The New Bremont Supermarine 300m GMT Collection

Combining a dive watch with a traveller’s function has become a classic over the years, offering immense versatility.  At Bremont, this concept was personified for many years by the Supermarine S302 GMT Diver, but since the brand is currently restructuring its strategy and collection, many expected to see a new model occupying this specific niche. Based on Bremont’s new vision of a dive watch, the redesigned Supermarine 300m, here’s its traveller’s counterpart. And no surprises, it’s named the Supermarine 300m GMT. 

If you’ve followed the news recently, you might be aware that change and evolution are the new keywords at Bremont. Like it or not, the brand has chosen a path and seems to be sticking to a strategy designed to bring fresh air to the communication, the visuals and, of course, most of its collections. While we’ve been told that the Trip-Tick case and winged logo are not things of the past but will be reserved for certain models (mostly pilot-oriented models), the brand’s dive watch has undergone a substantial facelift; it’s actually a brand new watch altogether.

Using the recent Supermarine 300m architecture and design, the new Supermarine 300m GMT Collection is as straightforward as its name suggests: the same shape, most proportions and features retained, the addition of a GMT hand and classic travel-oriented features. As such, the 904L steel is identical in shape and proportions, with a 40mm diameter and a 48mm length. It’s more classic in design, with a sleeker (no more striped container), slimmer profile and asymmetrical shape. The 30-bar-resistant case features a screw-in crown and solid steel back, and the classic 60-minute bezel has been replaced by a two-tone aluminium insert with a 24-h scale. The added GMT function brings the thickness to a reasonably decent 13mm.

Some changes are also noticeable on the dial side, with the addition of colours. The Supermarine 300m GMT is presented in three different iterations, with gradient dials and matching bezel inserts. You can choose between Tundra Green, Glacier Blue and Ember Red. The models share the same dial concept as the time-and-date Supermarine 300m, with an inverted arrow at 12 o’clock and a combination of applied dots and trapezoidal-shaped markers for the hours. Also, you’ll see that the new Wayfinder logo has been reduced in size (thanks to feedback from fans). The arrow-shaped hand and Supermarine mention are picked up in contrasting colours – orange or red.

Inside the case is a so-called office GMT movement, with an independent 24-hour central hand. The movement is sourced from Sellita and is based on the SW330 architecture, with a 4Hz frequency and a 50h power reserve. Bremont lets you choose between its nicely executed and fluid 904L multi-link steel bracelet, with micro-adjustment on the clasp, or a rubber strap – both with a quick-release device.

The Bremont Supermarine 300m GMT Tundra Green is presented as part of the permanent collection. The Glacier Blue model is limited to 500 pieces, and the Ember Red model is a 200-piece boutique-only version. It’ll be priced at EUR 4,600 on a steel bracelet and EUR 4,300 on a rubber strap.
