Following approximately six years of a joint development between Casio and Nippon Steel — the two companies have created an enhanced titanium alloy called “Tran Tixxii.”

The titanium is lightweight and hypoallergenic like other titanium alloys used for watchmaking, however, this special alloy has twice the hardness of pure titanium and allows the surface to be polished to a mirror finish that’s aesthetically comparable to stainless steel.

As with the previous full metal 5000 series G-Shock watches, this measures 43.2 mm x 49.3 mm with a thickness of 13 mm. Even with a full metal bracelet, it weighs only 104 grams though. This is a significant decrease compared to the steel variants. The 5000 Series has been offered in titanium previously, but not in this alloy.

To introduce the new material G-Shock created the GMW-B5000TR-9 “Tran Tixxii” which features a gold IP (ion-plated) case with the pushers and bracelet treated with a multi-colored IP (red, blue, light gray, dark gray, gold), resulting in an unmistakable wrist presence.

While the insides and dimensions of the GMW-B5000TR-9 are the same as with past full metal 5000 G-Shocks — including a screw-locked caseback, sapphire crystal, 200 meters of water-resistant, Bluetooth and atomic time syncing, and a solar-powered movement — the price will be higher than most existing models. Retail is $1,700 and it will be available later this year.
