Hi there,

I have too little knowlege on those to comfortably dive into a deal.

there were the ones with the 2500 movement and later with the 8500 IIRC ...

how could you tell the difference? I also seem to recall something about different font-typo on the date-disk (or is that SMP only)?

also, I have seen different (main)crowns, it seems


thx for lending me a hand ...
cheers
Al

 

On mine you can look right through the display back and see 8500 clearly embossed/ painted on the movement.

 

Also the 8500 would probably be marked "Master Co-Axial" on the dial instead of just Co-Axial I think. Could be totally wrong on this though

EDIT: Yes, I was wrong.

 

jep, get a feeling its a (closed back) 2500 ticking in there ...

 

yes, it is a 2500. and an A, B or C as the D would have the 1 with tail rather than stick. Still a good watch without question and you have the advantage of a slimmer profile. that being said make sure it has been serviced recently or add service to your budget when buying. Also note the non ceramic bezel which is an advantage to me on this model. I like the retro look aluminum gives to the divers.

Also, as noted, the case back will be steel. Also a plus over the sapphire to my taste. It comes up to prize and wether you where hoping for a "latest" model or not. If you're not and you like it it IS a great watch.

 

That's a first generation, 2500 movement, PO. Yes you can tell what version you have by the date wheel, although I don't remember the different characteristics except that the 2500c has a 1 and not a I and the four is pointed or closed like this: 4.

I need to sell my PO to help fund the SM 300 I bought, but I haven't gotten motivated. I have found the 2500c PO to be as accurate the Master Co-Axial in the SM 300. The second generation 8500 movement PO's are too thick for my taste so I think the 2500's are keepers. I tempted to let my Dad wear my PO until my (almost 5 year old) graduates college.

 

The dial on the 8500 will have raised indicators at 6, 9 and 12 on the dial. Also the "Omega" branding. I ended up selling mine, the 2500 version is actually more comfortable to wear IMHO.

 

No

 

I spot by Bezel as they are different in the 12 hour triangle and the 8500's have the inner stripe on the bezel. As others have said the easiest way to ID is the back. The 8500 is a display back the 2500 is not. The 2500 watches have a slightly thinner case which combined with the non sapphire back makes the watch wear alot smaller for most people compared to the later 8500 movement watches. In fact I have a 3313 over the 9300 for this reason... I do also prefer the 3 subdials.

Double check that watch... the crown is either not screwed in, or the wrong size in the pics, The HE valve also appears to be different then my 3313 as having 2 different raised groove sizes which should be the same. It should also have slightly raised hour markers with a silver outline I cannot tell if they are in that pic they look flat. Of course it may just be the pics, but there are some high quality fakes out there.

 

thx you guys ROCK!

for any other people that might come along the same way, here's a (generic) pic of how the watch should look like in detail:

There are some very, very good fakes of this model. Make sure you Google search the serial number, and check the placement of the HeV valve around the 10 'o clock position. Hopefully you're buying in a secure fashion but as has been said, these are fantastic and wear even better than the 8500 series (these are NOT master co-ax at this point in time BTW).

 

a quick slam dunk way to tell the difference btween 2500 and 8500 is the open 6 and 9 on the 2500. (tiny gap between the curve and the main stem of the numeral.

 

So basically we are saying while they look identical from a few feet every part of this watch is different.

It's kinda funny how each of us has a different way to quickly ID them.

 

The C has the same characteristics as the A and B, what you describe is the D version which is the last iteration of the 2500 movement and the one you currently find in the smp 300.

 

The 8500 is about 2 inches thicker than the 2500.

 

2....milimiters?

 

I mean, if this is really about differences between the 8500 and 2500 then it's a very very very easy thing to see. I thought it was more about what 2500.

8500

Thicker...considerably so
Ceramic bezel v aluminum
Bezel is a dark grey dial is black ( the 2500 is the opposite)
Applied numerals
Applied logo
Closed 6
Saphire case back v steel

There's an exception with the liquid metal limited edition 2500 Cal which has ceramic. Black bezel and dial applied numerals and logo. Red instead of orange legends ceramic bezel I stead if aluminum steel case back etc...basically take the best of both watches into one.

And then there is what is coming this year which seems to be bringing back liquid metal into the equation and a slimmer case but at 43.5 instead of 42.... And the rest we will see.

 

The best of both worlds is to own both the PO 2500 Liquid Metal Limited Edition AND a Titanium PO 8500 Liquid Metal

 

This is indeed not correct. Though all Omega models in future 'll be fitted with the Master Coaxial movement the PO has until now not been fitted with this movement. I read this on the Omega website so it's straight from the horses mouth so to speak.
Regards.

 

The PO never came with an A or B, and will only have a C or D.

I would also caution against using the date indicator as the sole way of determining if the watch has a D rather than a C. I have had requests to swap date indicators out in these watches (top put a D indicator in a C movement) which I have declined, but that doesn't mean everyone will.
