The Bradner GMT Automatic is the latest diving watch from Hong Kong manufacturer Spinnaker. Its Japanese automatic GMT movement is designed to make it a reliable travelling companion, able to keep track of three time zones at once.
Encased in stainless steel, the 42 x 15mm watch is rated to a depth of 180m and has an anti-reflective sapphire lens. On the other side is an exhibition see-through caseback revealing the watch’s inner workings.

The new Bradner has Swiss luminous hands and indices and the inner rotating bezel is bi-directional. There are six colour choices: Sombre Red, Abbott Brown, Uniform Grey, Gravel Black, Parisian Night and Night Shadow.






The bracelet is a stainless-steel “beads of rice” design but the watch is also supplied with a rubber strap. The Spinnaker Bradner GMT costs £475.
Spinnaker has also launched a new 150m-rated watch, the Fleuss GMT Automatic, with a design it says draws on the golden era of vintage divers. It is available from 26 April.
The fourth in its GMT series, following the Dumas, Croft and Bradner, the newcomer has a Japan Automatic GMT movement, 43 x 15mm stainless-steel case, Swiss luminous hands and indices and anti-reflective sapphire lens.
It comes in five dial colours with contrasting uni-directional bezels: Deep Grey, Moon White, Tropical Green, Forest Green and Dark Cerulean Blue.





Complete with stainless-steel beads of rice bracelet and additional rubber strap, the Fleuss GMT Automatic is priced at £490.
Longines Hydroconquest GMT
Another watch offering multiple time zones, Longines’ new 300m Hydroconquest GMT models have 43mm diameter (13mm thick) cases so are slightly enlarged versions of the models launched last year, which had cases 2mm narrower.

The self-winding watches have a new ceramic unidirectional bezel, screw-in crown and caseback, anto-reflective sapphire glass and Super-LumiNova treatment of hands and indices.
The five versions – black, green or blue sun ray – come with a stainless-steel bracelet or a colour-keyed NATO strap made from recycled material. These new Longines models cost £2,600 to £2,800 depending on colour scheme.
