Jim, very interesting clock. This one uses the identical inlaid mahogany case as illustrated no. 250 in the Jahresuhren-Fabrik 1910 400-Day catalog. This is the fifth such "crossover" model with an unusual case design that I've documented for Grivolas clocks, including two with JUF movements having the special Grivolas serial number on the left edge of the back plate. The others are No. 220 wall clock, No. 243 crystal regulator, No. 245 mahogany table model, and No. 251 inlaid mahogany table model. There are several other cases shared by both companies as well as by Kienzle and Hauck, some with common model numbers and some different.Here is an interesting one that just sold on Ebay. Go to Ebay search and use this number.
Les, will look forward to seeing the photos of your clock. I suspect the case could be original even though not illustrated in the 1910 Grivolas catalog. I have a wall model that has quite similar balustrade top and carvings, have seen photos of others in the same manner. Does it have a pendulum?Just bought this one on a whim, don't know yet if the case is original, will post more when I have the clock.
This is the item description from the auction catalogue (Gardiner Houlgate Lot 945, 25-2-2011), I haven't seen the clock, but assume from this it has. I paid bottom estimate for it, which I thought was too good to be true.Les, will look forward to seeing the photos of your clock.

Just caught enough daylight tonight to get reasonable photos. Here are the pictures of the latest Grivolas as promised.Les, will look forward to seeing the photos of your clock.

Corina, thanks very much for your inquiry and posting the photos of your clock. Your English is just fine, much better than my German! The main reason your clock is not shown in the 1910 catalog, is that the wood stand is actually a "temporary" stand that was used for regulation of the movement and pendulum at the Grivolas factory, then used for shipping the movement and pendulum to a third party who would place the movement in its permanent case. Sometimes these were evidently not completed and can be found even in their original shipping boxes.Hello and good morning to all..
i hope, i am right here. I am a owner of a Grivolas 400 jours pendule..but my clock dont work. i am really sad. may be somebody can help me.
at first..sorry because of my bad english..hope you can understand me.
My grivolas is a model : B.11-3234-5 and suspension spring is broken. i would like to replace but i dont know dimensions. i bought a reprint of the catalog from 1910 but my clock is not inside. Also missing is the hook end of the spring. can somebody help me to find these parts?
i will enclose some pics of my nice clock.
Corina, thanks very much for the excellent photos. This clock evidently was intended to be an advertising gift from the newspaper "Le Matin". More than likely it would have been mounted in a nice 4-Glass crystal regulator case before presentation, in this instance that didn't get completed.hello again and thank you so much for all the informations. But something i can not imagine..the stand was using for shipment/transportation...with this glasdome??...mh..could imagine many domes get broken. But my dome is perfekt.
really, you are right..the other clocks in catalog really beautiful in theire cases. the wooden stand is a little bit ugly..but unusual..and i like it.
Yes..its written on dial " offert par le yournal le matin" i think it was a gift..and i hope grivolas did not made 1000s of these gifts.
i will enclose some pics..
and..big thanks again to you..i am really happy and will contact M&P
Jim, thanks very much for posting! This is a very attractive clock case that I've not seen before but in my view no question it is typical of Grivolas cases both for the German movement versions and the round plate Grivolas movements.This was listed on evil bay but for sale in a local antique store. It is not perfect but a lovely example in my opinion. Gilding probably redone at some time in its life looks extremely shinny in photos but is actually not so garish.
It is approximately 15 inches tall x 8 inches wide x 7 inches deep.
Edge of plate 475 *
No numbers on pendulum but it surely looks correct and original.
Says Tiffany on dial, I am not aware that Grivolas supplied them. Certainly is a high end case. Clock 223 in the 1910 JUF is the twin but with an earlier pendulum.The listing says GRIVOLAS, which is probably correct. The case is certainly consistent with their clocks. The movement is JUF, but the suspension guard is the Grivolas style.
I believe they assembled and sold clocks with other German movements as well. The pictures don't show them but there should be other markings stamped into the edge of the back plate.
Roy and all, I can postively confirm this is what we call a "German Grivolas", with movement by Jahresuhren-Fabrik (JUF), a French case, and dial custom printed for Tiffany & Co. by Grivolas. The Grivolas serial number *2794 is stamped on the left edge of the movement back plate, and the impression can be seen if the photo of the plate is enlarged. Based on my data, this movement was made by JUF in late 1907 and the clock finished by Grivolas about mid-1908, one of the last ones made by them using German movements. The highest number documented to date is *2930, the lowest is 99*. Note that the asterisk here represents a five-pointed star stamped either before or after the serial number. The star is found to the right on most of these clocks until about serial number 2500 when they began stamping it to the left.Okay, thanks to everyone, but I am still confused. Did Grivolas purchase the movement from Jahresuhrenfabrik, add the two protections to the suspension spring assembly, and then install it in a French case? I thought Grivolas was a manufacturer of their own movements, but evidently they were more than that.
Kamil, I weighed eight Grivolas pendulums of the same design as yours. The lightest was 331 grams, the heaviest 368 grams, average was 348 grams. Two of these were operating with the original Grivolas/Guillaume temperature compensating spring, the other six were with the 0.0040 inch (0.102 mm) spring. I think with your weight at 308 grams you may have to thin the spring a little to bring the clock to time.What is the proper weight of an Grivolas pendulum - and a proper suspension spring for this clock?
I do got a pendulum like on the pictures which weights 308 grams - on which spring it will go?
Gintaras, thanks for posting! You indeed have a "German Grivolas" clock, with the movement and pendulum supplied by Ph. Hauck and the case being sourced from French case makers. Your movement was made in December 1904 based on the movement serial number, and the clock assembled by Grivolas about August-September 1905 based on the Grivolas serial number 720. My research now shows that Grivolas started making 400-Day clocks using the same business model already proven by Bowler & Burdick. That was to purchase German movements and pendulums and place them in high quality French cases, using their own dial and sometimes other parts.Last week bought Grivolas 400 day clock. The clock requires some restoration so posting at first only movement pictures. Unfortunately top block, fork and bottom block are missing. Disc pendulum have the same serial number as movement have. I read completely this thread and guess now that this is Grivolas with German movement - I am not sure is it Hauck or Juf. Any information would be very interesting.
John, thank you for very detail information. i will post additional pictures after finishing restoration. Can you take a look to my other posts which were left without your attention?Gintaras, thanks for posting! You indeed have a "German Grivolas" clock, with the movement and pendulum supplied by Ph.

