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??

 

Dennis.

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.

      I'm going to be setting up a decent little workshop here at home.

      By Michael1962 · Posted

      Well I put the spa on Gumtree (selling service) to try and sell it as it only needs a recirc pump to get it going. However, it weighs circa 250kg, so there's 4 fairly strong guys, and I would have to remove the sliding door in the room completely to be able to get it out, as well as clearing out a multitude of potted plants and the Alfresco outdoor setting to be able to get it out. Then move nearly everything in the back of the garage to be able to push it through to the front of the house. I would also need to hire furniture skates to be able to shift it around as carrying it is out of the question. Then someone would need a trailer to get it to their place as you won't get it on the back of a ute. So, the only answer is, out with the reciprocating saw and cut it all up into manageable pieces. Crying shame as it is in really good nick. I was only asking $1,500 and only got two bites, but it would only take something to go wrong with removing the sliding door etc that everything I make on the sale could go out the door on repairs etc. It would have been nice to be able to turn it into tools etc, but que sera sera. I don't know about the rest of the world, but there just seems to be very little interest from people wanting to buy things secondhand.

      I would like to see the movement. The watch is the movement. Anyone can print a name on a dial and sell it as "the maker".

      What are these Seitz B-Jewels?

      By VWatchie · Posted

      Thanks for your answers! There seems to be a contradiction between these two answers, so perhaps I need to clarify. The flat and convex jewels look identical on the side facing away from the pivot shoulder. That is, there is an oil reservoir. I don't know if that changes anything but I thought it was safest to clarify since I didn't include a picture of the jewels from the opposite side.

      unfortunately paying attention to details bumps up the cost. Which is why they shortchange on manufacturing steps if they can.

      Thank you for your introduction and welcome to this friendly forum. We all look forward to your contributions and continued involvement.  When it comes to tools buy the best you can afford a good set of watch makers screwdrivers if you look after them will last you a life time. I recommend Dumont tweezers Number 3 and number 5 for fine work, you can build up from there. You will need different strength eye glasses. Some now like to work using a microscope. Pliers the box jointed ones are best they don't go out of line.
