Well I used to have three of these! It was a case of "Buy Two, Get Third One Free!".

Two had blue dials while the third has a brown dial....but despite all three watches being essentially the same watch, the writing on all three dials is slightly different.

These Swissonics contain the ESA 9150 electronic movement; for details on this and other ESA electronic movements plus a Service Manual for this watch, click here.
