telling a 2813 from a 2836

Read this on another forum:

Rotate the crown 1 full turn. If it moves 45min then it's a ETA or Clone 2824/34/36-2. If it moves 1.5 hours, 21J

But once you've owned both you can hear the beat and can tell by simply winding the crown to charge.

Winding is an instant tell if it´s a 2813, each 1mm forward will have several clicks, on the 2836 maybe 1 every 2mm.

If shaking the 2813 and than stopping the rotor will continue to rotate audibly for a while, on the 2836 it will be less

audible and soon stop.

When looking close or under light the 2813 will always visibly stutter and hesitate with 5to6 ticks per second, the 2836

will look balanced and smooth (8 ticks per second). With a lupe it´s possible to count the ticks.

Plus the crownrotation/ time advancement like Junbug said with the 2836 advancing significantly less.
