LEGEND. You helped me replace my batteries. The AC touch had me stumped ... hey presto, my vintage 2737 LIVES. THANKS mate. Nice job.

I have the same watch and thank you for your help in replacing the batteries and the all important AC touch.
without bragging my watch was washed and cleaned with washing up liquid and wow it really did the job. how did wash the watch face without getting water inside?
So how much should i be asking to sell this really nice looking retro G Shock?

Oh I just use a tooth brush. And it should be worth around $100
