My Seiko 7016-8001


Recommended Posts

Well the watch repairer has opened my watch up and taken a couple of phots and sent them to me.

It is a bit of a mess inside as well as a couple of missing C clips. One that is on the main bridge. I wonder where it went?

Anyway, gave them the go ahead to clean it all up, and fix what is needed. Now I just need to see if I can find an original band? I'll be much more careful of it now.

First one is rust. Like I need to tell you guys. Second is a photo of the rotor bearing which is shot as well as an arrow pointing to the missing C clip.

Got another email from the watchmaker that is servicing my Seiko.

It is keeping pretty good time he said.

When he was going over the case, the start/stop pusher tube into the case has been replaced with something that is not the same as the reset pusher.

Apparently, Seiko never made the tube as a spare part and you had to buy a new case. Seems odd as it would be a separate piece. Why a pusher would not have come with one seems odd. Hey, what do I know?

Anyway, Matt is going to look at making one if he can't get his hands on one. The one on the right of the picture is the dodgy one. The state of the case around it is not lost on me either. Grrr. Looks like it was hammered in from Darwin.

Hopefully, Matt can tidy it up a bit.

An idea to consider:

Generic pushers. They are made for Rolex/Tudor and may only require taping the case to insert. 
 

I have seen generic for Omega as well, though not replaced them, and those may be press in rather than thread in. 
 

But the Rolex (and later Omega) have the knurled lock ring; early Omega are plain, which yours would have been. Might be worth looking into for a more solid repair.

Lots of parts which are in fact separate are not sold individually. Other examples are  the rotating bezel insert, or the mainspring. The latter fact is guaranteed to give an hissy fit to beginners especially. Normally that happens when special techniques or tools are needed, and chances of damage are significant

In the end it simplifies the maker but increases repair cost, unless the repairman is able and willing to go the extra mile.

The practice is not certainly not unique to Seiko, or for that matter, to the watch industry.

I would like some opinions please.

As you all know, I have my watch back and am pretty happy with it. One thing that I did say to them in a letter which accompanied the watch was that the day wheel would 'stall' if you progressed the day wheel via depressing the crown. This still occurs. The only thing I am disappointed with. The day progression occurs completely ok if it occurs by the time advancing after midnight.

Now here is my logic.

As this only occurs when advancing the day wheel via the crown, the issue is with the crown depression to the day wheel. I don't know if the same mechanisms are used for advancing the day wheel via the hands rotation? If a different mechanism is used between the crown and the normal operation AND it only happens in one place (THU to IIII) on the day wheel, the issue has to lie with the day wheel.

Where I run into a logic problem though is that there can't be two different sets of teeth on the day wheel to advance it and since it works properly with normal hands rotation, that points to the mechanism from the CROWN to the day wheel. However if that is the case, why doesn't it happen on other 'manual' advances of the day wheel?

Am I missing something?

No. You need to take it apart, at least partially, to understand the calendar works, and find why the defect happens.

The video below by our Host should help you understand what you would be dealing with, being the calendar design the same or almost.

    • 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.
