I have an ETA 2824-2 Top Grade movement that I purchased recently from a supplier in Switzerland that I didn’t end up using for a project. This is the Top Grade undecorated version. The upgrades that the Top Grade version has over the standard and elabore are: -Adjusted in 5 positions -Glucydur balance wheel -Incabloc shock absorber -Anachron hairspring -red rubies (vs polyrubies) If you have a watch with a 2824, Sellita sw200 or STP1-11 this could be a nice upgrade. The top grade is the same as Chronometer grade, without the certification.
