New quartz movement issues

Hi Guys I have replaced a Ronda 715 quartz movement for a Burberry watch. The new movement came with a battery and I noticed this little contact bridge? Where does it go to get it going? Can't see it on the old movement either. Seller mentions battery is for bench testing only. 054edeff97217c8c31d507fc9a59ae70.jpg

That extra parts sits on the cannon pinion or minute wheel . To hold the hour wheel in place.  But as @jdm says the screw next to the battery is missing. And there are a lots of fngerprint on the movement. Strange if a NOS movement would come with a battery for testing. But if the movement is okay. take the screw from the old movement.

The extra parts is just for the box and is removed before assembling .

    • Update, I discovered that I could change the mainspring by removing the arbor and sliding it out from between the front and back plates. So I put a new mainspring in. This it what I  get over a 7 day period After winding                                          amplitude is 1 1/2 turns plus a few degrees.                                                                        ie just over 1 1/2 turns. 1 day after winding     gained 1 sec      no amplitude check. 2 days after winding   gained 1 sec      amplitude 1 1/2 turns                                                                                                              i.e. it lost the few extra degrees 3 days afer winding    gained 3 sec     no amplitude check 4 days after winding   gained 5 sec     amplitude 1 1/2 turns                                                                                                               i.e. unchanged 5 days after winding   gained 7 sec     no amplitude check 6 days after winding   gained 16sec    amplitude just over 1 1/4 turns 7 days after winding   gained 24sec   amplitude 1 1/4 turns. From  Based on video inspection, I am getting full pallet lock. So, my data seems to be at odds with the statement "swing of a balance wheel has nothing to do with the rate". However, I have noticed the banking posts are not controlling the lever position on the right side.  I may have some work to do here.
    • I can't tell whether or not some stem is stuck in the crown, I  think so though.  If the crown is stainless steel you could try alum to disolve the stem of try drilling it out. If all else fails, buy a new crown. 
    • Does anyone use the x5 eyepieces,  when i use them on my different amscope , the magnification changes to x5 but the field of view remains exactly the same as the x10, so nothing gained. The optical lenses can't be swapped out or at least they are not available as far as i know. 
    • I think maybe we're all a bit dim @ManSkirtBrew 🤣 99% of the time I'm working with the 0.5X Barlow, so mags from 3.5X to 22.5X. When I need a close up of a pivot or jewel, I take the Barlow out, and even put in the 2X Barlow, but it's a nuisance. So like you, I had that D'oh moment, why don't I just use 20X eyepieces (WF20X/10). They take seconds to change, and you keep the working distance. The only downsides are lower field of view, and less brightness.  
    • At the lowest magnification, I can just get all of a normal wristwatch size movement in field. For some things it's too much magnification, but the nice thing about the eyepieces is they only take seconds to swap in and out. I'm genuinely surprised I've never read about anyone else doing it, to be honest.
