IWC Electronic 3403 hardened stainless steel 1000 vickers – tuning fork – 1980

Something special from  IWC.

The reference 3403 was released in 1980 and showed up in the catalogues until 1982. It was one of many “electronic” marked tuning-fork movement watches.

This version comes with an integrated steel bracelet and the whole watch is made of special hardened stainless steel with a hardness of the surface of 1000 – 1050 vickers. This is a very unique pice for IWC.
The blue sunray dial has shaded of dark blue and gray. The baton hands have a blue inlay!

The tuning-fork movements beats at 300 Hz and is equipped with 12 jewels. It sounds like a little mosquito thats trapped inside the watch. Powerfull though!

Overall good conditionm of the case and bracelet.
Bracelet has some patina on the inside.

The watch will fit up to 19 cm without any problem and still has one spare link available.

The hexagonal case defenitely gives an absolute vintage feeling to the wearer.
Its a stunning heavy piece of stainless steel!
Comes with a vintage IWC service certificate.
