Hello,
Sharing another Grivolas 400 day clock. I think this is with Ph.Hauck movement and pendulum. There are both Hauck and Grivolas serial numbers on the movement and pendulum. Best regards
Gintaras

Good morning all

My friend Michel has a pendulum in bad condition. He will repair it.
Here are two pictures.
Pendule de Michel1.jpg Pendule de Michel2.JPG


I am looking for a very high definition photo of the "hat" in brass. This piece is missing. The picture I put is not good enough for my work.
Here is the picture of the "hat" that I'm looking for a lot better.
Maybe someone has this piece in his collection to help me?

Heartfelt thanks.

Hi all
Just returned from B’Ham watch&Clock fair and as I was told didn’t find anything I wanted, but I did pick up this gem.
Grivolas pendule 400 jours not seen one with 12 and 24 hours before.
I think it is 1908 but hopefully someone will verify.
Sorry forgot to add serial number A.8.535.3

Nice...a Grivolas is on my bucket list! Yes, the "8" of the serial number designates it was made in 1908. According to what has been documented, there were no clocks made in 1907 and your serial number appears to be low enough that might make it one of the earlier ones made in 1908. The serial numbers were sequential throughout the range of clocks. The meaning of the last digit has not been determined. As far as the design, the case and pendulum appear to be their standard items...cases and pendulums could get quite ornate. The 1910 catalog doesn't even show any dials with the 24 hour digits...it might have been an option...but I don't read French!

My friend has bought last time a "German" Grivolas. Probably JUF, Grivolas SN on the left side of the back plate (with asterisc). But the disc pendulum is very strange (for me). Could someone explain what for are the drillings? And the ring under the plate disc? See pictures.

The only reason I can see to modify a disk pendulum such as yours would be because the suspension spring needed was not available. Adding weight is more common that drilling holes, but I've encountered both methods. Usually not on the same pendulum however. In its original condition, your disk would have weighed about 400 grams, and would need a thicker spring to keep time.

Hi Eric,
So first someone drilled this holes to made the pendulum lighter, but next added this heavy ring? Really strange, but maybe you are right.

Pendulum without drillings would weight ca 450 gr, now it weights 433 gr. This "ring" it is a circular tube solded at the ends. Is it a "self made" compensation prototype? I don't understand this strange idea.

If you want help reading the catalog, you can send me scanner copies and I will translate with pleasure.

Here are some pictures of my Grivolas. Besides the movement and the disc, the case itself is also numbered with 64, on almost every part, such as doors, pilars and grondplate.

Hello all,

let I start wiht introducing myself. I am since the first of January retired and have now plenty of time for my hobbies. Those are R/C flying, making wooden toys and - since about a year - 400 day clocks, preferable with discs.

My son bought a Grivolas which I posted above and since that time, they do attrack very much. He had the opportunity to buy another one, which is this one. More foto´s will follow.
He has now the number A 8 771-5 and A 8 739 - 0. The same year of production and a number close to eachother is pure coincidence.

Hello All,

the same day my son bought his Grivolas, I bought one also, from a person who had 7 Grivolas, standing more or less forgotten, in a cabinet.
The top piece of marble is marked, carved into it, with the number R 61, the lower piece is hardly readable.
Furthermore, on the top plate of the disc, there is handcarve the sign of CG and the number 5 - 20
DSC07458.JPG DSC07464.JPG DSC07467.JPG DSC07468.JPG DSC07470.JPG DSC07471.JPG DSC07472.JPG DSC07485.JPG DSC07500.JPG DSC07501.JPG DSC07502.JPG DSC07503.JPG
IMG_9718.JPG IMG_9719.JPG IMG_9721.JPG IMG_9722.JPG

The bezel is only screwed (4 screws) at the top. I beleive that has to do with the construction, because the little statues are screwed onto a diagonal pice of brass, so it would have been hard to make there two more bezelmounts.

What strikes me furthermore, is the lay-out of the discs. The disc belonging to number A 8 771-5 is (far) more complicated than the other two.
In the disc of A8 739-0 there are some pieces of lead, screwed under the two brass curved pieces, the disc of 3767 has no lead in it.

There is a catalog in existence for Grivolas clocks. I don't have a copy so I don't know anything specific about your exact model. Aside from that, it's a fairly standard French made clock case with some extra embellishments added to it. The dial has the minutes numbered around the outer edge. Those were not as common. I have a few like that from other makers. I think it's kind of odd to have a Roman dial with Arabic numbers as well, but there are probably others out there.

Is there anything missing from the top?

Hope this helps.

In the 1910 Grivolas catalog, it's listed as No 250 Regulator Gilded Bronze. It mentions Louis XVI ornamentation and feet. The catalog picture doesn't show front wind as your does...but I suspect various movements/dials could be included with any given clock.

I see Eric was up earlier than I! As for the top, the catalog doesn't show anything on top. Also the catalog picture of the dial is Arabic numbers.

Found me another one which does not have that ornamentation. Like this type of case more. It seems every part of the case has a number stamped into it? In this case the number seems te be 37 or 31. The movement is stamped A.9-1944-0. Should that mean it was made in 1909? The top of the pendulem has some kind of elongation, I have no idea what that is or what kind of function that has.

Yes, that "9" indicates the year 1909. The A means that it is the Model A suspension bracket. The end digit 0 meaning (and other numbers) have not been determined.

Very nice looking clock! The "14" in the serial number indicates is was made in 1914. Given the next four digits, I would guess that it is somewhat near the end of production.

Hello Kurt.
Many thanks for the info. Yes You are right clock is in really good and original condition. Until which year did Claude Grivolas produce clocks?

A couple of weeks ago I was offered two onyx Grivolas.
This larger one looks like no 290 in the catalogue,
Serial no A6- 310 -1 and has the cut outs for pallet inspection.
The other A-6-349-4 doesn't have the cut outs even though it has a later number.

This one runs well and keeps good time .
I knew the onyx was damaged So decided to take the case apart to have a look .
I used acetone to dissolve the bond it only took two days.
It's a mess , it's looks like a previous owner prized the onyx off with a screwdriver but I suppose this can happen to a clock when it's been around for a 115 years !
I've trawled this forum for info and I must say I'm not feeling very confident so any advice would be welcome.
Also should I polish the case or leave it with its patina ?

I had a case with not quite this much damage and had good luck getting it repaired by a local marble installer/repair shop.
I contacted several shops before I found one that would consider the project.
They matched the colors perfectly and the lines disappeared where the cracks were.
The down side is it was quite expensive. More than I paid for the clock.
I looked for over a year to find matching onyx to no avail close yes but still a noticeable difference.
I like the brass polished but each person has an opinion as to rather or not this is the best way to proceed.
Good luck. The clock is worth the cost of restoration in my opinion.

It looks as though the ornamentation is gold-wash; I would not polish that , if that is the case. Like, JK, I would polish the brass, but it is a personal choice. I always wonder how the makers would want it to leave the factory. BTW, you are indeed fortunate to have not just one of these, but two. Congrats.

Thanks for the replies, the second one is not the same it is onyx but smaller.
That one has a couple of pieces that need repair and only works for a short time.
I will take your advice and polish the case and thanks for the tip on the ornamentation.
Cleaned the base onyx this morning and a lesson learned is if it looks bad it's actually worse.
Bits of resin appearing, sides crumbling ,fissures that look like cracks.
I hope I haven't bitten off more than I can chew.
