US company Jacob & CoA will be offering a special version of the striking Grand Complication Epic SF24 at the 6th Only Watch. It is the iconic GMT, in which a cylindrical 24 time zone indication resides at the top of the case, making a reference to the departure and arrival boards found at airports and railway stations around the world. In this unique edition, Paris has given way to Geneva (where the auction is conducted this year), while those who acquire the watch will be able to add their preferred city to the 24 zone indication.
