Tissot was the very first to launch the ‘Anti-magnetic’ watch in the 1930’s, and they stated it clearly under the brand name on the dial, as you can see here. Within the same year Tissot and Omega joined venture in what was named SSIH “Société Suisse pour l’Industrie Horlogére” and Lemania Watch Co. joined in on a later date. Occasionally you can actually notice similarities between the watches, who knows maybe they swapped ideas.
The Swiss Tissot manual wind caliber 27 was launched in 1936, with a large number of family members, with slight adjustments and/or additions, they were in production till 1961. The movement has a balance protection in place which they named  ‘shock resist’, the cabochon ruby is held by 6 clamps and absorbs the jolts. The two-tone dial has aged beautify to a gold/bronze/olive shade. The outer black ring is interrupted, by the sub-second which has a small black ring around it as well, and inner sub-second is the same shade as the mid-section, but it carries an ultra fine ring pattern, you see more often on the subsection, but rarely so fine, it’s only visible with a magnifying glass. The numerals are luminous as are the watch hands. The stainless-steel case has smooth brushed sides and the crown is nice and chunky offering a good grip and wind. We always recommend a back-and-forth winding to lower the stress on the spring. Imagine gripping it and letting loose with every wind, this causes unnecessary stress to the spring. So, winding back and forth gives the spring a stressless wind, and a longer life span. In other words, you don’t let the crown loose with every wind, you don't let the crown loose while winding period. It’s not easy to explain, once you’ve mastered it you will never forget, it’s like riding a bike. We reattached the band the Tissot watch came with, though I must ad that it feels rather dry, so it might well need a replacement.
