Thank you!

Your watch looks fully original. The case looks pristine, and the dial show the typical degradation of Omega dark blue dials used in seamaster 600 and 1000. By looking at the condition of the case I would assume this watch has never seen the water or even been used.
In order to open it you shall remove the bezel and then unscrew the threaded ring which lock the glass. In order to execute this you will need a suitable tool. I opened a couple of sm1000, it is not an hard task, but if you are not confident it would be better to make it done by an experienced watchmaker.

Thank you very much for your reply and advice.
I'll be writing again soon to let you all know how my research is progressing.

I don't know how practical these are for daily wear, but I hope to find out someday...

Just a quirky watch, but super-cool at the same time. Even non-watch people are going to notice THIS on your wrist.
