Two of the most anticipated G-Shock releases of 2019, the full-metal titanium GMW-B5000TB-1 and GMW-B5000TCM-1, are now officially discontinued and are no longer in production, according to g-shock.jp. Although this is not a surprise, as both models were known to be limited production pieces but to have it discontinued a month after launch is unprecedented.
