The ETA caliber 2824-2 is perhaps one of the most well-known and most recognized movements in the watch industry. It has been in production since 1982 and was based off of the original Eterna caliber 1427. The “-2” designation indicates the generation.
The 2824 is considered to be a “workhorse” movement by many watch enthusiasts.
