There is a great HODINKEE article on split-second wristwatches by PH Zhou, entitled ‘In-Depth A Detailed Survey Of The Split-Seconds Chronograph And Its Cousins’ – absolutely required reading for anyone interested in split-seconds pieces.
The article includes a reference, with image, to a ‘Venus 190 by Tourneau’ as available on eBay in 2015:
In conversation with the seller from Poland to learn more about this Tourneau split-second, they indicated that they “made this watch by myself.” They further note that the “Case was stainless steel…made by myself…dial was original..Venus 190.” I don’t have any reason not to believe the seller, but if anyone has additional information, please let me know. Here are some other timepieces from the same seller for reference.
I am including detail on this specific Tourneau as the HODINKEE article is widely read, and I wanted to pass along the information for other readers of the article as I believe it may be of interest.
Again, the HODINKEE article is otherwise extremely well done.
