Hello, I would like to know about this watch, very thin quartz watch with white roman dial by IWC. I checked the movement and identified Cal.602, which is also installed to Jaeger-LeCoultre watch. I think the reference of this watch is 3801 and produced circa the 1980s. Does anyone know about this watch or similar watches with Cal .602?
How about you take the back off the case, and upload a picture of the movement in the case. Maybe then we can try to answer your question.
I have a 1983 Seiko that looks very much like it. I paid $75 for it, mint condition, with the sticker still on the back, 7 jewel, metal plate quartz movement. And it's probably just as good of quality.
