For me, owning both the 116520 which I think appearance-wise is similar to the 16520 except for the movement, the bracelet and the hour markers and the 116500,I would still go for the modern ceramic version for the improvements made on the bezel which also highlighted the modern look. The 40mm size is also perfect.
In-house movement automatic put the watch ahead of the Speedy IMHO. The 6263 doesn’t do it for me.
