555.415 interchangeable?


Recommended Posts

I have a Tissot with a ETA 555.415 movement, that is water damaged.

I have decided to replace the movement, as the ETA movement is pretty low cost.

But the 555.415 is not as easy to find, as some other ETA movements.

So my question is, is there other ETA models that are directly interchangeable with the 555.415??

The correct replacement for this is not 255.112.  This is the wrong diameter and thickness.

555.415 = 955.412, 955.412 is the same movement essentially just a few updates over many years.

 

decisions, decisions....

My bad. Didn't do my research properly there.

Hope i am right this time. Three first are for day at 6 a clock. if you have the date window at 6. Last two is different heights. On the H1 the hour wheel is 1,06 and H3 hour wheel 1,55.  There is also a H0 https://boley.de/en/caliber/watchmovements/eta/4001.955-412

Follow these steps...

Does it have a second hand...  Yes = 3 H = 3 Hands, No = 2H = 2 Hands

Where is the date...   At 3 O'clock = 3D, at 6 O'clock = 6D

Remove the old hour wheel and measure the height with a vernier gauge, if it is between 1.02 and 1.10 then it is normal Height.  Otherwise you will need a high or low version.

75% of the time you will have the most popular version which it 955.412, 3H, 3D  (Normal height, not HT0 or HT3)

So that is 955.412, 3 Hands with the Date at 3.  Suppliers all round the world will stock this version. 

 

Simples :-)

The movement i am replacing is has a H1 hour wheel, so that is sorted.

I must be slow... because the difference of D3 or D6 movement is obviously what direction the numbers on the date ring has. :hocky:

Thx.

Hey There @Emancipator. No you're not slow...it takes a little time to figure such things out. Check out @rogart63 explanation of the movement codes.

    • Welcome to the group Stirky. You can search for just about every subject in the craft here. Don't be afraid to ask if you can't find the answer that may have already been covered ( some ad nauseum LOL ). You don't have to buy Bergeon to get good quality. There are many decent mid-range tools available that will last you a lifetime. Cousins would be a good place to start . Cheers from across the pond ! Randy
    • I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!
    • Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.
    • So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
