Casio has announced a new addition to its MR-G watch series, the MRG-D5000 Blue Sapphire, to mark the 30th anniversary of the product line, and to be honest, the new timepiece looks absolutely gorgeous.

Design Details

This watch features an exterior case built using blue sapphire crystal. Because sapphire is rigid and can be prone to shattering under direct impact, the company implemented a specific Multi-Guard Structure to maintain the shock resistance the brand is known for.

The sapphire crystal is paired with titanium components that have been treated with a diamond-like carbon (DLC) coating. This combination keeps the watch’s weight at 121 grams. Its dimensions are 51.1 x 43.2 x 16.5 mm. The face design includes a blue brick pattern, and the watch is fitted with a Dura Soft rubber strap that secures via a newly designed one-touch three-fold clasp.

Internally, the MRG-D5000 operates on the Tough Solar power system, which reliably converts light into energy to keep the device running. The rechargeable battery provides up to 11 months of operation under normal conditions without light exposure, and up to 22 months when stored in the dark with the power-saving function enabled.

For time accuracy, the watch uses Multi Band 6 technology. This allows it to receive radio-controlled time calibration signals up to six times a day from stations in Japan, North America, the UK, Germany, and China.

The watch includes 200-meter water resistance, a 1/100-second stopwatch, a 24-hour countdown timer, and world time functionality covering 38 time zones. It also features five daily alarms, an automatic calendar, and a white LED backlight for visibility in low light.

Casio is limiting the production of the MRG-D5000 Blue Sapphire to 20 units worldwide. Each watch will feature a screw-lock back plate engraved to indicate its limited-edition status and will be shipped in specialized packaging.

In related news, Casio has recently launched a pastel pink G-Shock in the US with a special pink ribbon detail, alongside three affordable FB100W watches featuring Bluetooth connectivity and step tracking.
