10BPAC may interchange with 10BPAD, 10BPA, and possibly 10BOAC, which is the base for it.

While I'm not familiar with this exact movt, it looks like the reverser, it has a counterpart and the two sit together and wind one way, slip the other. This particular Bulova movt doesn't have an equivalent, so may be in house? It's from the late fifties, so parts may not be available, you will have to find another movt with interchangeable parts. 

Bulova calls this part 'Mobile d'inversion', or 317D. (Reversing wheel)

Small watch parts dropped on the floor will hid from you for a minimum of 6 months.  After that time  they will re-appear when you are looking for something else.

Some other rules. 

A dropped part will never end up in the canvas shelf of your bench.

If you purchase a replacement for the missing part the 6 month disappearence rule is suspended and the lost part will appear at it's earliest convenience.

That's a pretty big part to lose....not like it's a click spring, a second hand or small screw! You should be able to find it eventually...it's probably in the most unlikely place you can think of....I can't tell you how many parts have simply disappeared from me in front of my very eyes - there one minute, gone the next! It's like a deceased and frustrated watchmaker playing games with us from beyond!

thats is exactly what happened there one minute gone the nextand it fell right in front of me..not like it flew across the room like some part that is spring loaded

Thank goodness it isn't just me! I thought I was losing it. No pun intended.

Dave do you wear one of those apron thingies (sorry about the technical jargon) which kinda makes a little lap tent around you and your bench to catch flying parts for problems like this? I have caught a few flying gears and hands etc... w one of these.   I don't have a pic of one now, but I made one and they were available on internet.  Someone will know the laymans name for this "tool".  It's not pictured in De Carlo's book, but I think he mentions it in the text somewhere.  I made one out of a sheet w/ some shoelaces, and velcro tape of the edges around my bench/work area walls. Now when I break things, I catch most of the flying parts before I throw the movement away.... :)

They are pretty helpful aprons.  I'll see if I can find a link to a pic or something, and PM you so if you want you can make one yourself.  They are great for springing springs etc...  Will

Hey, thats not big. I managed to lose a whole dial. there one minute, gone the next. A nice Bulova wrist alarm one too.....i'll wait another few months and it'll turn up if the 6 month rule applies! fingers crossed

i happen to work in my family room,although on a work bench,but its on top of carpet which makes finding things 50times harder..i was thinking about putting somekind of plastic or something under my chair and bench,the stuff for computer chairs to roll on..has anyone seen or used that metal detector..i wonder what rob used to do working for a watch co...can you just go and get another part? i am sure high end watch co.s would get upset if you kept on losing parts for there expensive movements...

Likewise i have a carpeted floor and it is a nightmare. I have tried plastic covering but they too can be a pain. if you drop a part on that and move slightly the plastic can ping it off anywhere. The best thing i have found so far is a large white towel, soft so when something hits it doesn't bounce, not thick enough to get things stuck deep down in and easy to see things on.

Well, it didn't happen to me, but yes, if you kept losing parts, especially scarce ones, they might have a little talk with you. For example, at Swatch, (Omega, Blancpain, Longines, Tissot, Hamilton, Breguet, etc.)  there is a finite number of old Omega parts available, for the vintage stuff, and once they are gone, they are gone. I hear from my old contacts that they are already restricting intake of vintage Omegas and Tissots. We were very lucky when we were at school, the parts inventory was huge and very unusual. We got millions of parts from various schools in France and Switzerland when they closed down. The school does not sell these parts, but they are available to the students working there. They have the rarest of the rare, and original manuals, too.

Eventually, with practice, you will decrease the number of things you drop. It is critical to use good quality tweezers, and to keep them honed and shaped perfectly. I always use brass or bronze tweezers when handling highly polished parts so they don't get marked in any way. After cleaning, and during reassembly, I always wear finger cots to protect the clean surfaces, and use pegwood to hold down springs while installing them. A pegwood stick, with a sharp point on one end and a chisel tip on the other, is very useful when manipulating yoke springs, etc. If something looks like it can fly up, you can hold it down with the chisel tip while you secure the part with your other hand. (screws, plates, etc) Click springs are especially prone to escaping, as are yoke springs, and the odd ly shaped springs on chronographs.
