Isotope GMT 0º Is The Innovative International GMT Watch

Isotope is a universal watch company based in Britain – on the very same meridian as Greenwich – recognising the centre of international horological significance with a dedicated, innovative watch, the GMT 0º.

The entirely bespoke Isotope GMT 0º replaces the function of the extra GMT hand with a distinctive dial design, featuring an Isotope Lacrima shaped cut out and the combination of a date dot and a GMT disc, which has never been used together before on the same dial (below).

The Lacrima shape is now part of the DNA of Isotope, present on all dials and in various details of all their watches. The second time zone is shown using the coloured indicator on the central disc. The date is indicated by a coloured dot visible through one of the 31 holes drilled into the multi-layered dial. Finally, the local time can be read conventionally the bespoke brushed hands created specifically to allow better legibility both in daylight or after dark.

The shape of the case itself is very special, not a traditional circle but the slightly oval form of the number ‘0’, a further nod to the prime meridian at zero degrees longitude. Turning over the brushed steel watch case you find an unusual half display screwed case back featuring the Lacrima shape, this time as a window, through which you can see the revolving rotor of the modified Swisstech automatic movement, signed by Isotope (below).

The solid portion of the case back is engraved with the hours of difference of the world’s major cities relative to GMT. With a special focus given to the Greenwich Meridian. On the screw-down crown, there is an intriguing motif designed by an industrial designer (the owner’s Uncle) with hundreds of unpublished designs. In the crown is engraved the symbol of the Infinite Chain, a sketch symbolic of union and eternal motion (below).

The watch comes with a quick-release Cordura strap with coloured stitching, matching the dial details. The case lugs design is mirrored in the buckle (below), proof that detail is imperative for the Isotope brand. It can also withstand diving up to 200m. The movement comes with an exclusive three-year warranty.
