The skinny I posted earlier is on a 20mm lug Lemania. That is how they wore them, because as you mentioned, 18mm is not easy to find (and I don't think they made 20) ... and most watches I have seen with these vintage ones (all skinny) are 20mm lugs (but honestly I have not looked long and hard, and will most likely snap up whatever Forstner makes
).
