Removal of Date Complication

[LiamB]

This might sound like an odd question, but would it be possible to remove the date function from an eta movement? I am working on a project watch I am designing and building and I can’t source myself a movement with the desired specs that doesn’t have a date function.

Short answer is yes. You can remove the components that make up the date complication, however, you can't remove the stem position. In other words, there will still be a second position when you pull the crown out where you would normally adjust the date, it just won't turn anything.

I presume ETA self winders, you can eliminate the date complication, since date train is independent on em, that however dose not reduce the height. Base calibers have no date.  

Dr ranfft  lists variants of all calibers.

Absolutely yes, as above though there'll still be the intermediate position but as you won't gain any extra space you could simply leave the calendar works in place and put the dial over the top of it.

Thanks for the answer, however Sellita has responded to me and they sell the movement without the date function! So it shouldn’t be a problem!

LiamB,

Not sure what project you're doing but sometimes watches without day/dates have different dimensions.

So if you are trying to fit a no-date movement in a watch case which previously held one with day/date you may find the stem hole in the case and movement do not line up. 

If you are in contact with Sellita they should be able to provide you with the dimensions and you can compare that with the movement you're replacing.

Good luck!
