It has been years since eta offered the complete balance. If your bridge is clone then I think you should use a clone balance assy. If it' is gen then a gen balance. If you want to send it to me, I will install the balance for you, just pay return shipping. If you want to try it yourself, this is a small tip that may help. First,  install the balance on the base plate. Be sure the jewel is in the pallet fork and the bottom axle is in the baseplate jewel.  Then gently put the bridge on. Be sure it's in the top axle on the balance. When you install the bridge, be sure that the hairspring is in the brass part of the speed lever.  Then put the screw in the bridge and tighten. you now have everything in place. The stainless bar on the hair spring is now close to the beat lever. Take your tweezers and set the stainless bar in place in the lever. Then use your tool to push it on the lever. If it's incabloc be sure and pull the stem out to the stop position after the balance is in place. Push the stem in and set the speed and the beat. Hope this helps.

eta does furnish the hairspring with the axle installed.

Generally a full wind will be 50 turns. However, even at 1/2 wind the rotor should keep it running. Probably a weak main spring or a defective rotor. Good luck

Alligoat is correct. Use a tiny bit of loctite on the stem. When you release the stem, add a very slight outward pressure and barely, and I mean barley press the pin down. Don’t force the stem back in. Push in gently while rotating it slightly .

Just to confirm, you’re sure the balance has not popped out of the pallet fork. Easiest way to ck is to flick balance wheel and see if it rotates in both directions. To confirm, take a pair of tweezers and gently rotate the balance in both directions. If you feel it stop going in one direction, loosen the balance cock and reinstall the balance wheel into the pallet fork

I too have had this happened. I take my finger nail and put it on the mainspring tub gears and then rock the the tub back and forth. If the balance is in the pallet fork, it may start. Make sure the the balance hasn't popped out of the pallet fork. I"ve done that on a dozen eta's in the last year. Something binds up and I cannot figure out why. Try that first . Horologist is correct. Remove the pallet fork and make sure the drive train spin"s freely. Good luck.     The balance wheels are very tricky. With the balance assy on your bench, and the hairspring up,  lightly flick the balance wheel. It should run freely for around 15 seconds. The 15 seconds is my rule of thumb, not a rule applied by industry horologist. If it doesn't it could be the hairspring is bad. Look at the coils on the hairspring and see if they are evenly spaced. If you have another balance assy to try, do that.  I got some advice from my rolex dealer friend years ago about hairsprings. He told that sometimes the ones that look the best won't run at all, and sometimes the ones that look the worst perform perfectly. It's a crazy crazy world when it comes to hairsprings. They can drive you insane!  LOL

Just a note on the crystals. If you ck your crystal that you use, make sure it's not loose on the rehaut. Also, when you press the retainer on, try to keep it as level as possible. If one side goes down before the other, it will usually crack the crystal. Good luck.

They cannot. The only thing you can do is remove the marker, cut one foot off, and reinstall with glue. Very touchy process. Decide which foot to cut before you do it.

Correct. The slot in the movement ring is for the stem. If you put it in the wrong way, the stem wont go in. The pics are correct.

I agree with Nanug, the 2783 is a workhorse. I have one in stock and it seems very powerful. Just won't die. It's very old but has good readings on the machine .  Not a bad choice for any build.

good job!

It's hard to answer that question. The SA3135 will take a gen dial. Most of the  A3135 that I have seen are a modified eta's. It's hard sometimes looking at the pictures of the movements to determine what the base is that they started with. There is no mistaking an SA or a yuki. They do dress some eta"s to look like a rolex. Feet position will tell you which movement you're working with.'Good luck

From the center of the sweep second to the of the factory date wheel is 9.53mm. From the center of the sweep second to the center of the numbers with the overlay on, it's 8.55mm. Hope this helps

I have a gen black dial if you ever want to change.

Loved the song when I first heard it. I would sing along every single time I heard it. 

I use a paste I mix from liquid hand soap and baking soda to clean and shine gold plated reps. Use a soft tooth brush with warm water and clean the watch good top and bottom. I think you will be pleased with the results. Good luck.

The area that leaks in most watches is the crown. The case tube o-rings, or the crown is not tight enough. I don't think you should take a gen into salt water, let alone a rep. But, that's just my opinion. You may want to have it looked at inside to make sure there is no damage. Good luck.

good luck. Hopefully it will be a minor repair.

I never recommend this, but have you tried rolling the time backwards. Sometimes it will reset. If everything is working on your watch, never roll time back more than a few minutes. Never at midnight

I usually taper the hole for the case tube. Most of the cases don’t have a taper, they are just flat. That will keep your tube original. 

I want to order 2 subs, but I'm not sure I'm on their actual site. Any advice?

I have a used one. complete movement, nearly

Nice datejust!!
