If you can afford, definitely the portuguese automatic. It is one of the most popular model that houses an in-house movement with the pellaton winding system. Alot of portuguese chrono owners out there "upgraded" to portuguese auto after some time. However, if you are an accuracy freak, the 50000s calibre is not for you. Portuguese chrono's accuracy wins hands down.
That said, its interesting that you consider a pilot as well along with the portuguese. The pilot and portuguese have totally different aesthetics with portuguese being more dressy.
Just my 2 cents.
To add on my views,
The portuguese automatic is thicker than the chrono.
Diameter is 1.1mm larger. But the Vis-a-vis increase in lug size and thickness also makes for a slightly more larger watch.
5000x series movement when viewed through the caseback is not really eye pleasing..movement looks unrefined.
Portuguese chrono got 2 variants, 1 pre mid- 2009 model, comes with stamped indices - this watch looks cheap.
The post mid 2009 model comes with applied indexes. The numbers looks thicker and watch is more luxurious
One thing i hate about the port chrono is the lack of deployment buckle, and the lack of date.
But the size is near perfect at 40.9mm imo. Wish they had reduced it down to 40mm thereabout. Watch is abit boring cos no sapphire caseback. Rotor abit over-active. Didnt test it for accuracy.
I like the fact that the AR coating doesnt scratch easily and the watch dial layout is neat.
Portuguese automatic, might be abit too thick for cuffs nowadays. No good for small wrists with its dial size because its a dress watch afterall. The watch should not draw attention from the wearer.
Watch layout is abit spacious
Didnt test the watch for accuracy. has deployment buckle but it isnt activated by a push clasp system.
I personally dont test automatic watches for accuracy since its not quartz.
Only checked to nearest minute.
