Double impulse escapement

 By: Chris24 : May 24th, 2023-06:55
Anyone know which movement is this ? ...  

There are only two

Lederer's in this case

More like 7+

Double direct impulse=something pushing on balance in both directions at near 90deg, Omega coaxial (and Daniels), Voutilainen 28, FPJ CO, UN Freak, and a few more all qualify.

Not the Omega or Daniels co-axial, but the others could qualify, yes.

The co-axials are a trade-off and only have one direct impulse--the other is indirect. A little study will confirm this. It is confusing because the co-axial is marketed for its direct impluse. The new Seiko escapement is similar. The natural escapements,... 

My bad!

Got the definitions wrong, you're correct. That said the Omega is indirect but the indirect impulse is imparted with not much lower mechanical efficiency so I think of it as "the same".

No worries! We are all trying to understand the watches we love.

And, of course, the Omega co-axial is quite an accomplishment!

Oh, it's a LF "echappement naturel" in the photo
