Superocean screw down crown


Recommended Posts

Hi all

My Superoceans crown only screws down about a half turn from when it catches till when it is tight. Is this correct? Feels like it should screw down further.

if it isn't right, any advice on sorting it out?

thanks

Take a Magnified look at the Case Tube threads and verify if they are in good order first, There may be crud built up in the crown or surrounding area. Check the crown itself for proper threads and cleanliness. Post pics and report back.

Remove the stem, and inspect, and clean the threads of both the tube, and crown, I have had instances where some crap has built up overtime, and bedded in the recess of the crown causing the symptoms you are experiencing.

If that so you will need to take the movement out of the case. A good way of cleaning inside threads is use peg wood you will get a thread on the wood but just shave it off with a pocket knife and repeat until clean. All the above advice about the button and stem also should be undertaken that way you will have a good fit as if it were new.

    • Can you get a top view with power off, balance at rest? The hairspring could be off center just enough that it is touching something when running (center wheel, stud, regulator). Thing is, on older stuff in particular, if you find a balance complete there's about a 99.99% chance the hairspring of the new balance will need some adjustment to work correctly.   Also, not much use getting concerned with the rate until you get the amplitude up.
    • Those pins look awfully tight. Does the hairspring slide freely between them when you adjust the rate?  
    • John will ask this question anyway: how did the watch run before your service?
    • I have demagnetised. I would say the hairspring looks fair, mostly evenly spaced though not perfect, no coils touching. I don't have the skills or equipment (an adequate microscope, a good way to remove and replace the hairspring from the balance wheel to work on it) to improve the hairspring so I would need to source a NOS balance complete. I will give it a closer look though.
    • Haha ok so let us begin . Yes the oats tin is a temporary modified heat reflector/ retainer until i find something more..... lets say  " the part " looking. No not mcgyvered but an A Team special reconstructed spinney thingymabob whirlygig device.  The speed of both the drill and hairdryer are controlled by a very sophisticated and complicated piece of apparatus called a " SPEED CONTROLLER " at the extortionate price of £15.99 . No i dont need to hold anything the drill is in a cheap drill stand ( cost £5 for both from a carboot sale ) the travel on the press is 85mm which is enough to lower and raise the basket in and out of the cleaning jars. The " speed controller "  😄 is just a voltage regulator and usable on just about any electrical device to control the speed of a motor or heat output within the full range of a domestic AC electrical supply. Shellaced parts i hand clean and dry separately, i dont risk them at all, shellac will start to melt at around 65 °. The timer , yep an old Smiths timer, i think that was a quid and the white appliance is a food dehydrator, i rarely use that now, i think parts need to be dried quicker than that can achieve. I think thats covered everything.  Feel free to ask anything else. Besides the basket you are looking at around 100 quid in total for everything you see here including the ultrasonic and the dehydrator.  The ultrasonic i also rarely use , combined with an ammoniated solution ( elma wf pro , which i desperately need to use up and not buy anymore ) and it's cavitation action it is too bloody aggressive imo.  I also have something even more diy-ish, simpler, cheaper and more portable  that i like for cleaning right next to where i work on my bench. What do you need for cleaning ? A solution that cleans and rinses well that leaves no residue and a device that spins your parts round and around through the solution with some added method of agitation, there are a multitude of ways to achieve that and it does not need to be complicated or expensive, trust me . What you are paying for mostly with the average proprietary machine ( I don't mean 1000's for automated) is mostly a little bit of convenience, i bet i could swap my jars out as quick if not quicker than something like these machines you are looking at.  Ps . I'm also impressed you managed not to laugh,  i would have 😄
