Sometimes it’s fun to build up to something big and sign off for the week with a bang but other times the proverbial big kahuna is so good that you can’t help but spill the beans early. This week I thought I’d come right out of the gate with what’s undoubtedly one of the most impressive watches to be offered this year. And no it’s not a Rolex or a Patek.
