It is two years since Bremont and Bamford Watch Department collaborated on their first watch together, the Bremont S500 Bamford Special Edition.
That relationship has survived the transfer of power at Bremont to new CEO Davide Cerrato, with the two companies unveiling a similarly-styled version of the Supermarine S502 GMT.
Like the first collaboration piece, the watch has a California-style dial that mixes symbols with Arabic and Roman numerals for hour markers.
The dial is made from two plates with green lume on the lower layer beaming through hour markers cut into the upper black surface.
It is the green of this lume that gives the watch its name, the Bremont Bamford Aurora, and associates it with the Aurora Borealis, or Northern Lights.
The green is used on the 24 hour second time zone bezel; hours, minutes, seconds and GMT hands; and stitching for its black leather strap.
Fun fact: 2024 is expected to bring the brightest Aurora in over 20 years.
Mr Cerrato says he has always been fascinated by the challenge of creating a timepiece that is as compelling in the dark as it is in the light. “Working with George [Bamford], I am thrilled that we have achieved a luminous show which mirrors the magic and spectacle of the aurora borealis,” he adds.
The 43mm black DLC-treated steel watch is a limited edition of 500 pieces priced at £4,900.
