Enter TAG Heuer, the Swiss brand better known for the Monaco and Carrera chronographs, among other models. When it first set out to build a luxury smartwatch nearly a decade ago, the company approached the challenge in a uniquely Swiss way—through modularity.
Early versions of the Connected allowed buyers to literally swap between a digital smartwatch module and a traditional mechanical watch, the most elite option of which included a $17,000 tourbillon, blurring the line between horology and high tech.

Over time, though, TAG learned what its clientele truly appreciated from the piece. Four generations later, the Connected has shed its modular experiment roots and matured into a more focused, purpose-built smartwatch that fully embraces its digital identity while still carrying the premium material and design hallmarks of a more traditional Swiss watch.
The Connected Calibre E4 Golf Edition—Fleetwood’s wristwear of choice— has represented the clearest expression yet of TAG’s luxury smartwatch vision for several years now.
Available in a lightweight 42mm or 45mm titanium case, it’s built with golfers squarely in mind. Beyond standard fitness tracking, it layers in dedicated tools like 3D mapping for over 40,000 courses, shot tracking, digital scorecards, and swing analysis. Paired with TAG’s companion app, it aspired to be more of a personal caddie on the wrist than a traditional timekeeper.
