Garmin Venu 3S GPS
Garmin is to the world of sports watches what Leica is to cameras or Aston Martin is to cars: a timeless classic that has it all down to the last detail. Over the course of two decades, their engineers have become almost Zen-like masters of health tracking – and that’s why the Garmin Venu 3S is something special. This isn’t a watch that screams “marathon!” – this is a watch that whispers “namaste.”
For those who are looking for more than just sun loungers on holiday, but also inner peace, the Venu 3S is a winner. With relaxing breathing exercises, guided meditations and ambient sounds that will calm even the first person to check their email on a Sunday morning, this watch is a real little guru for your wrist. All beautifully packaged in an AMOLED display that doesn't let itself be distracted by the midday Mediterranean sun.
But the Venu 3S is not just a digital spa. It has more than 30 sports apps – including those for wheelchair users, which is a move that is hard to praise. In addition to the classic repertoire (sleep, heart rate, steps, energy), the watch also has functions for golf, swimming, and even a jet lag advisor. Yes, jet lag can now get its digital slap. Definitely a must-have on the list – smart fitness trackers 2025.
And then there's multimedia: speaker, microphone, music playback, answering calls... But don't panic - it's not a mini smartphone, because all these goodies only work in conjunction with your mobile phone and the Garmin Connect app. PURCHASE
Battery life: up to 14 days
Warranty: two years
Subscription: not necessary
Advantages: Sun-resistant AMOLED display + serious wellness features for modern digital zen.
Disadvantages: No trail running – mountain trail runners, look no further.
Apple Watch Ultra 2 GPS + Cellular
If the Garmin Venu is a Zen master for a digital spa day, the Apple Watch Ultra 2 is its mountain Sherpa cousin – muscular, tough, and ready for anything. With the Ultra line, Apple has shown that it can make a smartwatch that is not just a fashion accessory, but a true tactical device for adventurers, divers, and fans of technologically sophisticated survival.
The Ultra 2 is so rugged you could probably use it as an emergency hammer. Its 49mm titanium case, sapphire crystal, and 3,000-nit Retina display are not afraid of even the strongest mountain sun—or the deepest dive. Yes, you read that right—the watch is dive-ready to 40 meters and comes with the Oceanic+ app, which essentially turns it into a dive computer on your wrist.
And when you're not climbing or diving, the Ultra 2 can handle all the classic smart features - from ECG, blood oxygen measurement and sleep monitoring to tracking almost any form of movement, including those you thought didn't need measuring (hiking with a monkey on your shoulder? Why not!). Add dual-frequency GPS for ultra-precise location and the new Double Tap feature for touch-free operation, and you've got an almost cinematic survival gadget. Definitely our favorite on the list of smart fitness trackers 2025!
The watch can play music, take calls, send messages – all independently of your phone, if you have the eSIM feature activated. But beware: like everything Apple, this watch is exclusive to the iPhone ecosystem. If you use Android, you can only admire it in a shop window. PURCHASE
Battery life: up to 36 hours (72 hours in low power mode)
Warranty: one year (can be extended with AppleCare+)
Subscription: not required (LTE features require a mobile plan)
Advantages: Extremely bright display, robust design, advanced features for sports, diving and wilderness survival.
Disadvantages: High price and exclusive iPhone connection – Apple traditionally doesn't like to share toys.
