ultimate 6497

[robideaux]

hey The Zigmeister, do you know if it would be possible to combine the best features of both the most recent eta 6497-1 with swan neck with the CN 6497-2 copy? the cote de geneve on the cn movement is awful, there is no swan neck, and the letters are crooked. what i would like to attempt is a 21,600 beat 6497-2 with the nicely decorated parts (cote de geneve bridges, swan neck, winding gears) from the eta 6497-1. do you think they would be interchangeable? i know you have handled both movements so i thought i would ask. i hope you can give me your best approximation! thank you for all prior insights into the world of horology!

Thanks for the question.

I have not tried to do this type of swap between these movements so I can't say for sure if it's possible.

The biggest issue is going from 18,000BPH to 21,600BPH, the gear train and balance etc are not interchangeable between these models, but I am not sure if the locations of the gears are the same. In other words, can you take the guts from the 21,600 model and put them into a 18,000 movement...

Although I have worked and serviced both types, the only way to know for sure if this is possible, is to give it a try.

If you have the movements and are willing to give it a go, I am willing to see if it can be done.
