Which PO movement?

Recommended Posts

I have a dilemma on which PO to buy:

I am looking for the version with orange numbers (see below), but a Miyota 9015 version does not seem to be available.

 

Question 1 - Can anyone tell me if there is a 9015 version with orange numbers out there?

 

The BP version seems to be 43.5mm, whereas the Noob is 42mm, as the gen. In this thread from 2014 BP and Noob are compared side-by-side, although back then BP used a reclaimed 2836 movement instead of a Miyota 9015. From the thread it becomes quite clear that Noobs is more accurate in the details than BP.

 

Question 2 - Does anyone know of a more recent BP vs Noob PO comparison? Via the search I couldn't find any. I would like to know if since 2014, BP became more accurate (as they have also "upgraded" from most probably A2836 to Miyota 9015.

 

A friend of mine bought a fairly expensive watch for $700 (unknown brand but from the build and store it was sold, it's an ok watch, probably Citizen-range). I was surprised to see that this watch runs a Miyota 9015 movement. That gave me comfort, as my fear is that the rep I buy will quit on me within a year.

 

Question 3 - Is it fair to say that a Miyota 9015 is more reliable than a A2824 because the latter is made in perhaps dirty factories in China whereas the Miyota comes from a more high-quality (legal) factory in Japan?

 

Question 4 - If TDs list a watch as having a Miyota 9015 / GEN Swiss ETA 2826, is this the same movement as the one in my friends watch (with Miyota 9015 engraved into the rotor) or will it be a Chinese version?

 

In conclusion: based on my many readings on this forum (thanks everyone for contributing!) I would prefer the Noob over BP because it is available in orange and because it seems to be the more accurate rep. However, the Miyota 9015 seems to be the more trustworthy movement, although a more noisy rotor the A2824. So now I am in doubt on which version to buy.

 

Any input would therefore be highly appreciated!

I'd buy the noob and keep my expectations low. I've had great luck with the Asian movements. Over time they've been proven to be as reliable as the other movements offered at higher prices. Remember, you're buying an illegal product from China. You have little to no recourse when/if things go bad.

The $60-$70 difference for a perceived better movement usually results in disappointment.

Good luck getting a GEN ETA. Repaired and cobbled together is more like it.

I don't doubt whatsoever this claim about "gen" ETA's (plenty of evidence) but what I want to know is where the bloody hell the chinese find so many old broken ETA's to hobble them together

I'd get the A2836. Mine have all been as solid and accurate (timekeeping) as their Swiss cousins. Only negitive I can offer is the rotor tends to be a bit louder.

My v6f miyota is absolutely dreamy. Some rotor noise but it looks amazing and has been one of my most accurate watches. One of my best rep. Got it m2m for less than $200.

About rotor noise: apologies for the noob question, but the rotor is the half-circle which is rotating when moving your wrist, thereby energizing the watch, correct? If so, how is it "noisy". I'm reading about "rotor noise" but have no concept of it. Does it move less smoothly when turning?

 

Secondly, what does m2m mean?

A louder rotor is usually what is said about the Miyota, not the A2826. Do you have any comparison?

M2M is member to member. Now that you have 5 posts you should be able to see it. Read the rules in it and you'll be fine :)

 

Rotor noise: yes, the rotor or counterweight is what an automatic watch use to recharge itself.

Movements like Miyotas, 775x (7750, 7751, 7753...), and the basic "21j" (where J means jewels) have the rotor charging the movement only in one sense of its rotation. Other movements like ETA (and relative clones) 2824, 2834, 2836, 2892, the Seiko ones and others instead have the rotor charging the movement in both rotation sense.

This means that for the first group of movements the rotor is fully free to rotate in the non-charging sense.

This can produce a bit of noise generated by the rotor central ball bearing. So the noise is the spinning of the central ball bearing, and can be easily silenced of at least 50% by simply putting the right amount (so a MINIMAL ultra micro drop) of oil (like the Moebius HP1300) in that bearing.

 

That also explain why the 2836/2824 etc aren't noisy: charging in both sense makes the rotor never free to spin.
