA 2892. The difference between the 2824 and 2892 isn’t dramatic, however the winding feedback between the two is night and day, where 2892 wins every time. I’m a bit surprised here as this is usually seen in watches with higher price points such as IWC and Omega, before their switch to the co-axial The co-axial escapement is a type of escapement mechanism invented by George Daniels, a British watchmaker, in the 1970s, and is characterized by the use of a co-axial wheel, which is a three-level wheel that replaces the traditional pallets used in other escapements. It uses a unique design that allows the gears to run with less friction, which means that it requires less maintenance and will have a longer lifespan than traditional escapements. Additionally, it is said to be more precise than traditional escapements, this is mainly because of the decreased friction which allows the balance wheel to oscillate more consistently.

I need to get my hands on one of these U50s 🙂
