Editor's Notes

Bremont's white gold and alligator 'Supersonic' watch is a tribute to the Concorde's 50th anniversary and the centenary of British Airways. Limited to a run of 100, it's been hand-assembled in the label's Henley-on-Thames workshop with a customised base plate and ring of aluminium from Alpha Bravo, the last remaining aircraft of its kind at Heathrow. It's engineered with an in-house BE-11M manual wind movement (the brand's first ever) and comes with a bespoke silver-tone stand.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. For more information, contact one of our experts by emailing
