TAG Heuer launches the Connected Calibre E5 45 mm × Formula 1, a titanium‑cased smartwatch timed to the start of the 2026 Formula 1 season. The ‘Race Track’ dial and a dedicated F1 app send the beat of every practice, qualifying session, and race straight to the wearer’s wrist.
2026 brought radical changes to the Formula 1 rulebook. The new hybrid power unit with roughly 50 % petrol (Advanced Sustainable Fuels) and 50 % electric split, and the tightened energy‑recovery and deployment force pilots to manage energy more carefully. Drivers and race engineers can actively select different energy‑recharging modes from braking and engine harvesting during the race. A major simplification of front‑wing elements and a reduced rear‑wing area require pilots to stay in lower gears for the slow corners and to be more deliberate with braking.
The new cars behave totally differently, and pilots are yet to find their speed and fall in love with the new kit. ‘To drive, it’s not a lot of fun, to be honest. It’s not very Formula 1‑like. It feels a bit like Formula E on steroids,’said Max Verstappen (Red Bull Racing). Lewis Hamilton (Ferrari) called the energy management ‘ridiculously complex,’ followed by a post saying, ‘This is going to be one hell of a season.’
Unveiled on 25 February 2026, the new TAG Heuer Connected Calibre E5 45 mm × Formula 1 lets racing fanatics follow the expected craziness of the 2026 Formula 1 season as it happens.
TAG Heuer in Formula 1
TAG Heuer has built its reputation on timing the fastest machines on Earth. The brand first entered Formula 1 as an official timekeeper in 1992, a partnership that lasted until 2003 and helped cement its status among the sport’s elite. After a hiatus, TAG Heuer reclaimed the official timekeeper mantle in 2025.
In 1968‑69, TAG Heuer (then simply Heuer) signed Swiss driver Jo Siffert as its very first brand ambassador. Siffert’s charismatic personality and daring driving style made him the perfect face for the brand, and the Autavia 1163 he wore earned the nickname ‘Siffert Autavia’. Siffert’s deal was groundbreaking: it was one of the earliest instances of a watch house aligning itself with a single driver rather than an entire team. The visibility of his wristwatch on the podium and in the pits helped cement Heuer’s image as the chronometer of speed.
TAG Heuer first entered Formula 1 as the official timekeeper in 1992. A year after it began its partnership with Brazilian champion Ayrton Senna, who chose the S/EL chronograph with its distinctive S‑shaped bracelet for the 1994 season. In 2025, TAG Heuer launched a two‑part ‘Designed to Win’ collection that revives Senna’s original S/EL design under the guidance of his niece Bianca Senna, one quartz, one automatic. The line is marketed as a tribute to the ‘greatest driver’ and reinforces the brand’s tagline ‘Don’t crack under pressure.’
Two‑time world champion Mika Häkkinen favored the TAG Heuer 6000 Series Chronograph, which he wore throughout his 1998 and 1999 title runs. The watch’s clean, white‑blue dial echoed the Finnish driver’s calm, precise approach on the track. TAG Heuer still highlights Häkkinen’s watch in its archival collections, underscoring the lasting impact of that partnership.
When Hamilton secured his first world championship in 2007, he paired his victory with a bright‑orange TAG Heuer Formula 1 Chronograph (Ref. CAH1113). The watch became instantly recognizable on his Vodafone‑branded helmet and continues to appear in his personal collection.
A Companion for the Season
The TAG Heuer Connected Calibre E5 45 mm × Formula 1 watch features a 45 mm Grade‑2 titanium case that is brushed, sandblasted, and finished with a black DLC coating for durability and a sleek, race‑ready aesthetic. The bezel curves around a high‑resolution AMOLED display, where the centerpiece is the “Race Track” watch face. Each Grand Prix weekend triggers an automatic redesign: the country flag, race name, and a stylised circuit silhouette appear beneath a digital time read‑out, while a moving dot traces the passing seconds along the track outline. Over the 24‑race season, owners will see a fresh dial for every race weekend.
The device runs on TAG Heuer OS, offering intuitive navigation, responsive haptics, and a suite of wellness sensors (heart‑rate, sleep, activity). Dual‑band GNSS ensures precise outdoor positioning, while a PPG sensor powers health tracking. Two strap options—black leather with carbon‑patterned rubber and a stretch‑textile band—provide both elegance and sport‑ready comfort.
A dedicated Formula 1 app embedded in the watch menu pulls data directly from the FIA. It delivers live calendars, session times, real‑time results, and driver/team standings. Smart widgets flash key updates without opening the app, letting the wearer stay tuned to the race even during a coffee break. Animated bezel markings and circular complications further break down the weekend schedule (FP1‑FP3, Q1‑Q3, race) at a glance.
As always, the 2026 Formula 1 season kicks off in Melbourne, Australia, on 6 March, ushering in a new era of hybrid power units and tighter competition. TAG Heuer’s Connected Calibre E5 45 mm × Formula 1 will be available for an exclusive 48‑hour pre‑order on tagheuer.com beginning 3 March 2026, with a broader retail rollout to follow shortly after.
