Surena watch movement

[RichardHarris123]

Hello all.  

Anyone recognise this movement?  I'm assuming Surena bought ebauche's , like many others but I  can't find much information.

Am I going blind, where did you see that?

Under the balance rim, the FHF is stylized backwards F and normal F with the middle line connecting them to make the H.

 Hi Rich,  Not sure what this  type of gears bridge is called overbridge ? or what, anyway,  AS made a generation  of  movements with similar type of gears bridge. not sure if parts interchange.

Thanks all.  Decided to buy the watch, it's meant to be a good movement.  Chronoglide have a video, I haven't had time to watch it yet.  Here's the front of the watch.

when you see enough of these movements you start to recognize the bridges and other distinct tells, this one was easy because the train wheel bridge has a cut-out for the crown wheel screw, same as the FF25, the balance cock also faces in a different direction than most, some old Brietlings used these movements.....
