What distinguishes it
Look beyond the reference.
One everyday distinction from the SW510 is date setting: ETA specifies a correction pusher at 10 o’clock for the 7753. This affects how the watch is operated and how its case is designed.
For the enthusiast
Its chronograph records seconds, minutes and hours. The 54-hour figure follows ETA’s current portal; verify the watch’s generation when comparing historical specifications. A manufacturer can choose its own decoration and regulation, so calibre identity is only one part of the complete-watch story.
