Thorn T012 Titanium NH34 GMT Diver

Thorn is a Chinese brand that sells direct, and the T012 is its titanium GMT diver, with a Grade 2 titanium case and caseback, 47 mm across and 14.8 mm thick including the crystal, rated to 200 m with a screw-in crown. The 120-click unidirectional bezel carries a dual-colour aluminium insert with a BGW9 lume dot at 12, and the dial uses Swiss C3 or vintage-toned lume. Inside is the Seiko-made NH34 automatic, which adds a 24-hour GMT hand and a date. The crystal is sapphire. It comes on a 22 mm leather strap, and Thorn covers it with a three-year warranty.
