Extract from archives & omega watchmakers in Australia

Hello everyone.

May I firstly say thank you to those who replied to my first post regarding my 3582.50 speedy.

This is my second post and I seek any advice on attaining an extract from the Omega archives + does anyone know a quality watchmaker in Australia who specialises in Speedmasters?

I have (what I believe to be a 1989) a 3592.50 with display back. I noticed some Speedmasters have a number stamped on the back of the case - along the lug. Is this the case number?

My piece does not have a number stamped on the back of the 7 o’clock lug and only has a number stamped on the movement. So do I simply quote the movement number and send pictures of my watch to Omega?

Lastly, does anyone know a quality watchmaker in Australia that specialises in Omega especially Speedmasters?

Thank you and any assistance would be appreciated.

I second Evitzee's recommendation. of Adam.
What do you need doing? Just a service, or restoration and case refinishing?
Why do you want an extract of archives? Just curiosity?

I have never serviced the watch and would like to know what year it was manufactured and so on.
Thanks for your replies.

Thanks JimInOz
