A bit of history:
In 1930, Tissot introduced the Antimagnetique, the very first mass-produced watch which offered protection against magnetic fields. At that time, even with its basic anti-magnetic shielding, it meant a significant breakthrough in the watch-making industry.
The Antimagnetique line (specimens made for the British and American market were signed “Non-Magnetic”) was in production well until the mid-1950s. Countless variants in terms of movements, dials, case materials, and sizes were produced during that period. With sizes ranging from 30 something millimeters up to well above 40mm. Dials were presented either in white, silver or black, but various two-tone dials were also available.
Initially, these watches were equipped with the calibre 21.7, however, in 1936 the new cal.27 was introduced, and replaced the 21.7 as the “workhorse” of the Antimagnetique line. The 21.7 remained in production until 1938. The cal. 27 family outlived its predecessor by 23 years, with the last derivative, the cal. 27B-9, discontinued in 1961.
All in all, these watches have a great quality to price ratio.
