Can't find much online to tell me what I need to purchase online, to remove case back, what battery, lube? Can anyone point me in the right direction without having to send it off?

 

Is there really nobody on here at all that changes their own battery, Everyone has it done elsewhere?

 

Don’t be surprised at the reluctance of a lot of folks to answer such elementary questions as you have asked. You obviously have no clue about cell changes on expensive, quality watches! We wouldn’t be doing you a favour to encourage you to wreck your Omega. By the time you check the prices on what you need to do a proper, complete job, including a water resistance tester, you’ll be glad to have someone do it for you.

 

Local jeweller was lousy, battery change didn't even last the year, and can't post it to Omega and it's not that precious.
