It´s a bad picture but perhaps someone can tell me what kind of escapement this is?

I don't know if it has a name. It looks like a variant of the pinwheel escapement that is often found in Jeweler's Regulators, only with very few pins on the pinwheel.

Does the pallet on the right pivot? How long is the pendulum? What's the rest of the clock look like?

If I had to guess, with such a paucity of information, I'd say possibly a form a Coup Perdu.

It seems to be a French Portico clock. This one is very nice and unusual. I haven't seen this kind of visible escapement before. Thanks for sharing!

Indeed an unusual escapement. Could we see the movement?

As Uhralt says, thanks for sharing - it's good to learn of new (to me) things.

It’s certainly looks like a pinwheel type of escapement. And from what I can see it’s a Portico style clock. It has a calendar day and date in the 2 side sub dials.
I’m presuming the centre hand is a seconds hand? I’m wondering if it’s actually a mock visible escapement?
San you post pictures of the entire clock, rear view of the movement and side views of the movement? This would help in trying to answer some questions.
Cheers,
James

I don't see a reason to doubt the escapement. It looks workable to me. It's a very interesting pin wheel design though. It would be interesting to know who made it. I'm guessing that it's pretty rare - maybe even a prototype.

I’m questioning it only based on it having 5 pins and a rough drop of 8-10 inches! That pendulum is going to to be swinging mighty fast! or slow!
That and if you look at it closely it’s got a very odd hook or tip on the right side of the fork? Not to mention no support for the fork?
Doubting, No. Questioning and asking for more pictures to try and establish design, Yes.
I was only hypothesizing as to whether it functioned or not.

They had a portico clock sell in Dallas late last year with a similar dial configuration. It had a constant force escapement. The pictures weren't very clear, but it did not look like this escapement.
