SMP Chrono x 100
I've been wanting a good replica of this watch for like 5 years now, and have even owned 2 genuine chronos. Beautiful watches, timeless, and the rep is accurate as hell. Few minor issues but overall it's outstanding.
On the otherhand, the PO chrono has quite a few more innaccuracies. Though if it's inconsideration in the first place, you're obviously not looking for the more accurate watch. In the end go for whatever grabs you more, for me it's hands down the SMP chrono.
