Which is better option? Both manual wind, no date, slim dress watches with display backs. Zenith 40mm whereas Nomos is 38mm but I would think both would wear similarly on wrist based on Nomos's lug size. Zenith is twice expensive but on gray market, you might get it cheaper than Nomos Orion or at least equal, so price isn't the issue.
Anyone know more info about their movements and their comparison? What about servicing costs? I know Nomos is pretty affordable in that area, no idea about Zenith.
