It's a Autavia GMT. Does anybody know how to pop off the back? Want to check out the movement. I know it's a snap on back but it looks like very heavy construction. Not sure if I can do it myself so before I end up scratching up the case back I thought I'd ask first. I'll post pics later tonight. Thanks!

Regards,
Chris

P.S. Thanks Chuck! I missed the one on the bay. Went out for dinner and forgot to place a bid :-(
