And I believe it is hand engraving on enamel (I’ve forgotten, to be honest). The engraving is of the Artemis boat that UN co-sponsored in the 2016 or 2017 America’s Cup held in Bermuda I attended the race as a guest of UN along with our esteemed AP moderator MichaelC. It was a great time. The watch is one of 35 made for the occasion. It has a 10 minute countdown complication in addition to the usual chronograph function. Thanks for looking. M4
