I’m no expert, but my quick research suggests you’re correct. Reliable, accurate, used in many expensive timepieces. That’s why I’d like to use the same one if I can make it fit!The 7750 is a standard movement for automatic watches today. You are correct there. But a lot of watches in 2010ish from Panerai, Breitling and others used this caliber in their time pieces
I think it does a decent job.
