17 Jewel Ebauches Bettlach 8800 Walk Through.


Recommended Posts

OK, I can't just leave all the ETA, Valjoux, and Seiko heads get all the posts! I came across this watch one night on ebay with bidding starting at $9.95...

I put in the lone bid and didn't even notice when I had won it. Well, I figured it would be good for at least the parts as I hear that the bezels are almost always missing on this particular model. The Sapphire Beach has a 17 Jewel pin lever--my specialty! I got it and it looked pretty good on the inside so here go the pictures:

It a rather big case for such a small movement.....its running like a charm and even has quick set date just like the real thing! This watch is something that I've seen only a few times, so I'm lucky to run across it so cheaply. The "jeweled" pin-lever movements being made in the 70's were mostly Baumgartner and Bettlach, and all it takes is a cursory glance on any bidding site and check out what some of these things go for the the 'bay to know that pin-levers are collectible. It is of course true they don't sit and give timegrapher readings like an Omega Constellation...but they've got plenty of personality!

Noirrac  the movement you are working on a EB8800 was the movement that drove my very first watch i.e. over 50 yrs ago.

While my Rolex is still on my bench I have been wearing watches I have repaired and never sold and just kept. Over that last couple of days I have been wearing the EB8800 (see pic) and as I look at it now it is spot on time. It was in very poor condition rust etc but a very easy movement to work on.

Thanks for posting and sharing your own pin-lever stories. I think the design of many of these are fantastic...and the fact that so many of them are still running after many years gives proof that these movements are actually quite robust.  Clock boy you're right: these can be easy to work on, but they can also give an unbelievable amount of angst! Replacing the top plate over the drive pivots, placing the pin pallet and getting the balance to sit properly on the impluse are particularly tricky on these. With higher quality movements, I have simply moved the balance near its position and it practically jumps in and starts up--not so easy with these. Alot of fun. I'll be trying a mechanical alarm wristwatch next.

My gang of pin lever resurrected wrecks:

post-80-0-03659200-1424893268_thumb.jpg

 

L to R

Ingersoll Triumph. New strap & crystal, cleaned & serviced.

Waldman Submarine. New strap & crystal, cleaned & serviced. A ruby mine - 23 of them inside the EB8021 movement.

Cronel. This one was bought as is for £5 and appears to be recently seviced. Haven't identified the 21J movement yet.

Ingersoll Triumph Pocket. The case was so tarnished when it turned up it was almost black, also it didn't have hands, crystal or bow. The hands aren't correct, but they work.

 

The great thing about these is they are all cheap to buy & repair, none have cost more than £20 including parts.

    • I often get an amp drop after i oil the stones with 9415, not sure what difference can be achieved with oiling the teeth.  I guess the oiling surface is very small on a tooth as opposed to on the stones a larger drop might have more drag as the teeth plow through it. I oil with a bristle from a brush now, strangely enough the last movement i oiled five escape teeth and the amp was much higher than i usually get , coincidence ?
    • Who'd have thought to look at the supposed compatible calibres ?  🤔 Frank did 😅
    • I recently helped my mentor to service 7 Seikos and he told me not to lubricate the pallets. His reason was from his experience from the advanced classes that he conducted, his students all ended up with worse amplitudes after oiling the pallets. I have to admit that I had the same problem when I oiled the exit jewel, like so many videos on YouTube show. I actually ended up with worse amplitude.  But now I oil the escapement by oiling the teeth of the escape wheel. I think Rolex used to train their technicians this way. I find that I get about 20° -40° increase in amplitude oiling the escapement this way. I've only started playing with epilame recently. I got a bottle from a Chinese seller on AliExpress. It's supposed to be Episurf Neo but everything on the bottle is in Chinese. When the bottle arrived, half of it had evaporated or leaked. And when I brushed on a thin layer on a mirror, it dries rather slowly and even feels a bit tacky. When I did the oil spread test, like my experience with stearic acid, the treated and untreated surface of the mirror yielded similar results. The contact angle of the oil drop looked about the same for both the treated and untreated surface. When I epilamed an actual pallet fork, the escapement was so sluggish that I couldn't even get 180° amplitude. I dunno if I got conned by the seller but the results are just not convincing.
    • I usually just use 2 pair of pliers to remove the roller ( just kidding  🤔 )  I want one,I have an adjustable free standing one. But i really like the little bradux tool that nips under the roller with two tapered jaws that lift it off. You can get under a scope with it to see in detail how the job is going. There is some technique involved to stop you chopping the staff, doesn't particularly matter if the staff is already broken but it naffs up the tool's jaws if you crunch the staff, and the jaws need to be in good shape to prevent damaging the roller. But well worth a try if you've never used one and you can find one that hasn't been misused or buy a one new. The trick is to keep one of your fingers between the two arms to soften the squeeze, with a little practice its a handy little to. I will now prepare myself for an onslaught of negative feedback on it 🤣
    • With luck even possible to fit your 13 lin. movement at all 😀. Those numbers are from 5 1/4, 8 3/4 and 13‘‘‘ sizes, with very different balance wheels! Frank
