I ordered the upgraded version of the 'Pepsi' PD-1662 recently after seeing it was updated with the new Seiko NH-34 GMT movement. The non-GMT *NH-35A* found in a lot of watches is a well-constructed workhorse of a moment, and the GMT variant on this architecture is definitely encouraging. I'm going to counter all the negative reviews and share that the one I received has been perfect right out of the box, kept flawless time on my winder for a week before I unwrapped and sized it, and has not lost or gained any significant amount of time in over 2 weeks of constant operation. The new style of lume on the hour markers and on the bezel is really pleasant, but it gives the watch an overall different look and feel than the old style 1662 with the Pearl GMT movement, which had different marker lume. Overall this upgraded version feel like a 'Maxi' style with improved visibility all around. Case and bracelet remain unchanged from the prior 1662 (which I also own). The GMT hand sets with a comforting, solid click, versus the 'loose' open-ended adjustment of the Pearl GMT movement. I'll continue to wear both of these watches in good faith, but as always, I trust the Seiko movement for long live moreso than the Chinese Pearl movement. That being said, all of the Pearl GMT movement-equipped watches I own have been running with no issues at all for over 2 years now. A lot of 'problems' people have are simply poor care or treatment of the watches I think. Buy with confidence.
