It has been a long time since anti-magnetism was a novel idea when it comes to watches. Over 100 years in fact. Magnetic fields can wreak havoc within a watch and cause the hairspring of a mechanical movement to stick to itself, causing the watch to run fast. This is why dating back to the 19th century, great manufacturers like Patek Philippe tried to use hairsprings made of metals less susceptible to magnetism and experimented with various alloys. Unfortunately, these tactics didn’t yield great results. In 1915, The first anti-magnetic pocket watch was assembled by Vacheron Constantin, but it wasn’t until 1930 that Tissot would bring true anti-magnetism to a wristwatch. 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. This watch, fitted with a calibre 27T represents Tissot’s important contribution to an important yet often underappreciated watch feature, anti-magnetism.
The 37mm chromed brass case is in fair condition. As with many chromed watches that have seen wear, the base metal is showing through in spots. Specifically on the underside of the case by the crown. The cases’ large (for the time period) size, broad bezel, and sculpted lug strike a nice balance and create an overall design that is both highly vintage and highly wearable.
The Dial and Hands
The cream dial is in fair condition. It features applied numerals and hands in gold tone with a printed outer minute track. The dial has taken on a fair amount of patina and it is hard to determine the case. The overall result is attractive.
The watch is powered by a manually wound Tissot caliber 27T movement. The watch is running and the service history is unknown. The serial number of the movement (2,5XX,XXX) indicates that it was produced in 1951.
