As a result of President Trump’s “List 4” tariffs which took effect on September 1, 2019, Casio is shifting the production of its wristwatches (destined for the U.S. and including G-Shock) from China to Thailand. The tariffs impose a 15% tariff on 91.6% of apparel imports from China. According to a report from Japan, this change of production facilities was implemented on September 3, 2019. Casio already has factories in Thailand where a lot of G-Shock watches are produced for worldwide markets, so the transition is likely to go smoothly and without any disturbance to consumers.
The made-in-China G-Shock watches are usually the more affordable models, though some pricier models like the G-STEEL GST-B100, G-STEEL GST-B200 and GM-5600 were also being manufactured there, according to www.e-casio.co.jp.
In addition to China and Thailand, Casio also has factories in Japan where it makes some of the higher-end G-Shock models and collaboration watches.
