IWC Electronic with Integrated Bracelet, Tuning Fork cal150 in Solid Gold


What is beautiful, hums like a bee and is yellow (gold)? Exactly, a bee. But a tuning fork watch in solid 18K yellow gold, as well.

This one is an excellent preserved example made by IWC in 1972 / 1973 -- with no relevant signs of wear and unpolished. The watch is not only beautiful in its appearance but solid and thus heavy. The sweep second is a mesmerizing feature of the fantastic tuning fork movements humming at a frequency of 300Hz -- make sure to read the relevant blog articles on our site, to understand our enthusiasm for this technology -- and the gentle vibration that could be heard and felt on the finger tips is something that simply isn't available with purely mechanical watches.

The milanaise bracelet is of course original to the watch and currently fits a 185 - 190mm wrist. One small part of approx 15mm was cut off but is included (see last photo) and could be inserted by a goldsmith again to make it fit even a +200mm wrist.
