I'm looking for advice on building my own watch using an ETA 6498 or 6497 movement.

 

Is it a straight forward case of buying the bits on Ebay and assembling them or there any pitfalls to avoid.

 

What is the difference between the 6497 and 6498.

 

There is a 6498 on Ebay which looks a good deal but the seller says he has had it in his desk for a while and never got round to using it. He has also sold similar items previously so I'm a bit wary as it's only £90 BIN which seems cheap.

 

Sorry I don't know how to do a direct link but here is the item no.111900328604

 

 

The movement has no branding, just "Swiss'', is this ok.

 

Any advice on how to move forward would be welcome.

 

Thanks, Mike

Hi Mike,

 

First look under the balance wheel and you will see the ETA logo and movement number: that's your brand and model. Also, the seconds hand should be at 6 o'clock for an ETA 6498 and at 9 o'clock for an ETA 6497 (since those were originally pocket watch movements we are considering the wristwatch normal crown at 3 o'clock). Chinese clones are pretty much the same: clones! They are all at least fairly precise according to finish, version, use, etc.

 

Regarding the cases, if made for this movement they should not have any problems other than quality: some better than others. Make sure the selected dial is made for this movement and has the proper dimensions to fit the case. Also, some movements, to fit correctly in their cases need an extra ring that restrict play (called movement holder, this is most frequent on those ebay "Panerai" cases). In most cases, the rings might be missing or not supplied.

 

Most parts among the original 6498/97 and the 6498/97-1 versions including Unitas original, are interchangeable with some exceptions given by, version (notable balance bridge among others) and "orientation" (98 vs 97). The higher bit version -2 is "less" interchangeable parts wise.

 

Also, do a search in our forum to find out more about this movement and its builds. I believe we have a lot of "experience" shared in here.

 

Hope this works for you,

 

Cheers,

 

Bob

      @carlosdv there is a pdf with the operating instructions further up the thread. It looks to me that you put the crown in the right position for the relevant subdial, hold down the reset or start/stop and adjust with the crown.   Tom

      Hello Mediatech, yes the back can be opened with a case knife, it is not very hard to take off or put back on. I would also like to ask a question myself. In my case my Polaris is having issues adjusting the chronograph, the subdials do not seem to work. I place the crown in position 2 to try to adjust them and nothing happens, same thing in position 3 for both of them. Otherwise watch works fine, the main hand for the chronograph was adjusted and works well. I consulted an Omega dealer about a service and got quoted 650€, now my question is about the movement. I think the movement is based or is an ETA 251.262. It does not seem to be in production any more and was replaced by the ETA 251.264. Is there any chance a movement swap would be possible? What are your recommendations? Please keep in mind this watch would not be sold and I plan to keep it with me for a long time.

      I am new to watch restoration. So far i was repairing two watches seiko 7002 and seiko 6309.  I manage to dissasemble, clean all parts except balance wheel in isopropyl 99% and then assemble and lubricate with proper oil. My cleaning included clean of mainspring and in case of seiko 6309 replacing with new generic mainspring.  When i partially check once i setup the train bridge and move main barel i can see train wheel nicely move and escapement wheel is spinning freely. After i add palet fork and then put back balance wheel the movement doesnt start by itself. It always needs like a small pinch to it by tweezers. And then it runs. But i can feel that the main spring is already wound so it needs some power to run. When i check on timegrapher by changing the regulator i can get to +-10s/day amplitude of 260 and horible error beat of 6ms Watch runs maybe 8h and then stops. Where do i repeat my mistake? Without any feedback i dont know what do i do wrong so hoping somebody could point me to right direction.  Thank you  Tomas
