as i was just replying, i realised bro hobbit replied too.
i agree with hobbit as in there's no need to go for a 47mm yet as those really are for the big guys.
as for asian wrist, as long as u have a bigger wrist than 6.1", most likely u can wear a 44mm luminor or a 45mm radiomir.
also another advise, earlier on a bro asked us about the same thing and i advised him against a 40mm.
he went ahead for a 40mm gmt and regretted just a few weeks after and traded for a 44mm base marina in the end.
reason being simple, u r after a panerai becos of .... ?
u should find that out first.
for me the allure is simple:
(1) big watch 44mm wears nicely on my 6.3" wrist
(2) good name, good history
(3) clean dial (i'm a base nut) - rarely i see clean dials with NOTHING, look so nice
(4) good resale value
as for (4) i do understand many people disagree with this as they say "i'm buying to keep forever".
well, it's different for me, to a certain extent i know i will not be keeping it forever and i will want to change or swap once every couple of months/years/whenever, so i'd like the option of selling it easily (and of cos, holding good value ~80%+?)
so far, my experience tells me, the luminor 44mm answer all those above. some radiomir 45mm fits in also.
my advise is to go find a dealer (AD or grey), and try on the base models.
only then will u know if it'll fit u.
btw, i see girls with small wrist wearing 44mm lately. it's crazy but i like it
