    Is the C better than the earlier once?

    Yep. There were some issues with 2500A and B that were fixed with C.

    Thanks. I'm impressed of the accuracy. This is my first Omega and It runs better than any other watch I have. [​IMG]

    And the issues with the C were eliminated with the D.

    What were the issues in C? Are they under Omega warranty?

    The movement would cease to run. Something about the lubrication used on the jewels of the escapement.

    Depends on how long the warranty was and how old the watch is. I'd imagine most are not covered anymore.

    My watch is 2009 and runs well. I was just thinking if it's manufacture defect, shouldn't they fix it for free..

    The issue is a poor design really. On all the 2 level co-axial watches, the intermediate escape wheel and co-axial wheel have teeth on them designed to be part of the escapement action, and also be power transmission teeth. This requires an unconventional tooth shape, and this lead to a build up of sticky black residue on these teeth, as shown here on this 2500 intermediate escape wheel:

    There is a work around, but time will tell if it's a true solution to this problem. Omega certainly thought it was better to make all their current watches the 3 level co-axial design, which eliminates the problem entirely.

    In terms of warranty, there was no extension of warranties that I am aware of because of these problems.

    Cheers, Al

    Thanks for the info. Does anyone know the lift angle of this movement?

    38 degrees, but to accurately measure the balance amplitude on any Omega co-axial watch (or the Robin style Audemars escapement) your timing machine must have specific programs for these escapements in the software. If the machine you use does not have these additional programs, then the balance amplitude readings will not be reliable. These programs are, to the best of my knowledge, only found on very high end machines costing many thousands.

    Your machine is not one of those having the proper software.
