In 1972, HMT expanded its watch manufacturing capacity with a set up alongside the Bangalore Factory to manufacture additional watches. In 1975, the watch factory at Bangalore was further expanded to manufacture main spring, hair spring and shock absorber components. HMT set up additional manufacturing facilities to produce watch components sets at Tumkur in 1978 and at Ranibagh in 1985. The factory at Tumkur was partially converted to manufacture quartz analog watches in collaboration with Citizen. To cater to the niche market, a specialised watch case manufacturing facility was set up at Bangalore in 1983.
