GST-B400MV-5A

Indulge your passionate side. Stargaze with that special someone wearing your matching set of timepieces inspired by Mars and Venus.

These watches set up a romantic pairing that is out of this world, inspired by the beautiful Venus and the heroic Mars. The G-STEEL bezel comes in reddish copper to evoke the hue of Mars, while the G-MS gracefully boasts case, hands, and other details in gold against a dark brown band, conjuring the shimmering image of Venus in the night sky.

Both pair with a smartphone via Bluetooth®. The dedicated app coordinates with Internet timeservers to keep you and your loved one on time and in sync, wherever you are in the world.
