I'll await your comments on the condition, curious to see how many hours this one lasts.

Funny that they disparage a watch they just sold (the 'winking eye' 2nd ex. 3147N) in their description of this one: "Later the date would move to 9 o’clock at the expense of a running seconds sub-dial, which we think is unfortunate as the earlier example really stands out from the few chronographs that toyed with the idea of nicely integrating a date window on the dial." Maybe to justify the price? Though I realize this is an earlier model and was made for a shorter period of time. All this to say I like the 2nd ex. more.
