Problem with A7750 chronograph

[Giammy]

I’ve bought a Daytona sold as “Swiss ETA”
I think moments it’s just an A7750
The hours subdial of chronograph starts on its own even when it is not started, what can it be?
May I repair it on my own opening the case and “adjusting” or “put back in place” some wheels?

One of the worst movements ever put in a Daytona is the 7750. You will have to find a watchmaker on here willing to take a look at it.

Yeah! It is very noisy and the watch “dance” on my wrist when balancer is charging… hope the A4130 on the superclone is not like this 7750

 

[Hor-Fan]

Sure! Go for it!

It isn't, trust me.

You'd be better off chalking up that one as landfill fodder and putting your money towards a Clean or BTF with the SA 4130 clone movement.

 

[Giammy]

Yeah, I’m waiting for a Daytona with dangdong 4130

Did you find a fix for that issue yet?

 

[Giammy]

Nope, probably is the stopper of the wheel mechanism of the chronometer

You located in EU? There's some good watchmakers here that can repair that damn thing.
I only had issues with those movements in my ones as well..
Chronograph didn't work all of a sudden.. Second hand runs wenn chrono activated yadayada..

As a side note, some of the older 7750 movements would encounter this issue. I had an old one from way back that would slowly wander. Mine was in a tag replica . Pressing the reset button with zero it out though, then it would randomly wander again sometimes later that day sometimes not for a week or so.

I have a sugess tona with a 7750
basically a low tier rep with a homage dial and crown.

I never use the chrono. It's wonky as hell. Reset button works when it feels like it.

Very comfortable watch though and nice when you don't want to wear a rep
