Hello And My Current Venus 170 Project


Recommended Posts

Hi all.

 

I am amazed that I have only just found this forum, but so glad I did, it is a gold mine. To introduce myself, most of the time I am a writer and journalist covering motorsport technology, but in my spare time I've taken to watch tinkering. Like most I suspect, I started off tearing apart watches found for pennies at boot fairs and over the last couple of years, have slowly increased my abilities. I will now happily have a crack at most manual and auto watches and I've also done a few Venus and Landeron chronos. I'm lucky in the connections I have discovered, notably one brother in law having a grandfather who is a watch maker of the old school and another brother in law who's father is a clock maker. They have proved an invaluable source of info and encouragement.

 

I'm steadily building up my selection of tools and an growing a collection of vintage spares (wherever I see old watch parts at markets etc, I'll snap them up). My current endeavours involve learning the basics of lathe work (one of the aforementioned watch makers kindly donated me their spare Lorch 6mm and a vast selection of attachements).

 

As I am sure most people do, I have a number of projects on the go at the moment. The most recent I completed was a full strip down and service if an Omega Geneve Dynamic for a good friend, which had the most perculiar time keeping when I recieved it (ranging from +900 sec/day to -3). This was diagnosed as a sticking hair spring (with possibly a touch of magnetisim thrown in), and after a full clean and new main-spring it was back to keeping reliable time. However; it seemed to me that it had not been serviced for a long period of its life and there was a lot of wear on pivots etc which were beyond my abilities to fix. As such, its positional accuracy varied considerably.

 

This is my current main project, a Breitling 181 with a Venus 170 movement. It was an Ebay find and in a very sorry state, various chrono parts missing, trashed case and a dial that had seen better days. I originally intented to keep it patinated and original, but once it was in my hands I had to admit that it was too far gone. So far, i have stripped it down and Adam George at Watch Case Works has done a grand job on the case. I am now trying to decide on a company to entrust the dial to for refinishing.

 

Who are reliable and accurate?

 

As for the movement, once I source a donor for the chrono parts, it needs a new pallet staff and main spring. I will keep you posted.

As it all stands at the moment

Thanks Geo, yes I have come across them and have requested a quote. It would seem from the literature I have on the 170 that it was a pretty standard dial pattern, simply branded Breitling in the middle. I have previously done a 1191, which was in an even worse state that this one, but with a usable dial.

    • Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!
    • Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?
    • Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.    
    • Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?      
    • Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
