There have been a few questions on the changes made to the Connected for 2016. The first batch from 2015 quickly sold out and there was a significant delay until production ramped up to supply the second batch. Case Changes? No, the watch is exactly the same and there is no change to case materials- still titanium grade 2. The photos that look as though the case is steel is just a trick of the light. The only thing that changes is that TAG Heuer are starting to assemble the Connected in Switzerland. Serial Numbers Watches with a serial number starting with "GL" means it is from the very first batches of production; serial number starting with "PE" means it is from the latest batches of production. Swiss Engineered As some people have noticed, the text "Swiss Engineered" appeared on the bottom of the bezel on the first watches and has been removed. Why? Here is the answer direct from TAG Heuer: Swiss authorities represented by the Federation of the Swiss watch industry are debating about the "Swiss" mention for Connected watches since the legislation which came into force in 1972 will be altered in January 2017. TAG Heuer awaits the official decision of the Federation of the Swiss watch industry to continue or not to use the "Swiss Engineered". Until any decision is made, TAG Heuer decided to remove the mention "Swiss Engineered" until further notice.
