Why buy each?

Fitbit Sense

Continuous EDA stress tracking

The EDA (electrodermal activity) sensor tracks physiological stress throughout the day — a feature absent from most competitors at this price.

6 months Fitbit Premium included

Comes with Fitbit Premium for advanced sleep analysis, HRV trends, stress management scores, and personalised health insights.

6-day battery, works with iPhone

Unlike Apple Watch or Galaxy Watch, Sense 2 pairs with any smartphone and runs 6 days before charging.

Suunto Race

Significantly improved heart rate accuracy

The redesigned optical HR sensor on Race 2 delivers far more reliable readings during high-intensity sessions — a notable weak point of the original Race that has been addressed.

Dual-frequency GPS at 55h

Dual-frequency L1+L5 multi-constellation GPS for sub-meter precision in urban areas and dense forests, with 55 continuous GPS hours on a single charge.

1.5" AMOLED, thinner and lighter

The display grows to 1.5" at 2000 nits while the case slims to 12.5mm and drops to 76g — more readable in sunlight and easier to wear day-to-day than its predecessor.
