Does the 2500c movement suck, or is it all overblown?

[ralpie]

I see a lot of sellers posting that their Omega Planet Oceans have the 2500D movement and not the dreaded 2500C movement. I know that the 2500C is accurate because I was able to tell that from searching around here.

My question is about durability. Is it just a vocal ~.05% failure rate or is it more like 10% failure rate on the 2500C movement?

How much would it cost to fix a failed 2500C assuming the warranty expired?

Thanks!

I've owned seven cal 2500C movements over nine years including "A", "B", and "C" versions without one glitch. And all were as accurate, if not more so, as the three cal 8500 watches I have owned.

My watchmaker is Omega trained on the 2500 and says the reported "stopping" problem is usually caused by over-lubing of the movement. Normal service is all that is usually required although Omega also recommends replacement of an escapement wheel.

Thanks Fr. John. Looking forward to purchasing my first 2500 watch. Wanted to hear from you guys first to make sure it is reliable.

Does Omega allow warranty transfers?

I prefer the 2500D, simply because it's the "latest and greatest" version of the movement from Omega. With that being said, I wouldn't hesitate to buy a 2500C powered watch. I think the "issues" associated with the movement are due to keybangers being more vocal when something goes wrong.

Yes, they are transferable, Omega warranties are like automobile warranties and follow the watch, not the purchaser.

The 2500C was a reliable movement, the problems were with the earlier A and B variants. The C uses a two level Co-Axial escapement, whilst the D uses the optimum three level escapement. A very small problem can sound like a huge one with the internet, I would take such reports with a pinch of salt. Standard service price for an automatic Omega (Co-Ax or not) over here is c. £300

There is no proven performance difference between the two movements. I think what happened was new owners that did not know much about the movements decided putting C or D thinking that there was a significant reason to do so. The Planet Ocean started with the C 2500 movement and ended with the D. There has been a lot of speculation about this minor change some believe it was for simplifying internal manufacturing purposes.
It has mushroomed into just hype that some owners like to say.

I owned a smpo 45.5 and it embarassed all my Rolexs in terms of accuracy. EMBARASSED.

[Mystro]

Yup, the movement is legendary super accurate. I think mine was the king of automatic accuracy with a forum documented 42 days at +or- 0 seconds... It was better than any of my quartz. I got tired documenting it's accuracy every day and gave up at 42 days.

The balance wheel on a watch travels the equivalant of going from the Earth to the Moon in 50 years. Considering that, a 2500 may only be serviced 7 or 8 times. Not too shabby...

I think they're going to stand the test of time.

Wow that is very impressive.

I have a 2500c and as of over 2 months of checking the accuracy ( have had the watch for longer ) I have not lost even 1 second ( after experimenting with different resting positions ). That,s 2 months and accurate to the second.

I can't vouch for reliability as I have only been an Omega owner recently but of the 3 2500 watches I have had (2 x 2500C, 1 x 2500D), all of them are highly accurate. Within +1-2 secs/day.

The change was from a two-level Co-Axial escapement to the optimised three- level Co-Axial escapement as you would find in the cal. 8500. This is more complex than the escapement found in the 2500C, but is more efficient

nothing is overblown. the 2500D has the 3 level v.s the 2 level on the C variant as GMT master said. sellers of course will want to distinguish this and buyers have a right to know what variant they are indeed buying. justified or not, like it or not the 2500D is simply more desirable ESPECIALLY in the old version of the PO because it it has since been discontinued and the 2500D had around a 8 month run in the POs ** all other POs did not have the D variant. VERY limited. As of right now the 2500D is only used in the latest seamaster 300m.

Out of all my watches my 2500 is the most accurate. So far not an issue. My wife has the 8520 caliber and it had to be sent back to Omega HQ to fix a problem with the rotor "catching" when manually winding - after a few months of ownership.

Never had an issue with reliability in two years of flawless ownership.
