Felsa 4009 service


Recommended Posts

Nothing special to report here but this Felsa feels kinda different than the other watches I have worked on.  Granted, I am an amateur with limited experience. 

The open mainspring barrel was a surprise for what appears to be a higher-end movement--kinda EB8800 feel.  Frankly, I left it untouched.  It is my watch from my box-o-watches, and I was not in the mood for dealing with an odd mainspring configuration this evening.  Maybe next time. 

The automatic wind mechanism was more integrated into the movement than the ETA movements I have worked on.

Lots of springs.  Ugh.  The click spring was the most unusual that I have seen. The plate screw shares the click...essence of Roskopf.  It is almost all back together now except for calendar works.  I will finish it tomorrow.

The Felsa 30 jewels version  is a true workhorse, better yet the  41 jewels variant, heres one in vintage Fortis Stratoliner ,

I see the link gives error,   Google will bring you images of the watch. " Vintage fortis Strstorliner "

The self winder module integrated in mainplate is unique, not to mention other details. Beautiful pinion leaves, etc.

I have a 30J Felsa 4000N. The auto winding is a bit unusual, but works well. I was impressed by the overall quality. It runs really well. You can buy them surprisingly cheaply. I thing they are an under estimated and great value movement.

I was going to ask about quality. On one hand some parts appears to have a bit beefy and engineered while others have that cheap stamped look about them. 

Do we get to see the dial?

 I don't know about its hairspring quality, but major part of the rest is superior to ETA, jeweled winder rotor bushing and jeweled barrel arbour bushing,  in 30 and 41 jewel versions, excellent pinion leaves, day changer a bit lazy however.

    • So fsr as assembly, I don't think you would find 5646 different from 5606, just that GS is 36000 beater. No unknown chalange is there as long as the escapement reamins undameged. Rgda
    • no, I have no alternatives and don't know of any. I've bought Mobius and that's all I have. 9010, 9104, 941, D5, 8000 and Moly-Kote.
    • I've just had the wood stove door seal replaced. I was hoping not to need to do that again for a few years. In the name of science I can't say I'm not tempted. I mean how dangerous can it be? Says the man who encouraged his friend the plumber to use phosphoric acid to dislodge the solidified sodium hydroxide that had blocked the bath U bend. We did take that outside first though, and yes, adding concentrated phosphoric acid to sodium hydroxide crystals and drain sludge is as bad an idea as it sounds.. so we did it several times, laughing like delinquent school boys until the explosions of brown goop stopped. The operation was a success, but sadly the patient died (or rather, melted), and we had to replace the U bend anyway.  Children, please don't try this at home.
    • I don't usually fancy the yellow crystals but it seems to work with that dial... ...and you can't set fire to it unless you share video. I speak for all of us...
    • For the last couple of evenings, I've been working on an Amida 15 Jewel based on the Amida 500 movement from sometime around 1950. This is a slightly odd mechanism, as it has the initial appearance of a jewelled lever arrangement, but is in fact a pin lever. The movement is well made, and pretty easy to work on. After a little swithering, I did change the crystal. It looked original, and I would probably have left it alone, but it had yellowed somewhat, but the thing that sealed its fate was the crazing that became evident if the light struck it from just the right direction.  As you can see, it made a marked difference to its appearance, although some might argue that the yellowing gave it a warmer look. I'm in two minds also regarding the hands. I suspect they might polish nicely, but the nagging voice in my head is saying, they might also end up looking uneven. It does run reasonably well all things considered. It doesn't quite qualify for the 404 club, as it came in at a rather too hefty price tag of £4.99 GBP. but since I've made a few other exceptions to the rules recently, it may just get an honorary membership. There are a couple of other issue I need to address. The first is the fixed pins and rather small lug width, which measures at a rather odd 15.3mm. I'll either need to source a strap, or perhaps use this an opportunity to make a custom sized strap for it.  The second issue is.. do I dare set fire to the old crystal, just to see if it is made of nitrocellulose? If you hear a loud bang and detect the smell of singed eyebrows, then you will know the answer.
