I was torn between 3 watches....the AP 15300 (cousin to the 5711 by the original designer), the 5711 1a and the 5167 1a.
My decission was based on availability, or rather, the lack of availability.
No secret that the 5711 will get more votes from the "people". But, when you want all....what do you do?
In the last month 5711's started showing up the the dealers. Within 2 weeks there were vertually gone. I believe I got the last one available during this distribution run in the SE Asian region. I jumped on it because it might have been a year before I'd get another chance (for a new watch on this side of the world). I knew at this time the 5167's are in the windows of the AD's and moving at a 'normal' pace...the 5711 doesn't even make it to the window. The AP 15300, also, is not difficult to get these days.
I would have to admit, that if all three watches were easy to find, I would still be torn as to which direction to go.
If I was you and could get a 5711....go that route and get the other later...the 5167 should be available for a few years (I say that with no real substance of knowledge, as PP tends to do some funny thing with some models).
OH.....but it is fun making these type of decisions.....now back to work, making the less fun decisions of everyday.
