IWC SCHAFFHAUSEN

Blue

1970s IWC Electronic Jumbo Ref. 3403 Cal. IWC 150

We all know the famous Bulova tuning fork movements and the Omega-branded versions it powered – the f300Hz. But did you know IWC also used the same movements? That’s right, the fish crown brand also introduced its own tuning fork-powered watches, the reference 3403 and the caliber IWC 150 (ESA 9162).

Back in the 1970s, this was one of the most expensive tuning fork watches money could buy, at a whopping CHF 1,000. The case is developed from a proprietary hard steel alloy (Durci) with a Vickers hardness between 1,000 and 1,500.

The watch features a gorgeous blue-ish sunburst dial with matching white and blue hands. It also has the original integrated bracelet with a signed IWC clasp. My watchmaker recently replaced the date wheel for a white one, but I’ll also include the original blue date wheel.

Condition: Good. Dial and bracelet look pristine. Case has some wear on the side and back, which is very common with this material. See detailed photos for full condition and clarity.
Case size: 38mm case diameter, 42.5mm lug-to-lug including integrated link.

Crystal: Mineral

Movement: IWC 150 (ESA 9162), tuning fork with 12 jewels and 300 Hz. Service history is unknown, but it’s still running strong. The blue date wheel was replaced with a white one.

- The bracelet will fit a wrist of up to 6.75 inches.
