Can Date Movement Be Modified To Non-date

Recommended Posts

Question for watch makers, etc.

Can a ETA movement that is used in a non date rep. ie, Explorer I, non-date Sub, etc be modified to remove the date change mechanism? I would like my EX1 to not have date change engage when you pull crown. Only one stop and hack. What parts would be needed to change?

thanks.

All you have to do is remove all the datewheel parts...

As above, remove the datewheel and all the gears for it...

Rob,

i think he means he wants to still have the datewheel but not the quickset function (at least that is how i read it , lol) , like a 1570 movment basically

thanks guys!

I did try that, but still get two positions when I pull the stem. would like it just to pull to one position and hack. Maybe i'm missing something.

The stem would have to be changed. The indents (what that little push pin releases from when removing the stem) sets in the spacing of the stem itself. You would have to get a stem from an ETA non-date caliber of the same series or file down the ident position you want to eliminate and your problem would be solved........I think.

I mean, I did stay at a Holiday Inn last night so I've got that going for me....

Removing the calendar gears has nothing at all to do with the keyless works. Expecting the stem to suddenly have 2 positions, when you did not replace any keyless works parts, is impossible.

A quick review of how the keyless works operates, what part makes the stem set in 3 positons, and reviewing the ETA data sheet for the 2801-2 series will give you the answer you need, and the part you need to replace.

ETA site is here...https://secure.eta.ch/CSP/DesktopDefault.aspx?tabindex=3&tabid=28

Have a look, it will be readily apparent.

Thanks Rob, unfortunately not registered with the site, so I can't view the link... unless it is because I'm using Safari on a Mac... keep getting an error page. Sent an email to Eta enquiring about registering. Cheers.

I am not registered either, but I can get in and look at the docs...must be a firewall problem...

ETA will never let you register, I tried many times, they are tighter than the military on who they let in...

I have the doc in PDF if you have a way to get it from me.

The part you need is 445/2 ETA 2801-2 this part should make the stem work in 2 positions vs 3.

Cool... got it. That is the part that needs replacing! I'm sure this will work for 2824 and 2834. My brother's Mil Sub could use the update as well.

I'm also looking at updating a movement to 2892, so I guess the correct part would be 445/ 2890, as the 2890-2 was the non date version of the 2892-2.

thanks for pointing me in the right direction.

445/2 is the correct part number.

I am not familiar with the 2890, but it's the same idea on these models, the part functions the same on both of these models, meaning it's got the notches in it for the detents on the set lever...

If your ordering from Ofrei, for gods sake, dont' mess up the part number, or good ole Bob will have to call you and scole you in person (he did it to me, and many others... which is why I do my business elsewhere now...).

That is too funny! I called them, and gave them the part number, but they said they didn't need it! Huh???? They said they just needed calibre and part name and they could look it up from there. I gave them part number anyway and they said they wish more people would use part numbers. I did get scolded for calling a part something different then what they call it. I asked for a Second Wheel Pinion, which is listed on ETA parts chart, and the guy on the phone freaked and said it was the Fourth Wheel. Oh well. Maybe I'll try JulesBorel next time I need something.

I stay away from Ofrei and don't recommend him to anyone...they simply like to make everyone's life miserable...They will scold you at every chance they get, and in my experience, they overcharge for shipping. Charge $14.40 and it's postmarked $5 or less...

Every chance I get, I tell people to go somewhere other than Ofrei.
