PT5000 Movement Reliability Over The NH35? - Watch Repair Talk

Hey guys. I'm new here. My name is Waris. I'm from Kenya.

Just wanted advice between 2 watches that im about to purchase from aliexpress. I can only purchase one of these. Both have similar or equal build quality but different movements.  The watch from the Cronos brand having a PT5000 movement and the watch from San Martin having the NH35 movement

Both of them homages to the Rolex submariner. Each to their own, but i have no problem with homages and as a person who can justify spending up to a maximum of $200US per watch, the notion of "save to get the real thing" doesn't really apply to me with all due respect to all the readers out there.

Now being a person on such a budget of watches, ideally i wouldn't want to spend money re-buying/servicing a movement in 5 years time. I personally want my automatic watches to last at least 10 years if not more without a service and be robust and reliable (for the above mentioned reason).

I am aware that the NH35 can perform this very function for me hence i was just about to pull the trigger on the upcoming 11.11 sale for the San Martin (anyone that doubts the ability of this movement for my criteria, please input your feedback) BUT the cronos brand have come up with something very similar and with the PT5000 movement available for $199 on 11.11.

Bearing that in mind mates, kindly advise on which one to go for. Is the PT5000 reliable and robust as the NH35? will it get me through at least 10 years of service without needing a refresh? Or should i just go with the trusted movement on this one? I don't really mind going for the lower beat rate of the nh35 so that doesn't really matter to me

 

PT5000 from what i know is a clone of the ETA2824 movement, 28,800BPH and to quote, "HKPT brought their highest grade of PT5000 to Glashutte in Germany to have it's accuracy reviewed by the Chronometer Observatory (They couldn't get this done at COSC; the worlds best-known accuracy certificate system, as they only test Swiss movements). According to the China Horologe Association, the standard set by the Chronometer Observatory at Glashutte is the world's most rigid. The observatory has seven testing categories, and only allows a mechanical watch a deviation ranging from minus 3.8 seconds to plus 5.8 seconds within a day. This movement then went on to be China's first-ever watch movement to reach chronometer certification"
