In my perusals of eBay I became aware of the watch brand Sicura. I also learned that they were the company that rescued Breitling from oblivion in 1979. I came across the Sicura Satellite with it's large chrome plated case, metallic blue dial and its enormous seconds hand. I was able to acquire one that needed attention on eBay for a reasonable price. When it arrived I discovered the crystal was trash, they date wouldn't change and the watch would stall after a few hours. Inside beats a Swiss, Baumgartner, BFG 158 31/7. This is a manufacturer I personally never heard of but I would become very intimate with over the next few weeks.

I stripped the movement down and during disassembly of the date mechanism I discovered the Day/Date advance wheel pivot shaft had worked itself loose and the day advance wheel itself had dislodged and was wedged under the cover plate.

I continued the complete disassembly and found no further issues other than general filthiness with oil everywhere.

While disassembling the mainspring to clean and lubricate it, the arbor popped up and caused the spring to exit the barrel in a knot. Thankfully, no mainsprings were harmed in the restoration of this watch, although my nerves definitely were tattered.

During reassembly I pulled the Novodiac shock springs to clean and lubricate the balance jewels and the lower spring pinged off. Thankfully I found it a week later.

I ordered and installed a new crystal because the original shattered when removing it

I assembled and tested , disassembled, cleaned reassembled, rinse, and repeat no less than 5 times trying to get it to run correctly. I used the wrong oil and it was stalling the movement. It is currently running without any lube which I will correct after I take delivery of some Moebius, but at least it's running and keeping excellent time! I took delivery of a silicone strap last night with blue accent stitching and I really think it looks the Business.

Nice job. You resurrected that watch. You will find Baumgartner movements on many if not most Sicuras.

They're not bad movements. Not as bad as the cheap and simple EB stuff but maybe not as good as some higher grade ETAs.

The quality of the watches themselves is alright but from my experience they often time didn't resist the test of time like other watches (sometimes from less known brands).

Thank you. Was a very educational experience.

To whom it may concern, be careful when working/cleaning the inner bezel/chapter ring. The old paint will come off/flake easily. I speak from experience. :)

On this watch the inner bezel/chapter ring sits in a shoulder in the crystal itself. I had to order one of those crystals with a tension ring inside the opening to accommodate the bezel. Because the original crystal was so stuck inside the case it crumbled while trying to press it out. I poked around with a screwdriver trying to pry out the remaining lip. You can see a scratch I made at the "55" position when the screwdriver slipped. :startle: Just another page added to this watches story.

Nice job. I have some BFG 921autos which I got NOS for practice and they are easy to work on and reasonable quality. 

I like the strap, where did you source it from as I am interested in one for my own watch ?

Thanks FLWatchguy73 for the PM.  Could prove a little expensive for me to source from USA to UK.  I will use the info though to try and source nearer home, many thanks.  For the benefit of others using this forum  I have attached the link below, hope you are ok with this.

    • Of course, donor movement is needed, but the balance/hairspring assembly itself can be saved. OP, You just have to use tweezers and needle to straighten and two tweezers to untwist if needed to rectify the outer coil. What is seen in the middle may be is because the stud pressed to the spring, but we will need pictures after outer coil rectifying. The regulator and stud carrier are snapp-fitted on the antishock assembly. Lift and pry them together with some sharp tool and they will come off.
    • A good learning piece but think for the price of a new movement that's all it is. Probably just transfer the rotor if it's Citizen branded.
    • I'm no expert, but I'd guess this one is for the bin. Looks like it's been tinkered with by someone armed with a hammer and chisel. When the pallet, escape wheel and balance are all damaged it's beyond repair isn't it? Or a new movement if the watch itself is of value. 
    • No need for special tools. Loosen stud screw and just push hairpsring stud out of the hole.  Regulator arm is spring circled around the setting housing, insert cutting edge of a safety blade under it,  opposit ( 180 degrees) to regu arm itself, and pry  half of the circle up, you then see how it all is made at put together. Remove the mobile stud carrier as well,  reinstal in proper order, first goes on the stud carrier, second put the regulator arm on top and press it home. Exactly as nev explained above. Trueing inner coils is done when balance complete is seperated from the cock.   The part thats bent over itself. 1-Unbend hairspring as much as you can when balance is seperated, just grab the hairspring stud in tweezers , grab hairpsring with another tweezers streighten with  strokes as you  move the second tweezers  away from the stud. 2-Move stud carrier and regulator arm as wide/ apart as they go , to provide max space which comes useful in next step. 3- Fit hairspring stud, into stud carrier hole. 4- Put balance and cock ( when attached together) back on mainplate.  5- You have enough space to grab hairspring in  tweezers to shape as you move your tweezers  away from stud.
