The N1 Rocket NH34-225A712L adds a second-time-zone display to a blue-dial automatic. A blue leather strap with pale contrast stitching complements the dial and bezel, while the 46mm steel case retains the N1 Rocket’s angular profile.
The TMI NH34 automatic GMT movement uses an additional hand against a 24-hour scale to track another time zone alongside the main time display. A date window sits at three o’clock. The movement has 24 jewels and more than 41 hours of power reserve when fully wound.
A bright-tipped GMT hand is easy to distinguish from the main hands. Super-LumiNova on the hands and dial markers assists low-light reading, and a 4.5mm domed K1 crystal covers the face. The screw-in exhibition back shows the automatic movement.
This version is supplied on blue leather with a 22mm fitting. The case measures 46mm across, 16.8mm thick and 55.4mm lug to lug. It carries a 200m water-resistance rating; keep the leather dry and use a suitable water-resistant strap for swimming. The base model is a 3,000-piece edition.

After swimming with a suitable strap, rinse the watch with fresh water and dry it. Avoid hot tubs and saunas, and follow the manufacturer’s servicing and water-resistance guidance.
