Since 1860, when Edouard Heuer first established his workshop in Saint Imier, TAG Heuer has stood at the crossroads of precision and performance. From dashboard timers that accompanied the golden age of motoring to wrist bound chronographs that measured triumphs in milliseconds, the maison has long cultivated a dialogue with speed. Its relationship with Formula 1 is not a mere sponsorship but a shared philosophy, one that venerates accuracy under pressure and elegance under duress. It is within this continuum that the TAG Heuer Connected Calibre E5 45mm x Formula 1 Edition (Ref. SBT8A85.EB0417) emerges. This is not simply a smartwatch dressed in racing livery. It is a contemporary instrument, engineered for those who inhabit a world where lap times, heart rates and deadlines are equally unforgiving.
Power Beneath the Surface
At its core beats the Calibre E5 platform, powered by the Qualcomm Snapdragon 5100+ chipset, ensuring fluid navigation and reliable performance. Battery life extends to two days at full performance and up to three days in Low Power Mode, a pragmatic nod to modern mobility. Charging to 100 percent takes a brisk 90 minutes within optimal temperatures between 15 and 45 degrees Celsius. For those perpetually on the move, just 30 minutes of fast charging yields a full day of battery life.
The hardware suite reads like a manifesto of contemporary wellbeing. Heart rate monitoring, calories, step counting and sleep tracking are complemented by blood oxygen saturation, breathing rate and heart rate variability metrics. An accelerometer, gyroscope and barometer enhance motion and altitude awareness, while a compass and dual band GNSS provide geographical precision. Supporting GPS, GLONASS, BeiDou, QZSS and Galileo across L1 and L5 frequencies, the watch is as comfortable mapping a mountain trail as it is timing a city run. An AMOLED tactile display measuring 1.39 inches delivers a 454 by 454 resolution at 326 dpi, offering crisp legibility beneath a flat sapphire crystal. Two mechanical push buttons, a mechanical crown, microphone, speaker and refined haptics ensure interaction remains intuitively physical rather than abstractly digital.
The TAG Heuer OS Experience
Running on TAG Heuer OS, the user experience is distinctly curated. Exclusive Formula 1 watch faces dominate the visual theatre, transforming the dial into a digital paddock of racing inspired graphics and complications. The TAG Heuer Sports Watch App encompasses running, cycling, swimming, workouts, hiking and golf, alongside the broader TAG Heuer Wellness ecosystem.
The dedicated Formula 1 app and widgets provide race centric updates, extending the brand’s motorsport lineage into daily life. Call management through a paired compatible smartphone, voice assistant control, media management and notifications integrate seamlessly, while branded utilities such as Stopwatch, Timer, Alarm and Calendar preserve the house’s chronometric pedigree.

A Case Cast in Speed
The 45mm case, fashioned in black DLC grade 2 titanium with brushed and sandblasted finishes, strikes a confident yet lightweight profile. A black polished ceramic bezel bears Formula 1 phase engravings, lending tactile symbolism to its racing allegiance. The black steel crown, sheathed in black rubber, is flanked by two black DLC steel push buttons at 2 o’clock, and 4 o’clock, each accented with red lacquer, a subtle evocation of pit lane urgency. A black DLC grade 2 titanium caseback secures the architecture, while water resistance to 50 metres ensures resilience against the unexpected. It is a construction that balances sport with sophistication, performance with poise.
Strap and Statement
The bi material strap adheres faithfully to Formula 1 colour codes. Black leather with a carbon pattern overlays a black rubber base, punctuated by assertive red stitching. The black interchangeable DLC steel folding clasp, equipped with double safety push buttons and adorned with the TAG Heuer shield, ensures both security and style.
In the final analysis, the TAG Heuer Connected Calibre E5 45mm Formula 1 Edition is less an accessory and more an assertion. It proclaims that heritage need not be static, that tradition can evolve without dilution. In marrying the visceral thrill of Formula 1 with the intelligence of contemporary wearable technology, TAG Heuer once again reminds us that time, like speed, is best mastered with precision.
