In September 2008 Casio revived the very popular Men In... series, that started in 1997 with the Men In Black models. The first new series is the Men In Rescue Orange. I like Orange, also it's the Dutch national color. Also I have had a lot of connections with the local lifeguard. This series is often abbreviated to MIRO. In September three Atomic models were released. Also  three non-Atomic models were released at the end of 2008. The non-Atomic models were called Rescue-G series, but have exact the same color scheme and were released only outside Japan.

Although not a MIRO model, the GW-M5600R is sometimes also referred as a MIRO model. It was actually a basic model. Men In... models are only Master of G's.
