I do my best to use visual cues to pair the same watch posted at different times. The watches represented on each row in the table below are intended to be unique, though given serial numbers are often not shown for images, the same watch may appear multiple times. The range above is extremely limited due to few of these pieces available, and for many shown, most without visible caseback images, or otherwise without serial number provided. This range will increase as I receive more information on these pieces. Ranges I have seen for the white dial Big Eye: 2370276 – 2380565, corresponding to roughly late 1964 – 1965. If you find others, please contact me with a link and/or images and serial number if available.
Below is an aggregation all of the *white dial* Universal Geneve 884100/02 “Big Eye” pieces I have found.
