Omega

Hi all, does anybody have one of the Omega models mentioned above with the calibre 3133? I tried to use the "search button" but without any response and - unless I went wrong in the search - wonder why just a few person consider to buy these watches, which are in my honest opinion the best Omega chronographs. For what is in my knowledge the calibre 3133 has a vertical clutch that allows the chronograph to run continually without any relevant problem, a free sprung balance and of course the intersting co-axial escapement. So...how many of you have one of these watches? What about their accuracy and reliability? Have you ever had problems with them or the just work fine? Thank you all for your answers

I dont have one of these in my collection.  But I will check to see if I know anyone who might have some first hand knowledge about them...

Best regards

3133 is a Poljot calibre and others might say it's a better investment than the Omega 33xx  and its derivatives.

I have a De Ville Chronograph with cal. 3313.   I think it works fine, although the first one I bought had a reset problem and was returned.  This example has been trouble free for just over three years.

It has a pleasant feel when actuating the pushers (light & crisp), no jumping when starting (like the Speedmaster Pro 186x).  Drawbacks are limited to an occasional wobble from the uni-directional winding mechanism and fear that one day the thing will crater with the problems that have been reported by some that buy these models.  Accuracy is very steady at +3 sec/day, with little positional variation.  It hacks, so it's easy to correct.

I can't eliminate the FUD factor, and here's my full disclosure:

(My Disclaimer: Excessive force on the reset pusher as well as simultaneous use of both pushers on a mechanical chronograph is a poor practice to the best of my knowledge.)

The Omega manual has the following special caution about calibres 3200, 3201, 3202, 3205, 3301, 3303, 3313, 3612, and 3603::

Note: never push the chronograph’s two pushers (A and B) simultaneously (calibres 3301, 3303 and 3313)

And to be fair, since the 3313 is based on the F Piguet 1285, I discovered the following:

In a 2004 Blancpain manual, regarding the (F Piguet) 1185 movement, it says "Do not press the button b [reset button] before having stopped the chronograph (button a)."

This wasn't in an older (undated, before 2000?) Blancpain manual I have. Of course, BP has to differentiate between the standard chronograph and the flyback version e.g. F185.

Not quite the same, but I wonder why BP added some extra instructions, too.

Dear Mike,
thank you for your answer, I found it very useful. I don't know why, but I'd have expected a better level of accuracy for a coaxial, but 3 sec/day is very good indeed.
