Dates Do Not Change Smoothly Between 25 And 30 Of Each Month (Asian 2836)


Recommended Posts

Hi folks and pros

I have an Asian 2836 movement watch and recently the below mentioned issue surfaces.

The watch is working perfectly. But when I rotate the Crown on date set position, the date changes well, except between the 25 and 30.

During these dates, I need to rotate the Crown anti clockwise and close wise a few times for the date to change.

It does not seem to me that the date wheel is rubbing on anything and I suspect that it is one of the following :

1) the gear teeth on the date wheel is spoilt between the 25 and 30?

2) more lubrication is needed on the date skipping double?

Kindly advise please.

Thanks

More things to come.

You will need to strip the dial side to see what the issue is. If it is always between specific dates it might be damage to the date ring teeth at the area. But the strip down is the only way to investigate & fix.

Could be a bit of grit stuck under the calendar ring or could be a dodgy calendar ring but you know where to look.

If you can't see anything obvious then slightly loosen the screws of the retaining clamps and see if that fixes it. If it does then you need to see why (is the calendar disk warped? Is one of the teeth bent? Is the groove under any of the clamps poorly finished?)

I am working on 2836 as well. Is there a video that shows how the calendar/day rings work? I tried to 'work' the date change without the rings but, since there was nothing there to change...

 

I'm thinking a video with transparent rings might be able to show how it works.

 

I'm always amazed how all those small parts work together and that there is nothing there that shouldn't be there; no room anyway.

    • in general this shouldn't be any change. but in general questions like this it be nice to know the specifics of the watch in other words how was it performing before it was cased up and what is it doing now.
    • just as a reminder this watch is a Swatch group product. This will bring up a problem like spare parts and technical information. that I found some links to some information on when I talk about your watch and some of the technical and basically your watch is equivalent to 2834-2 for which I'm attaching the technical sheets. But equivalent does not mean exactly the same you want to do a search on the group for C07 as we discussed this watch before including the technical differences how it's supposed to be regulated and basically because it's watch group there is no parts availability. https://calibercorner.com/eta-caliber-c07-xxx/   https://www.chrono24.com/magazine/eta-movements-from-the-2824-2-to-the-powermatic-80-p_80840/ https://www.watchuseek.com/threads/h-10-movement-details.4636991/ eta CT_2834-2_FDE_481857_15.pdf
    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
