Watch crown

[Santiago]

hi everyone, I have been given a Rotary watch with the model number GB03429/20 (14255) which does not have a stem or crown. It uses a Miyota O20 movement and I have a spare stem, but would anyone know where I could find out the correct crown size. And would this be a screw down crown,or is there anyway of finding out? 

All help ell much appreciated!

Rotary case parts don't show up on any of the usual material house sites. You could try calling the number on their page for service and materials

Stem: 065-441, Tap 10, chances are it's not a screwdown, unless there are threads on stem tube. Good luck!

Some case styles have a slight indentation to the size of the button. If there is no sign of it being a screw down than it's not. It's just common sense in fitting a button you don't want it to look big and ugly, but you don't want it to small so it looks ridicules and you don't want it sticking out to far or it will rub the persons wrist, it should fit nice and snug against the case and match the colour of the case or as near as possible.
