You can ask friendly before. I always recommend in Europe: www.rio-uhren.de

I’ve got to say that I think it’s belittling peoples experiences here to basically say “this is what you should expect with independent watchmakers”.
In my experience, using 5-7 different watchmakers over the last 12+ years, although comms are occasionally missed and deadlines slip, it is generally no where near what people are describing here.

I’m not sure I’d call waiting 2.5 years to find out he can’t repair it a positive story.

Based on this picture of the movement, AI has the following to say… let’s see how right it is!

🔍 Key Observations from Your Image:

1. The chronograph heart cam is missing:
   • The central chronograph seconds wheel is present, but I can’t see the heart-shaped cam that allows the reset hammer to push the hand back to zero.
   • This would explain why the chronograph doesn’t reset properly - the reset hammer has nothing to act against.
2. The minute recorder jumper/spring looks absent or displaced:
   • The minute recorder mechanism (which counts minutes when the chrono runs) may be missing its tensioning spring or jumper.
   • This would prevent the minute subdial from advancing correctly even if the seconds hand worked.
3. The operating lever and/or intermediate clutch may be missing or misaligned:
   • The key levers that control start/stop/reset aren’t all clearly visible. It’s possible one or more are missing or installed incorrectly.
   • Specifically, the horizontal clutch or intermediate wheel connecting the chronograph to the train might not be in place - preventing transmission of movement to the chrono hand.
4. The column wheel is present:
   • That’s good - it’s the tall, gear-like component just to the upper right of the center. This part governs the coordination of chrono functions via levers.
   • It appears intact, but we’d want to ensure it rotates when the pusher is pressed.

🛠️ What to Do Next:

1. Get a parts diagram for the Omega Cal. 33.3 / Lemania 15CH
   These diagrams help identify each individual part, and compare to your movement.
2. Get the movement to a chronograph specialist
   A true vintage chronograph restorer can:
   • Confirm exactly what’s missing
   • Possibly fabricate or source rare parts from donor movements
   • Properly align and test the entire column wheel and hammer system
3. Source a donor movement (Lemania 15CH or 15TL)
   These are mechanically similar and were used in other brands too - they can sometimes be found more affordably than Omega-marked version.
