The first real quartz watch after the Tuning Fork!
This watch does have a jumping second hand instead of the smooth gliding second hand of the F300 Tuning Fork which was signed on the dial with ETERNA SONIC electronic.
Signed crown, the glass is signed with the famous 5 dots inside. Eterna did make different models with this calibre using different dials.
Size of the case is 37 mm. without the signed crown x 43,5 mm. We can talk about a BIG and beautiful watch with mint hands and dial all you see is a reflection.
The blue dial has a non-brand steel strap from that time, the silvered dial has an original strap.
They were made in different colours.
