187 movement conversion to Swiss question

[COLDI]

Does anyone know if a swiss 7753 will work in a 187? Specifically if the hands are a straight swap or if the will have to be broched? Hoping they won't need to be since gen hands are probably impossible to get.

My understanding is that the swiss movement the date doesn't align well with the rep dial.

Natas78 did that a long Time ago, you should search his old posts!

It fits, though a slight misalignment of the date will be present. Also, the rep chrono hand will not fit in the shaft. There was a sale listed on RG some ages ago.

If the 187 rep has a modifed A7750, their will be a slight misalignment on the date, but if its A7753 it should be okay.
The main chrono hand will need some broaching wether its A7750 or A7753.
