Early Durowe 7423 broken click spring - hacky temporary fix

Recommended Posts

Sometimes the "well there's your problem" issue is immediately apparent. 

Going through watches accumulated years ago, opened up a Buren manual wind watch containing a Durowe / INT 7423. Click doesn't click. 

Dr. Ranftt's database indicates that later versions had integrated click and spring, and i can see why. 

If I were a liar, i could claim that probably a previous investigator installed the click wrong and flattened the spring. But no, it's clearly broken. 


And filthy! lots of liquid oil all over the barrel bridge. 

My initial thought was that maybe the wire crescent style click spring could be retrofitted and that maybe i have a spare from a parts movement, but i don't. 

Yes i know i should just replace it. I have already found a couple sources. I'm on it. 

But a guy's gotta try, particularly when considering that it might be weeks before a replacement spring gets here, but i want my gratification to be instant!

So i bent it. It works. Not sure i should be proud of that. 


Timegrapher said it was running 300+ seconds a day fast. There is a lot of random crud in the barrel along with the drenching of oil - maybe remnants of an old grease?

There are at least 4 service marks on the inside of the case back, so someone cared for this early 70's piece for at least a while.

Took less than 3 weeks for the replacement to get here from Garofalo in Italy. 

They sent me 10 of them taped to a bit of soft tissue in an envelope. 

I can see why these are the "early" version, why they are out of stock in the states, and why they sent me 10 of them. They are such bullshit. The first one i installed broke straight away. 

So if anyone needs one, I can send them two in a crush-proof container of some kind. 

The Borel database indicates that they fit several Durowe / International movements starting with 74 and 75, several Standard Time movements, and a few wittnauer and universal movements:

    • Plastic crystals have a lot of stress and this will eventually show up as a lot of hairline fractures on the crystal. If you are saying you want to save the original I would recommend not bothering they are considered consumables. Get an original crystal installed by a proffessional is the best route. Not much difference in price to buying one from them and installing  it yourself. Anilv

    • I have a few questions on the use of a (lever-type) jeweling tool in the adjustment of jewel endshakes, as I have never done this before. 1. If the endshake is too much or too little, how do you choose where to adjust the endshake? Do you adjust the endshake on the train bridge, or the main plate, or both? How do you decide which is the best? 2. When inserting the pusher into the spindle of a lever-type jeweling tool, such as a Favourite, is the best practice to take out the entire spindle from the tool frame to insert the pusher? And likewise, take out the entire spindle from the tool frame to remove the pusher? Or is it perfectly ok to insert or remove the pusher when the spindle is still inside the jeweling tool frame. Which way is safer/ best practice. 3. Is there an attachment to the base of the jeweling tool to hold the mainplate or bridges? I don’t seem to see any for sale, new or otherwise. Can I make one?
    • In the USA, you could try: https://www.jewelerssupplies.com/ or http://www.julesborel.com/ Cousins in the UK might be a possibility (although Waltham is a US watch, I'm sure some of them made it across the pond). https://www.cousinsuk.com/ Mark also has a list here: https://www.watchfix.com/category/watch-parts-tools-suppliers/watch-parts-tools-suppliers-us/
    • Yup. It's like the song from The Greatest Showman.... Never Enough! Never, never...
