This is definitely something worth replicating. I know the gen has technology that repmakers don't have, yet (i.e.: U Boat steel, drying capsule, etc.) but it's worth trying.
I can vouch that this watch is very very legible under various lighting condition, true to its label of Einsatzzeitmesser (mission timer).
Plus, after half a day wearing it, this watch is very comfortable, much like wearing many IWC watches.
