TAG Heuer caliber 7 Movement

[kygan711]

I need some help and advice from Sifu's.
I got a tag heuer which I bought long time ago when I was clueless on watch.
Upon my research I found that this watch movement is called TAG Heuer caliber 7 which in Tag Heuer website say it's a in-house movement.
Some info also says it's an ETA.

I was wondering if any of you are knowledgeable on TaG Heuer watches ?
My watch model is Carrera 7 Twin Time (WV 2115 ).

Thanks and appreciate your kind advice.

Should be ETA 2893-2
A very reliable movement.

Thanks Cocas for your quick response.

On another question, I tried to do the back and forth movement on the automatic watch to get it moving again. It moved maybe 5-10 seconds then it stop. I was doing this for quick a long time and a few times and tried winding the crown when it start moving but it still move for 5-10 seconds.

Is this a tell tale sign that something is broken or  a full service is required ? I have never done a service on this watch before and it's almost 10 years old.

Thanks.

If you wear it daily for about 5 years , you should have got it serviced at least once.

It's been running for 10yrs non-stop. It have proven its movement is a durable and reliable workhorse !

But the dried up oil could have caused several parts malfunction. Better send it for full service now, and stop trying to wind it in anyway.
