My EL has a very slight purplish tint from an angle... don't know if it's AR or not.
Additionally, let me know what stem size crown works ... (and the address of your watchmaker who does it! )
The cyclops is currently very satisfactory, apparently there is a second cyclops embedded in the date window on the dial, I don't know if the addition of the good cyclops might not be overkill in this instance!
I have considered swapping the case as well. What's interesting is that ELs version has a very tall bezel, taller than the other 44mm cases i've seen on any model...
