Swiss 2002Tii

I used two small screwdrivers, one in each hand and spun the locking rings CCW.  The tabs on the plastic bezels can be fragile, but the ring iitself is pretty strong.  Be careful pushing the rings out to avoid breaking the tabs.

I recommend that you mark each steel locking ring and bezel to keep them paired.  I had some difficulty getting the locking rings to seat properly because I didn't do this.

And don't use paper towels to clean your glass!  Soft cloth only!

Thanks! Took a bit but finally got them apart!

I had difficulty getting the rings to "bite" into the bezel enough for them to seat and hold the glass without rattling.  My solution was to take an X-acto knife and carefully slice the bezel along the cut line so that the ring would bite further into the bezel.  A tiny bit of silicon grease on the edge of the three steel ring "teeth" makes it slip more easily, but be careful to keep the glass clean!  Nothing more aggravating than getting it all locked together and realize there's a smudge inside the glass after you mount the instruments!
