1986 Submariner has Sunk

[k11ngc]

Hi All,,,
Could you help me find parts for my 1986 Submariner Date,Model 16800 (Calibre 3035 Hi beat.)
I stupidly forgot to screw in the crown after ajusting the date and then cleaned the car, so it got a little wet.
So I now have it with this nice old retired rolex watch repairer, Living local to me, But he's not internet savy, So not being able to locate parts for it, Such as 3rd wheel 4th wheel and escape wheel, (also have lost click spring between repair shops and my man).
Have gone on line and there are some places in the states that sell Generic Rolex parts for my whatch @ $18 each wheel but only the 3rd & 4th. Iv'e owned this watch from 1992 and feel lost without it, it's been on my wrist as a motorcycle courier, for 9 years, its waived to Princes Diana in traffic, and got a smile back Ha Ha. Any way I'm in need of these parts so could you point me in the right direction Please Help..Steve H
