Wasa

Wasa was an ebauche manufacturer in Pieterlen near Bienne in the 1920s and 1930s.

Wasa was founded by 1925 in Perles-Pieterlen. The company's early products included 8.75 and 10.5 ligne anchor ebauches advertised as having very good quality. The company also provided finishing services for others.

On May 29, 1926, Hans Sieber left the company.

By 1928 Wasa had added extra-thin movements, movements in the style of Patek Philippe, and a 6.5 ligne oval movement.

Ernest Schwab-Kaiser left the company's management on October 3, 1928, replaced by Hans Baumgartner of Grenchen.

Wasa had grown by 1929 and was offering quality, prompt delivery, and acceptable prices.

The company promised "a new baguette calibre which will be a real surprise to you" in 1931, announcing the "marvelous" 4.25 ligne Cal. 220 shortly after.

The company came under control of Ebauches SA in 1932, with Robert Neuhaus and Ernst and Fritz Baumgartner departing from management on May 4. They were replaced by Sydney de Coulon, Hans Baumgartner, and Virgile Juillerat.

But the financial situation was too much, and Wasa was bankrupt in 1935. On March 28 it was announced that Wasa would be liquidated. The company was removed from the books on December 23.
