Hello airborneintell,
you can order the ARCHIMEDE Vintage
http://www.archimede-uhren.de/EN/Vintage.htmwith a domed sapphire crystal with A/R coating on both sides as a special manufacture. The additional costs are Eur 140.
We do not have wristshots of the Vintage but if you google for
'wristshot archimede'
you will find those with different ARCHIMEDE models using the 42mm case.
Best regards
Thomas
