You get into the pool and the first thing you do is leave the watch in the locker. On Sunday you go up the mountain and return with the route full of zigzags between the pines. And on Thursday, before the long shoot, the charger appears. Three different workouts, three different problems, and always the same thing in the middle. The Zeblaze Stratos 4 Pro goes for those three, which is just what I ask of a watch when the week doesn't look like the previous one. Now you have it for €71.13 on AliExpress with the code BDES04. It lasts 5 ATM, so you can swim with it on. It's not for diving, but it's perfect for doing lengths on a Tuesday and saves you a trip to the ticket office. In the mountains GPS rules, and here it connects with six satellite systems and on two frequencies at the same time. Translated: the route comes out clean in the area of ​​trees, where the most basic clocks draw those saw teeth that no one can then match. With the most precise mode it lasts 38 hours, so a weekend trip does not force you to ration. Zeblaze claims up to 60 days in saving mode, 30 in normal use and 18 in hard use. In practice it goes down quite a bit from there: each outing with GPS, music and flashlight on eats up the battery at a different rate. Still, we're talking weeks between charges, not days. Music is one of the things that is most noticeable: it fits on the watch itself, so you can go out for a ride with headphones and leave your phone at home. And the two-color flashlight resolves pre-dawn outings better than the screen turned on full blast. The screen is 1.43-inch AMOLED with Gorilla Glass and is bright enough to read the pace at midday without glancing at it with your hand. The bezel is made of steel and the 22 mm strap can be changed in a moment. Of course, the case measures 49 mm: on thin wrists it is noticeable, and quite noticeable. Go through 170 training modes and measure pulse, oxygen, stress and sleep. It is a record to see the evolution of the week, not a laboratory: if you live focused on running power or maps to navigate, that is not your field. The Pro is recent and is barely seen in stores here. If it runs out or rises, the Stratos 4, of which this is the evolution, continues to circulate. For what you pay today for a watch that is limited to counting steps, this one swims, climbs the mountain with a clean trail and lasts the month.
