Message for ‘Francesco’ about his 7803 Cosmotron

I had an enquiry from ‘Francesco’ via the enquiry form about his cosmotron. Unfortunately my reply is coming back as ‘undeliverable’, maybe because his inbox is full 😦

Hopefully Francesco will see this – and here is the reply I tried to send via email:

‘Hi Francesco, thanks for visiting my blog. I am not a watchmaker myself so I only have limited technical knowledge. With monobloc cases you have to remove the bezel and crystal, and there should be a lever that can be moved to release the stem so the movement can be removed from the case. Here’s a forum thread that will help:  You need to scroll down a bit to find a pic of the dial side showing the lever. And the original poster says that the lever is pressed down to remove the stem. Hope you can sort out the problem’
