Wittnauer Automatic

Recommended Posts

I just had a roller coaster on this Wittnauer with an AS 1585N movement. Got it a few months ago and it was running strangely with a hesitation in the seconds hand every few seconds. Almost went backwards for 1 tick...so stripped it down tonight and think it was likely the mainspring / barrel. So got it back together and everything running nice with decent amplitude and low rate delta up versus down dial and low beat error. The kicker was that I tried to let the power out with the rachett wheel screw and the driver slipped and absolutely made a mess of the wheel finish...OMG don't let the children see this...it is awful. Going to see if I can source another wheel. On the bright side the dial is spectacular and it is running nice.DSCN56012.thumb.JPG.ccfe537aa76fcd9dfb83465512d1fd75.JPGDSCN56002.thumb.JPG.3075e1a290a4974cc93e4d7126af7a21.JPG20231127_2143132.thumb.jpg.cef6048d92837220d3eb9a5e30f8a74e.jpgDSCN56042.thumb.JPG.2878fa49e6cfb84369dd1e16d7d17a19.JPGDSCN56052.thumb.JPG.ba144fba7d8d2ef964949f1d80fe74ef.JPG

I feel you pain, I was almost finished with an accurist a week or two ago and had to let down the wind (can't exactly remember why now) and used a screwdriver to wind it down as I held back the click. I had a similar result as you did when the screwdriver slipped and made a horrible spiral mess of the ratchet wheel, to add insult to injury the screwdriver carried on and mashed up the center wheel - not my greatest moment! fortunately I had a donor I could steal from, but more by good luck than good planning.

I always wondered why the guys on the YouTube channels went to all the trouble of reinstalling the winder to let down the power, as using a screwdriver is so much easier...guess I had to learn that lesson the hard way!

When I was in school we always installed the stem and the keyless first. From memory it's because it gives you something to hold onto you now have a stem to grab. But the reality is also you can use it to let the power down or wind the watch up. As I typically work on pocket watches I have a morbid fear of even using the screwdriver do anything with a pocket watch as there's so much force their so much chance of bad things happening.

As far as winding goes like Seiko where there is no key lesson a lot of the early ones then they expect you to use the screwdriver to wind it up. But letting the power off that can always be a challenge because that's a two-handed operation one to release the click and the other to somehow left the screwdriver spin slowly releasing the power well there's a reason why there's a stem on the watch and it's very handy for letting the power off.

Oh don't worry we all make interesting mistakes from time to time. It's how we learn or at least how are supposed to learn sometimes you forget the silly little things you shouldn't be doing and then you get a reminder.

    • Looks that way, if it had any amount of significant jewel count it would say so on the dial. 
    • Light naptha is what you need to be looking for. The carbon to hydrogen ratio is high with heavy naptha, it doesn't evaporate as well as light naptha and is prone to leaving more residue. Try tom's suggestion of the mirror test.
    • Its a big item Michael and a lot that could go wrong with the process of getting it to its new location. I once helped install one of these units into a conservatory that i had built. It was big and bloody heavy and took six of us to get it in safely. If you have sliding doors and you need to remove the whole frame then that may or may not go well. But i would advise getting a professional in if you have little knowledge on the installation of them. The glazing of the doors could well be 6mm laminated glass which again will be heavy very heavy if the glazing units are big. The glass would also need to be set up and packed correctly to open the doors properly more so if they are unframed and the sliders are upvc. Seems a shame but if no one is biting and that may be due to having no warranty i guess the only takers might be someone that installs them for a living and knows how to repair. If its fibreglass just be careful, i sometimes have to cut fibreglass baths out and they are nasty to work with . Thick gloves are definitely recommended,  not fun picking out fibreglass spells two days later that have started to go septic. Good luck with it all matey.
    • I don’t know anything about this product, however assuming you have it if you put a drop on a mirror or piece of glass lying flat on a table and leave it to evaporate if it leaves any sort of residue it is not really suitable for watch part cleaning.   Tom
    • Well I put the spa on Gumtree (selling service) to try and sell it as it only needs a recirc pump to get it going. However, it weighs circa 250kg, so there's 4 fairly strong guys, and I would have to remove the sliding door in the room completely to be able to get it out, as well as clearing out a multitude of potted plants and the Alfresco outdoor setting to be able to get it out. Then move nearly everything in the back of the garage to be able to push it through to the front of the house. I would also need to hire furniture skates to be able to shift it around as carrying it is out of the question. Then someone would need a trailer to get it to their place as you won't get it on the back of a ute. So, the only answer is, out with the reciprocating saw and cut it all up into manageable pieces. Crying shame as it is in really good nick. I was only asking $1,500 and only got two bites, but it would only take something to go wrong with removing the sliding door etc that everything I make on the sale could go out the door on repairs etc. It would have been nice to be able to turn it into tools etc, but que sera sera. I don't know about the rest of the world, but there just seems to be very little interest from people wanting to buy things secondhand.
