Kindly share the Omega watch models that having the  Omega logo laser inscription onto sapphire / mineral crystal glass.

Just like how Rolex does it at the watch 6 o'clock position.

Thanks.

All Omega watches with hesalite (Speedmaster/ Railmaster 60th anniversary) would have a logo on the center of the crystal.
Not with laser inscription though.

Oh I see. No wonder I saw a reversed U on the center crystal, at first I keep rubbing it with cloth and even using eraser to rub but failed.

Then I saw its zoom photo and realized that it's a Omega logo.

Omega doing this on hesalite crystal model since 70's. Wow! More earlier than Rolex?!?
