304 degrees dial up lol



This is on the border of TOO much. So it turns out the best result was from using parts from both movements? Interesting

Delta should still be in the 9 second range as usual (that's the time between the fastest and slowest position). From what I understand, out of the 6 main positions, you try to lean towards dial up, crown left (6 up), crown down (9 up) then narrowing down to 0/0 seconds per day, for best real world accuracy

This is the spec sheet for the original ETA 6497-2



So unless trying to get COSC certification, they test these 3 positions: CH = cadran (dial) high, 9H = 9 high, 6H = 6 high

Max delta for this movement is 15 seconds, so we're already ahead of that. We see the max amplitude is 320 so we're safe there.

Oh BTW I also modded my loupe by poking a few holes in it with a soldering iron. 2 wasn't quite enough, but 3 works great! I am going to go back and file the rough spots down.

It makes it a million times more usable, but I still prefer the 3.5x mag for both eyes when doing general assembly and disassembly. 5x and 12x really helps when doing fine work though. I will eventually get a microscope for that
