Pcket watch "Art déco"?


Recommended Posts

Hi all of you,

I've just received a pocket watch without any brand name wich looks quite old, and the only information I could see on the movement is 7020. I haven't disassembled it yet, and I must admit I am a bit reluctant to do it as it seems old (but it works well).

Could anyone help me? Here are some photos.

Lovely dial. 15 jewels and Breguet overcoil on the hairspring. Have you got a pic showing all the movement, i.e. looking from the crown?

I've no idea what the movement is, it will be easier to ID once out of the case and measured.

Might be able to identify it once the diameter is given and a photo of the keyless works but no guarantee. 

Ancre-----Lever escapement
Levees visibles---visible (jeweled)pallets
Double Plateau-----double roller
Spirale Breguet--Overcoil hairspring
Balancier compense----Compensated balance wheel
15 rubis---15jewels

Looks to be in good condition, and fairly modern.  I've never seen a bent regulator arm like that. Also the click is in an odd position. Should make identifying easier.

I found a comment suggesting that Cortebert are known for curved regulators

@mikepilkThank you for your reply. Here is another picture.

This is more complex than a standard pocket watch owing to fact it has 2 driving springs. A mainspring and a smaller spring that acts directly on the escapement. This direct spring provides a more constant torque helping to maintain isochronism and doesn't suffer the energy differences that a mainspring does delivering power through the gear train. The mainspring keeps the escapement driving spring wound up.

I have one very similar to this, i wouldn't disassemble it until you are ready to.

Rich, this one seems rather regular movement to me. Yes, what You describe exists, but I doubt that the one on the picture is something similar.

I'm with @nevenbekriev Rich, it just looks a normal movement to me .... unless you know differently.

Do you have pics of yours? Who is the manufacturer?

It seems this topic is becoming very interesting 😀. Here are two more pictures that might help to identify the movement.

The diameter of the dial side is 40mm, and the other side 36,5mm.

I just broke my Rule #1 - Do not buy a watch unless you can see a good pic of the movement.

I currently don't have anything to work on (itchy fingers) and as I just got this for £20 from ebay, (sold as "working"), I thought it was worth the gamble.

I liked the look of it, It has 21 jewels, so I'm assuming automatic. The back says "Incabloc" and "waterproof", so it looks to be reasonable quality. The case looks good.

From the little I've found on google, the Credos Lugran company was formed in 1954., and bought by Bucherer in the 60s. This looks 50s-60s to me. There's a reference to using good quality ETA movements. I hope so.

I thought i read Remontoire inside the case ?

If it has a e on the end, Remontoire then yes two springs, without the e, stem wound.

The keyless works used for identification are hidden under the watchmakers side. You would have to disassemble it, you dont need to worry so much about that, doubtful it is a Remontoire as i suggested earlier this morning 🤦‍♂️ but you never know 😁

I recall a video on YT from Steffen Pahlow where he talks about getting himself a Chronometre (for which he paid more than he would have liked), but in his words "I had to. It is a Chronometre."

I am wondering if you have more watch there than what you are aware of? Especially with what @Neverenoughwatches mentioned about two springs.

That's true. It is not a chronometer. As a matter of fact, I got it with another timepiece which is e real one, and only that (not a watch).

I add a few pictures of my Chronometer / watch. no indication of a brand ...

I'm not convinced it is a chronometer, just because it says so on the dial.  I think the two springs was a misunderstanding. 

The chronometer on the dial might just be a brand name, looking back yes i was mislead by the mention of Remontoir inside the case. Still not sure why it says Ancre Remontoir which translates to anchor winder, i imagine that means lever winder which still suggests to me 2 winding springs. I'm sure i have that same watch with chronometer on the dial ,I've never ventured inside it. My missus looks after 90% of my watches , so i will get hold of that one and have a look inside.

Haha no not a remontoire, looks very basic.  Good to see the keyless works, can you measure the plate size to cut down on the search for them.

Can you lay out that brass bridge cover as well please next to the other 3 pieces.

Ok thanks  it was just the brass cover next to the previous 3 keyless parts. Normally i wouldn't have expected that to be used to identify,  but I've searched American,  German and French part catalogs and coming up with nothing for the set lever,set spring and  yoke. I will have another look later today.

There is another way but you would have to measure the stem very accurately.

Its ok blueharp the pictures you provided earlier of the 3 keyless components,  the setting lever, the setting lever spring and the yoke plus the brass cover plate should be enough. If they are not listed anywhere then you are relying on any lettering on the movement or someone that just knows the movement from experience.

I've started trying to use the Betfit, but I don't know which measurement I must take for the caliber. The diameter of the dial side is 40mm, and the other side 36,5mm 🤔.

Here's a size chart. 40mm is about 17¾L. I looked in Bestfit but couldn't find anything close.

    • My thinking is yes it is better if you were to choose this or a tg, although the tg can do more . This way the watch is adjusted specifically to you and your routine. As an example i restored an old Smiths pin pallet watch ( typically an inaccurate movement ) around 3 months ago. Adjusted through 5 positions on a tg initially proved ok but not precise over time.  Having then re- regulated the movement after each week of wearing over a period of 6 weeks brought the timekeeping in much closer, now within 1 minute/week
    • Hi,   was just debating whether to repair a Timex -- so here I am!  
    • Hi everyone, I am Michael and I am completely new to the watch making world. After buying a mechanical watch a couple of years ago and realizing that the time keeping degraded significantly recently...I started digging and got fascinated by the topic!  I disassembled the watch with the Miyota 821a...and this gave the initial spark. Right now, the movement is still disassembled...and I am trying on a different movement my cleaning and lubrication before finalizing this project 😁 I am hoping to find help when I get lost and ask maybe some stupid questions - sorry for that in advance 😉 All the best, Michael 
    • As it is your watch the answer is yes! When regulating a watch for someone else there's no way we can tell in what environment the watch is used and how often the wearer of the watch will wind it. In that situation, a timing machine is a handy tool to get close to something that likely will be acceptable. As indicated by @tomh207 and @clockboy a timing machine is a great way to quickly determine the health of the movement. If you are considering a Weishi I'd recommend the 1900 model over the 1000 model as the 1900 has a gain setting. These machines work well but aren't foolproof. If you want something more advanced I'd recommend the PCTM software from @praezis.
    • Hi guys, I am completely new to watch making and currently I am iterating on my cleaning process to get it right. My current process is a 3 step cleaning routine in an ultrasonic cleaner and drying afterwards in a food dehydrator at 45°C. 10min wash with Elma Red 1:9 at 58°C 5min rinse in distilled water 2min rinse in IPA 99% 10min drying in a food dehydrator at 45°C I have an old ETA 2842 which I use to test the process and the cleaning in general works pretty good...but I found one strange thing during one run I did yesterday. After the 10min wash cycle in Elma Red 1:9, the bright silver balance shock jewel metal housing colored black. Do you have an idea what happened here? Thanks, best regards Michael
