ISA 1198 Date ring swap

Recommended Posts

Howdy all

I am replacing the movement in my old Swiss army Lancer watch. ISA 1198. The original date wheel is black. The one that comes with the new movement is white. Is this an easy swap? Is there a parts exploded view or pdf repair sheet for these movements?

It is an easy swap. I guess most calendar wheels are white so maybe it's difficult finding an original black one...

Have you worked on a movement before ? Don't think that there's such a sheet for these movements...

Also, some movements are offered with different day/date wheels (depending on where they are on the dial).

Most have date at 3 o'clock but some have it at 6 o'clock and so on. The difference is the position of the numbers/words.

As the OP mentioned, he needs to port the date ring from the original to the new mov't.
Not a difficult job but I would not advise about doing any experience or specific tools. Even a lost screw can create new, unneeded trouble. Giving it to a watch shop is safer.

    • OK! I was able to get a nice set of timing washers from ebay! And they worked really well. I needed to slow down the movement by about 6min and I put four (=two pairs) of 3-minute washers (rated for the the size of the movement) and it did pretty much exactly that. On one pair of screws, there were already washers. So I added a second washer on those screws. Maybe not ideal, but it doesn't cause any problems. Poise is ok.. not perfect.. but I had so many issues with the watch that I decided to accept it. It's a 90-year-old watch. Delta is around 40 seconds.   
    • I think it is friction fit, there are tools to remove them, cheaper versions are available. You could try adapting some pliers, see my crap drawing.  The pushers are available in various sizes, you could measure once the tube is removed. 
    • The entry jewel's not as bad but seems still too much lock. I do epilame the escape wheel and pallet jewels, then run dry for about 15 minutes, then put 9415 in exit jewel very little at a time and check with backlight how the oil's distributed.  Another question is about capped escape wheels. Should I somehow wear the epilame off the pivots before installing the wheel? I normally let the escape wheel run dry for that said 15 minutes when there's no cap jewel.
    • Sometimes there's a certain place under the bezel where the case knife is supposed to be placed. In this borrowed pic there's a small crack at 3 o'clock. 
    • Hi my fellow forum addicts, I'm writing this as I seem to have a hole in my knowledge (probably one of many!) I seem to have a horrible time removing bezels from watches. I am talking about the rotating type on sports/diving watches. I see many videos where the guy on screen barely inserts the case knife under the bezel and with no effort it pops off easily, then at the end it clicks back into place by hand with no effort. I am sure that part of this is due to skillful video editing, but I seem to wrestle with them, I have tried case knives and  even when using the tool below, I tighten it up in several positions and nothing happens. On a many occasions I have even warped the bezel in my attempts to remove it. Similarly, I have issues replacing bezels after cleaning etc. and often they have to be replaced using a press tool and inevitably are far too tight and will not rotate or loose to the point where they fall off or loose their click (perhaps due to micro warping when I tried to remove??). It is now to the point where I am actually avoiding watches with bezels as my success rate with them is terrible......please help!! In short I am asking: What am I doing wrong? What is the best method for removing bezels - how do you do it? What is the best method for replacing bezels - how do you do it? Any tips or tricks? Thanks
