Anonymous, Swiss, probably specially made for the contest at the Neuchatel Observatory. Notes Note: Although this watch has a movement in grey. the craftsmanship of the escapement and the tourbillon is of the highest standard. It is almost certainly a masterpiece made at the Technicum of La Chaux-de-Fonds.
