: They both looking great. I especially like the 1153S. We see so
: many of these (S and N) in all sorts of combinations - various
: styles of wider hands, double batton hour markers etc. This one
: is what I call pure - single batton hour markers, thin steel
: hands with black inset matching the markers, tachy at 3 and the
: 3,6,9,12 hour register.

Agreed Paul, but I think only a handful of the combinations were as the designers intended, the rest is being pragmatic and using up the parts! This one is just as you'd expect it to be with a 149xxx serial - the same dial furniture as a Chronomatic, only with an "Automatic Chronograph" dial. The second execution hands start appearing not long afterwards ex-factory.