This business appears to have started near the end of 1904, about the same time Charles Edouard Guillaume patented his temperature compensating suspension spring made of one section of steel and the rest of INVAR. The steel section loses strength with rising temperature, however the INVAR is heat treated to increase strength with rising temperature over normal ambient temperatures. The lengths of each metal are calculated so that the loss in the steel section is exactly offset by the increase in the INVAR section.
Grivolas evidently collaborated with Guillaume to test the spring design, quite likely using movements made for Swiss inventor and clock maker J. J. Meister. In 1892 Meister had invented the first temperature compensating torsion pendulum using a bimetallic split-ring "disc" with adjusting weight screws spaced around the perimeter, and Grivolas was working with him from around 1900 up to 1908 to improve the operation of that pendulum design. When Grivolas started his own business, these springs were offered at additional cost on his German movement clocks. I have documented more than 20 Grivolas clocks that still had their original Guillaume temperature compensating suspension spring, which is quite accurate being comparable to Horolovar suspension spring performance.
Regarding the "German Grivolas" clocks, about 3,000 were made between the end of 1904 and about October 1908. Ph. Hauck was the first supplier of movements, I have documented these with serial numbers between 5300 and 13700, supplied between Oct. 1904 and Sept. 1906. The only other supplier was JUF, who provided movements with serial numbers between 54900 and 68000, supplied between May 1906 and March 1908. Grivolas applied their own serial numbers to each of the movements and also stamped them on the majority of the pendulums but apparently not on your clock. These numbers started with a low number, so far the lowest recorded is 99. They were applied sequentially but did not necessarily keep exactly in synchrony with the movement serial numbers. The highest recorded so far is 2930.
When you complete restoration of your clock please show us the photos.
