·Oh, the zig-zag springs. I need to have something like that made for a Gay Freres bracelet. Although not as many zigs and zags.

·Thanks Cristos71, Dan S and Archer. Really learned a lot!! The video was extremely interesting and great to have a part number for the springs!! It looks like mine is the early variation of the 7077 and stamped with 4 58 date code. I also realized after looking at it again the bracelet does have 5 stretch links 3 on one side 2 on the other. Would it be best to have an Omega dealer do the repair?
Would it harm the value to have the crystal polished?
Greatly appreciate it!

·Great, great watch—enjoy it. I'm from MN and my dad's a retired watchmaker there, but (in his opinion) the best place to take this would be Tom Chase, who runs Chasing Time. He's in Minneapolis. He's CW21, and has an Omega account, so can get all the parts necessary.
The only thing that'd harm the value of the watch would be having the case polished. The crystal should absolutely be polished, and that won't affect value at all.
Congrats again. Those old Seamasters are fantastic watches.

·Just FYI - being a Cal. 500 series and a "Bienne only" caliber, Omega does not sell "all the parts" for this movement, so some parts would need to be sourced on the open market. For example the third wheel and the rotor pinion are two common parts that I replace in these movements, and neither are available from Omega.

·At least with the 500, some of the 470 parts are interchangeable. The rotor is also changeable with the 490 but not the wheel train as the 490 is a sub seconds automatic.
On the 470/500 the third wheel is a double wheel for the sweep seconds. On the later 550/600 base, these are seperable. On the later variants it it easy to break the long pivot where it passes though the plate. Not sure why the third wheel on the 470/500 would be as prone to failure, although on the rust rats, the third wheel pivot does tend to rust the most.
Perhaps @Archer might know if they trend to wear more then other third wheels.
At the moment these third wheels and rotor bearings turn up often in the secondary markets. Downside is that they are often from parts watches or scrapped out movements sold by estate sellers.

·Thanks WIcutter, Archer and sheepdoll for your information and guidance. It is really helpful! The more I learn about the watch from everyone here makes me feel very lucky to be its caretaker. Thanks again everyone for generously sharing your knowledge.
