Hey, so I have a question. I've got an Invicta dive watch with a NH35A movement here that whenever I unthread the stem and crown as it is unthreading the date starts changing. Once its unthreaded I can change it to the 1, 2 and 3 positions and set and wind it accordingly. How can I fix this and what is causing this?
Yours truly, Josh

Question for those who work on Vintage Timex watches:
I've restored several Timex pieces from the late '60s to the late '70s. The technique I learned (from Internet posts and tutorials) say to simply loosen the dial-side balance pivot by unscrewing it 1/2 turn prior to cleaning the entire movement in an ultrasonic cleaner. This method contradicts the official Timex service manuals, which state that the balance should be removed, cleaned separately and reinstalled. Thus preventing the hairspring form being damaged in the ultrasonic cleaner.
My experience is this:
Leaving the balance in place (slightly loosened) is much easier and will work on the standard movements used in the '70s (M24/25, M32/33, M104, etc.) Attempting the same method on movements from the '50s and '60s (M22, M29, etc) will result in a kinked hairspring that is damn near impossible to un-kink. So my question is this:
What do you experienced Timex restoration experts recommend? Leave the balance/hairspring in the movement for cleaning, or take it out to soak in a separate jar?
Is the potential for hairspring damage greater when removing/reinstalling the balance - in comparison to leaving it in place?
I've messed up a couple of vintage movements that I really wish I hadn't. I don't want to make those mistakes again.
Thanks for any insights!

I honestly just wanted to know how much it would cost me to fix my meylan stopwatch no. 214 if I were to send it to meylan to fix. I feel i should because on the inside the bezel case said to. And if I choose to send it to meylan then do i just send it or can I set up something online because on meylan's website I can't find anything about repairs or my stopwatch in particular. If you can help with some answers I would greatly appreciate it.

Good evening everyone. I am new to this forum and i can see we have some outstanding experts on the site.
brand new to watch repair and looking to get some advice. I purchased an Omega seamaster quarts 1342 watch (not currently working and not tested) as it was a bargain and understand that 329 is the equivalent of the original mercury battery used when the watch was manufactured?
I am hoping the battery change will mean it is functional but in the event it does not work, how easy/costly is it to repair. (I’ve heard parts can turn this bargain into a money pit)
would anyone in this community willing to have a go at fixing it after i try battery change?
paid service of course.
any help advice would be much appreciated
thank you

Hello All,
I am relatively new to this hobby. I am an electronics engineer by profession in Los Angeles. I have been designated as the go to person for replacing watch batteries and fixing vintage & modern electronic gadgets for almost my entire life. Recent past, my father told me in casual conversation that his watch was running slow. I didn't know until later on that it was an automatic movement, which got me down this slippery slope. Since then I have downloaded time grapher apps, bought a dedicated chinese time grapher, purchased a set of tools that would rival Marks workshop...lol. I tend to do that, get hooked and immerse myself in things that interest me. I am an amateur radio operator, machinist, wood worker, photographer...on and on. I have learned a lot about a lot of things and have been successful in using that knowledge which keeps me motivated.
I fix and restore old film cameras and have a collection of prized fully functional 40's through 1981 SLR cameras. I got so good at it, I had a steady stream of people willing to pay me whatever I wanted to get their vintage/classic cameras re-sealed, cleaned, lubricated and adjusted. I no longer add to my collection since getting married....lol. But always keep an eye out for a rare find. Before the above, I was into machining. I have a full machining table stop workshop. 14" lathe, 24" 3-in-one lathe/mill,/drill, belt sander, grind/polisher, assortment of dremels and many other goodies. I also learned to MIG weld. I built up a dune buggy single axle carrier trailer for my brother-in-law to drag behind his truck (still in service 7 years later). That was a learning experience. I watched lots of videos and talked to professional welders. Ended up doing exercises of all kinds of welds and cutting them open to see the depth of penetration to learn how to dial in my machine for various thicknesses.
I have many other interests that I have embraced and learned by doing, going to spare you the rest LOL....I am passionate about learning.
My current projects:
1). Refinishing the cabinet and restoring the electronics on a 1930 Philco Model 77 low boy radio.
2). Refinishing and restoring an old library cart. My wife and I have plans for this, maybe a mobile bar LOL...
3). Making a kitchen knife set for my wife. I know, easier to buy, but for me it's all about the journey. I made my first Santoku and she uses it a lot. Bought metal blanks, shaped and grinded it (via printed template from pictures) into what looks like a pretty good knife that holds its edge well.
4). Restoring a 1980 Star Wars themed alarm clock. I have the old record player mechanism working. The Bradley wind up clock is running slow even when the external speed adjustment is maxed out at the ++ mark. That should be a learning experience.
5). Assembled an ETA 2824-2 movement watching Mark's and other videos on youtube. It is in a beautiful watch now (for my dad's birthday) that I built from German and Swiss part sources. I ran into the problem where the stem would not fit back in the mechanism while fitting a new stem/crown to the case. Thanks Mark for the detailed video on how to fix that, took me about 1 hour of trying various things before I figured it out. Watch works wonderfully, in beat in 5 positions and my worst is +3 seconds per day, stem up. Dial up it bounces between +1 and 0.
I will ask a lot of question so please bear with me, this is all still new to me :)

Just trying to get my head around how this works. When the jaws (operated by the stop/start button and column wheel) are under the clutch and lifting it up - chronograph disengaged. Is the second wheel still turning part of the clutch? -
This is x20 magnification. I can get up to x270 mag with an optional eye piece. X70 in current configuration which is great for looking at wheel teeth, jewels and hairsprings. Plus progressive linear zoom from x20 to x70. I love the well made piece of equipment. Sent from my iPhone using Tapatalk Pro -
