Please take a look at the waterproof Grand Calatrava brothers(2 different type of seconds) 2508R and 2509A from the 1950s.Both were manufactured in 1955.
From the left: 2508R center second（Mov.27SC） and 2509A small second（Mov.12-400） The unique dagger index is attractive. In later years, dials with bar indexes were also available. This model has also nice indexes. It has the unique beauty of a 1950s steel ...
Wonderful duo!
I have a slight preference for the 2508, but both are very attractive. Best, Emmanuel
Two of my favorite 1950's Pateks
Very beautiful! I had a 2508 with that dial. Was a joy to wear. Look how beautiful the second hand is on the 2509. Little things (or not so little actually)like that and the quality of the dial making I think were better back then. I'm comparing time only...
Thanks for pointing out the
“dagger” index ! I prefer the one with sweeping seconds hand because the dial is “cleaner” IMO. Do they get equal wrist time ?😃
