eta (swatch irony)

[watchweasol]

Swatch irony movement ,  This movement is one of the plastic un repairable units the only identifying marks

     are 1R25 pressed into the battery hatch base and V81R23  stamped on the plastic. Looking at all the data

    on the ETA sites would lead me to think that this one of the fasionline units 11 1/2 ligne  the replacement unit 

   being the 805-122   11 1/2 ligne day/date as all the dimensions seem to fit, all that is except the origional unit

   and the dodgy numbers I have been unable to trace.  can any one shed any light ? thanks Guys

If it's a Swatch Irony then they made many different models! You only have to put the keyword 'irony' in the Swatch Watch Finder (https://www.swatch.com/en_us/watches/) to note there are 1922 matches!  An educated guess is therefore that it's not '1R' in your numbers but 'IR' for Irony (?) and the numbers are then an internal code simply to ensure a tie up to a particular model. Maybe.

Thanks watchmaker   you are probably right, when searching the swatch/eta sites the model range was large , as they are designed as disposable  watches or in swatch speak not dismountable as  its made from synthetic plastic heat welded in and not easily to undo,  but being of the curious kind I made the attempt and opened it up and had a look. Its now on one side  as a do later job. I managed to get it running for a short while.
