I used 50; it looked about right. ETA is getting Rolex like in their way of doing business.

 

Thank you!

 

Does anyone know the lift angle of the H10?

50°

 

Thanks!

 

The H-10 is a Hamilton-branded ETA C07.611

Caliber H-10

 

I was timing two new H-10 watchs. Looking for the lift angle is how I found this old trhread. Calaber Corner does't list a lift angle for the H-10/C07.11. ETA is keeping things secret since the Old Man died and his kids are running the Swatch show. The H-10 is "based on" the ETA 2824-2 but they have enough differences that they may not have the same lift angle.

ETA 2824-2
28,800 bph, 4Hz
Power Reserve ~38 hours
Regulator Etachron

H-10/ETA C07.111
21,600 bph, 3Hz
Reserve 80 hours
Regulator screws on the balance wheel; see picture.

These are the readings I got today. Not to shabby for a machine regulated movement. The manual is especially good.

H-10 automatic
Dial up -3 seconds a day, 266 degrees amplitude, beat error 0.4 ms
Dial down -2 seconds a day, 273 degrees amplitude, beat error 0.0 ms
Crown up -4 seconds a day, 288 degrees amplitude, beat error 0.8 ms
Crown down -6 seconds a day, 227 degrees amplitude, beat error 0.0 ms
Crown left +5 seconds a day, 235 degrees amplitude, beat error 0.6 ms
Crown right -7 seconds a day, 239 degrees amplitude, beat error 0.3 ms

H-10 manual
Dial up +1 seconds a day, 290 degrees amplitude, beat error 0.1 ms
Dial down +3 seconds a day, 288 degrees amplitude, beat error 0.1 ms
Crown up -2 seconds a day, 245 degrees amplitude, beat error 0.3 ms
Crown down +3 seconds a day, 250 degrees amplitude, beat error 0.3 ms
Crown left 0 seconds a day, 247 degrees amplitude, beat error 0.1 ms
Crown right -1 seconds a day, 251 degrees amplitude, beat error 0.3 ms

 

 

This is a way to find the lift angle when it is not known.

 

BTW: The H-10 is an ETA C07.611 and has some distinct differences to the .111 version.

 

I stand corrected. Good to know the H-10 and I assume the H-50 doesn't have a plastic escapement.
